The embodiment of the application provides a display device and a display method thereof, which solve the problems that the resolution of the existing stretchable display screen is reduced after stretching, and the resolution of the display screen is different before and after stretching, so that the experience of a user watching the display screen is affected.
Example 1
Referring to fig. 1, a display device provided in an embodiment of the present application includes a stretchable display panel 100 and a control circuit 200, where the stretchable display panel 100 includes a stretchable substrate 1 and a plurality of rows and columns of pixel islands 2 disposed on the stretchable substrate 1 in an array arrangement, and the pixel islands 2 include first pixels 20, where the first pixels 20 are R, G, B pixels in fig. 1. The pixel island 2 may include a rigid substrate and the first pixel 20 disposed on the rigid substrate, the rigid substrate may be made of a rigid material, and the rigid substrate is disposed on the stretchable substrate 1, such that when the stretchable substrate 1 is stretched, only a portion except for a portion contacting the rigid substrate is not deformed, and other portions of the stretchable substrate 1 are all deformed, and since the first pixel 20 is disposed on the rigid substrate, the first pixel 20 is not deformed and an area is not changed when the stretchable substrate 1 is stretched.
Along the first direction, a second pixel 3 is adjacently arranged on the same side of each first pixel 20 to form a plurality of pixel groups 10, and the light emitting colors of the first pixel 20 and the second pixel 3 in the same pixel group 10 are the same; the first direction refers to a stretchable direction of the stretchable display panel 100; the second pixels 3 are made of a deformable material; the control circuit 200 is configured to control the driving voltage input timings of the first pixel 20 and the second pixel 3 within the same pixel group 10 to be the same when the stretchable display panel 100 is not stretched and is in a display state; and controlling the driving voltages of the first pixel 20 and the second pixel 3 in the same pixel group 10 to be input in time sequence when the stretchable display panel 100 is stretched in the first direction and is in the display state.
It should be noted that, along the first direction, a second pixel 3 is disposed adjacent to the same side of each first pixel 20 to form a plurality of pixel groups 10, that is, each first pixel 20 has a second pixel 3 corresponding to the first pixel, and the first pixel 20 and the second pixel 3 corresponding to each other form a pixel group 10. When the stretchable display panel 100 is not stretched and is in a display state, the driving voltage input timing sequences of the first pixel 20 and the second pixel 3 in the same pixel group 10 are controlled to be the same, and the first pixel 20 and the second pixel 3 in the same pixel group 10 emit light simultaneously due to the fact that the second pixel 3 has a tiny area when not stretched, that is, the first pixel 20 and the second pixel 3 in the same pixel group 10 are displayed as a whole, and the driving voltage is input at the same timing sequence. When the stretchable display panel 100 is stretched in the first direction and is in the display state, the driving voltages of the first pixel 20 and the second pixel 3 in the same pixel group 10 are controlled to be input in a time-division manner, that is, the driving voltages of the first pixel 20 and the second pixel 3 in the same pixel group 10 are input in a time-division manner, and since the second pixel 3 is stretched to have a larger area, the first pixel 20 and the second pixel 3 in the same pixel group 10 need to be displayed separately.
With the above arrangement, although the distance between two adjacent first pixels 20 in the first direction is increased due to the stretching of the stretchable display panel 100, the compensation display of the second pixels 3 does not reduce the number of pixels that emit light per unit area too much, thereby reducing the phenomenon that the resolution of the stretchable display panel 100 is reduced after the stretching in the first direction, so that the resolutions of the display panel before and after the stretching are similar, and improving the user experience.
Wherein, the fact that the stretchable display panel 100 is not stretched and is in the display state means that the stretchable display panel 100 is in a natural state, and neither the stretchable substrate 1 nor the second pixels 3 are subjected to stretching force in any direction. The stretchable display panel 100 being stretched in the first direction and in the display state means that the area of the second pixel 3 is stretched to a target area size, which may be set according to a specific display condition, after the stretchable display panel 100 is stretched, but it is required to ensure that the second pixel 3 of the target area can be displayed as an independent pixel. By way of example, the second pixel 3 in the embodiment of the present application may be set to have a size of 8-12 micrometers in the first direction when not stretched, so that it is ensured that the second pixel 3 can be stretched into one independently displayable pixel for display within the stretchable range of the stretchable display panel 100.
In some embodiments, a stretching sensing module 4 is further disposed on the stretchable substrate 1, and the stretching sensing module 4 is electrically connected to the control circuit 200, and the stretching sensing module 4 is used for sensing the stretching degree of the stretchable substrate 1. In this way, the stretching degree of the second pixel 3 can be determined according to the stretching degree of the stretchable cable sensed by the stretching sensing module 4, so as to determine whether the second pixel 3 is stretched to the target area, so as to determine that the stretchable display panel 100 is stretched and in the display state, thereby accurately controlling the time-sharing input of the driving voltages of the first pixel 20 and the second pixel 3 in the same pixel group 10, and effectively avoiding that the area of the second pixel 3 does not reach the target area, and the driving voltages are input to the first pixel 20 and the second pixel 3 in time-sharing mode, so that the brightness displayed by the second pixel 3 and the first pixel 20 on the display panel is uneven, and the display effect is affected.
It should be noted that, the stretch sensing module 4 in the embodiment of the present application is only for sensing the stretched degree of the stretchable substrate 1, so as to determine the stretched degree of the second pixel 3 according to the stretched degree, so as to determine whether the area of the second pixel 3 reaches the target area, so as to input the driving voltage to the first pixel 20 and the second pixel 3 in the same pixel group 10 in a time-sharing manner. The specific structure of the stretch sensing module 4 is therefore not particularly limited herein.
In some embodiments, the stretchable substrate 1 is provided with at least one conductive line extending along the first direction; the wire is electrically connected to the control circuit 200, the control circuit 200 is further configured to detect a resistance of the wire, and determine that the stretchable substrate 1 is stretched in a first direction when the resistance of the wire increases from an initial value to a first threshold value, that is, the stretchable display panel 100 is stretched in the first direction, and at this time, the second pixel 3 is stretched to a target area size, and the control circuit 200 can control the first pixel 20 and the second pixel 3 in the same pixel group 10 to input driving voltages in a time-sharing manner.
In some embodiments, referring to fig. 2-3, the first direction is a column direction Y, and each row of first pixels 20 is provided with a row of second pixels 3 on the same side in the column direction Y; the first pixel 20 and the second pixel 3 in the pixel group 10 are located in the same column; the control circuit 200 is configured to control the driving voltage input timings of the adjacent two rows of the first pixels 20 and the second pixels 3 to be the same when the stretchable display panel 100 is not stretched and is in the display state; and controlling the driving voltages of the adjacent two rows of the first pixels 20 and the second pixels 3 to be inputted in time-sharing order when the stretchable display panel 100 is stretched in the column direction Y and is in the display state.
In this way, the second pixels 3 corresponding to one row are disposed on the same side of each row of the first pixels 20 of the plurality of rows of the first pixels 20 arranged along the column direction Y, when the stretchable display panel 100 is stretched along the column direction Y, the second pixels 3 are also pulled up, and the second pixels 3 are displayed as independent pixels, and the control circuit 200 inputs driving voltages to the first pixels 20 and the second pixels 3 in a time-sharing manner, so that the number of pixels in a unit area is slightly different from the number of pixels in a unit area when the stretchable display panel 100 is not stretched, so that the resolution is not greatly affected, and the display effect of the stretchable display panel 100 is not reduced.
It should be noted that, referring to fig. 2 to 3, the stretchable direction of the stretchable display panel 100 is the column direction Y, and each row of first pixels 20 is provided with a row of second pixels 3 on the same side in the column direction Y, so that each first pixel 20 has a corresponding second pixel 3, and the light emitting colors of the first pixels 20 and the second pixels 3 corresponding to each other are the same, and when the stretchable display panel 100 is not stretched, each first pixel 20 is simultaneously displayed with the corresponding second pixel 3 as a whole, so that the overall display brightness of the stretchable display panel 100 can be ensured to be more uniform. When the stretchable display panel 100 is stretched, the number of rows of the second pixels 3 is the same as the number of rows of the first pixels 20, so that the pixel distribution on each place of the stretchable display panel 100 can be ensured to be uniform, the change of the number of pixels in a unit area can be ensured to be tiny, and the problem of poor display effect caused by different resolutions of the stretchable display panel 100 before and after stretching can be avoided.
Specifically, referring to fig. 4, the first pixels 20 of each row may be connected together by a connection line, and the first pixels 20 of each row may be connected to a first gate driving circuit, the second pixels 3 of each row may also be connected together by a connection line, and the second pixels 3 of each row may be connected to a second gate driving circuit, both of which are electrically connected to the control circuit 200, the first gate driving circuit being for scanning the first pixels 20 row by row in the column direction Y, the second gate driving circuit being for scanning the second pixels 3 row by row in the column direction Y, GA1 in fig. 4 representing the scanned first pixels 20 of the first row, gan representing the first pixels 20 of the nth row, gb1 representing the scanned second pixels 3 of the first row, and gbn representing the scanned second pixels 3 of the nth row.
In some embodiments, a conventional GOA model may be used to drive voltage inputs for each stage of the scan, such as the common 23T1C/21T1C/11T1C model.
When the stretchable display panel 100 is not stretched and is in the display state, the control circuit 200 controls the first pixel 20 and the second pixel 3 to be simultaneously input in sequence, specifically, as shown in fig. 5, the first gate driving circuit scans the first pixel GA1 in the first row and the second gate driving circuit scans the second pixel GB1 in the first row at the same time, the control circuit 200 simultaneously inputs the same driving voltage to the scanned GA1 and GB1, then simultaneously scans the second row, and the control circuit 200 simultaneously inputs the same driving voltage to the scanned GA2 and GB2 until the last row is scanned. Thus, the first pixels 20 in the first row and the second pixels 3 in the first row are driven to emit light simultaneously, and the second pixels 3 have small areas when not stretched, so that the display effect is tiny, and the first pixels 20 and the second pixels are regarded as a whole to be displayed simultaneously, thereby not only not affecting the resolution, but also enhancing the display brightness of the display panel and being beneficial to improving the display effect.
When the stretchable display panel 100 is stretched in the column direction Y and is in the display state, the control circuit 200 controls the first pixel 20 and the second pixel 3 to input the driving voltages in time-sharing manner, specifically, as shown in fig. 6, the first gate driving circuit scans the first row first pixel GA1, the control circuit 200 inputs the driving voltages to the scanned first row first pixel GA1, then the second gate driving circuit scans the first row second pixel GB1, the control circuit 200 inputs the driving voltages to the scanned first row second pixel GB1, then the first gate driving circuit scans the second row first pixel GA2, the control circuit 200 inputs the driving voltages to the scanned second row first pixel GA2, and sequentially inputs the driving voltages in the order of GA1, GB1, GA2, GB 2. Thus, each row of the second pixels 3 is separately displayed with each row of the first pixels 20, for example, the first pixels 20 have four rows, the second pixels 3 have four rows, after the second pixels 3 are stretched and enlarged, the area difference between the second pixels 3 and the area of the first pixels 20 is tiny, the pixels which can be separately displayed on the stretchable substrate 1 are equivalent to eight rows, and eight rows of pixels are scanned in turn and driving voltages are input, so that the pixels of the display panel can be uniformly distributed and displayed, and the number of pixels in the unit area cannot be changed too much, so that the difference of resolution of the stretchable display panel 100 before and after stretching is not large, and the display effect of the stretchable display panel 100 cannot be affected.
In this embodiment, two independent GOA models are used to respectively feed signals to the first pixel 20 and the second pixel 3, and of course, one GOA model may also be used to feed signals to the first pixel 20 and the second pixel 3. Specifically, when the stretchable display panel 100 is not stretched and is in a display state, a set of GOA models is used to simultaneously supply signals to the first pixel 20 and the second pixel 3, so that the first pixel 20 and the second pixel 3 in the same pixel group 10 are simultaneously displayed to emit light as a whole. When the stretchable display panel 100 is stretched in the column direction Y and is in the display state, a set of GOA models is used to supply signals to the first pixel 20 and the second pixel 3 in the same pixel group 10, and it should be noted that a set of time-sharing control time-sequential control GOA models is required to supply signals to the first pixel 20 and the second pixel 3 in the same pixel group 10 in a time-sharing manner, so as to ensure that the driving voltage input time sequence of the first pixel 20 and the second pixel 3 reaches the time sequence shown in fig. 5 and 6.
In some embodiments, referring to fig. 2-3, along the column direction Y, each second pixel 3 has a size smaller than the size of the first pixel 20 in the same column; along the row direction X, the size of each second pixel 3 is equal to the size of the first pixel 20 in the same column. In this way, the second pixels 3 can be made smaller in area when not stretched, and can be displayed as a whole with the first pixels 20, and the second pixels 3 can be made substantially the same area as the first pixels 20 after stretching, and the second pixels 3 can be displayed alone, thereby ensuring that the number of pixels per unit area is not significantly reduced, the difference in resolution before and after stretching of the stretchable display panel 100 is not large, and the display effect is not affected.
It should be noted that, since the stretchable direction of the stretchable display panel 100 is the column direction Y, the size of the second pixel 3 in the column direction Y may be increased by stretching, while the size of the second pixel 3 in the row direction X is unchanged, so that the size of the second pixel 3 in the row direction X needs to be set to be the same as the size of the first pixel 20 in the same column in the row direction X, and the size of the second pixel 3 in the column direction Y is set to be smaller than the size of the first pixel 20 in the same column in the column direction Y, so that the size of the second pixel 3 in the column direction Y becomes larger when the second pixel 3 is stretched, so that the area of the second pixel 3 is kept substantially the same as the area of the first pixel 20 in the same column.
In some embodiments, referring to fig. 3, the size of each second pixel 3 in the column direction Y of the same row of second pixels 3 is the same. In this way, the areas of the second pixels 3 in the same row after stretching are the same, so that the first pixels 20 and the second pixels 3 are uniformly distributed, and the display effect of the whole display panel is better.
In the first embodiment of the present application, the second pixel 3 located between two adjacent first pixels 20 is located in the middle of two adjacent first pixels 20 along the first direction. That is, along the column direction Y, a row of second pixels 3 located between two adjacent rows is located at the middle position of two adjacent rows of first pixels 20, so that after the second pixels 3 are stretched, the distance between the second pixels 3 with the enlarged area and two adjacent first pixels 20 is equal, so that the distribution of the first pixels 20 and the second pixels 3 is more uniform, and the improvement of the display effect is facilitated.
Example two
Referring to fig. 7 to 8, the display device according to the second embodiment of the present application is different from the first embodiment only in the stretchable direction of the stretchable display panel 100. In the second embodiment of the present application, the first direction is the row direction X, and each column of the first pixels 20 is provided with a column of the second pixels 3 on the same side in the row direction X; the first pixel 20 and the second pixel 3 in the pixel group 10 are located in the same row; the control circuit 200 is configured to control the driving voltage input timings of the first pixel 20 and the second pixel 3 in the same row to be the same when the stretchable display panel 100 is not stretched and is in a display state; and controlling the driving voltages of the first and second pixels 20 and 3 in the same row to be inputted in time-series when the stretchable display panel 100 is stretched in the row direction X and in the display state.
In this way, a corresponding row of the second pixels 3 is disposed on the same side of each row of the first pixels 20 of the plurality of rows of the first pixels 20 arranged along the row direction X, when the stretchable display panel 100 is stretched in the row direction X, the second pixels 3 are also pulled up, and the second pixels 3 are displayed as independent pixels, and the control circuit 200 inputs driving voltages to the first pixels 20 and the second pixels 3 in a time-sharing manner, so that the number of pixels in a unit area is slightly different from the number of pixels in a unit area when the stretchable display panel 100 is not stretched, so that the resolution is not greatly affected, and the display effect of the stretchable display panel 100 is not reduced.
It should be noted that, referring to fig. 7 to fig. 8, the stretchable direction of the stretchable display panel 100 is the row direction X, and each column of first pixels 20 is provided with a column of second pixels 3 on the same side in the row direction X, so that each first pixel 20 has a corresponding second pixel 3, and the light emitting colors of the first pixels 20 and the second pixels 3 corresponding to each other are the same, and when the stretchable display panel 100 is not stretched, each first pixel 20 is simultaneously displayed with the corresponding second pixel 3 as a whole, so that the overall display brightness of the stretchable display panel 100 can be ensured to be more uniform. When the stretchable display panel 100 is stretched, the number of columns of the second pixels 3 is the same as the number of columns of the first pixels 20, so that the pixel distribution on each place of the stretchable display panel 100 can be ensured to be uniform, the change of the number of pixels in a unit area can be ensured to be tiny, and the problem of poor display effect caused by different resolutions of the stretchable display panel 100 before and after stretching can be avoided.
Specifically, referring to fig. 9, the first pixels 20 of the same row may be connected together by a connection line, and the first pixels 20 of each row may be connected to a first gate driving circuit, the second pixels 3 of the same row may also be connected together by a connection line, and the second pixels 3 of each row may be connected to a second gate driving circuit, both of which are electrically connected to the control circuit 200, the first gate driving circuit being for scanning the first pixels 20 row by row in the column direction Y, the second gate driving circuit being for scanning the second pixels 3 row by row in the column direction Y, GA1 in fig. 9 representing the scanned first pixels 20 of the first row, gan representing the first pixels 20 of the nth row, gb1 representing the scanned second pixels 3 of the first row, gbn representing the scanned second pixels 3 of the nth row.
When the stretchable display panel 100 is not stretched and is in the display state, the control circuit 200 controls the first pixel 20 and the second pixel 3 to be simultaneously input in sequence, specifically, as shown in fig. 10, the first gate driving circuit scans the first pixel GA1 in the first row and the second gate driving circuit scans the second pixel GB1 in the first row at the same time, the control circuit 200 simultaneously inputs the same driving voltage to the scanned GA1 and GB1, then simultaneously scans the second row, and the control circuit 200 simultaneously inputs the same driving voltage to the scanned GA2 and GB2 until the last row is scanned. Thus, the first pixels 20 in the first row and the second pixels 3 in the first row are driven to emit light simultaneously, and the second pixels 3 have small areas when not stretched, so that the display effect is tiny, and the first pixels 20 and the second pixels are regarded as a whole to be displayed simultaneously, thereby not only not affecting the resolution, but also enhancing the display brightness of the display panel and being beneficial to improving the display effect.
When the stretchable display panel 100 is stretched in the column direction Y and is in the display state, the control circuit 200 controls the first pixel 20 and the second pixel 3 to sequentially input the driving voltages, specifically, as shown in fig. 11, the first gate driving circuit scans the first pixel GA1 in the first row first, the control circuit 200 inputs the driving voltages to the first pixel GA1 in the scanned first row, then the second gate driving circuit scans the second pixel GB1 in the first row, the control circuit 200 inputs the driving voltages to the second pixel GB1 in the scanned first row, then the first gate driving circuit scans the first pixel GA2 in the second row, the control circuit 200 sequentially inputs the driving voltages to the first pixel GA2 in the scanned second row in the order of GA1, GB1, GA2, GBn, GAn, so that the second pixel 3 in the same row is displayed separately from the first pixel 20, for example, the first pixel 20 has four columns, the second pixel 3 has four columns, the total pixel has four rows, each row has the first pixel 20 and the second pixel 3, after the second pixel 3 is stretched and enlarged, the area difference between the second pixel 3 and the area of the first pixel 20 is tiny, the pixels which can be displayed individually on the stretchable substrate 1 are equivalent to eight columns with four rows, the first pixel 20 in the first row is scanned, the second pixel 3 in the first row is scanned, the first pixel 20 in the second row is scanned, the second pixel 3 in the second row is scanned, the four rows of pixels are scanned in turn according to the scanning sequence, and the driving voltage is input, so that the pixels of the display panel can be uniformly distributed and displayed, the number of pixels in the unit area is not changed too much, the resolution difference of the stretchable display panel 100 before and after stretching is not large, the display effect of the stretchable display panel 100 is not affected.
In some embodiments, referring to fig. 7-8, along the row direction X, the size of each second pixel 3 is smaller than the size of the first pixel 20 in the same row; along the column direction Y, the size of each second pixel 3 is equal to the size of the first pixel 20 in the same row. In this way, the second pixels 3 can be made smaller in area when not stretched, and can be displayed as a whole with the first pixels 20, and the second pixels 3 can be made substantially the same area as the first pixels 20 after stretching, and the second pixels 3 can be displayed alone, thereby ensuring that the number of pixels per unit area is not significantly reduced, the difference in resolution before and after stretching of the stretchable display panel 100 is not large, and the display effect is not affected.
It should be noted that, since the stretchable direction of the stretchable display panel 100 is the row direction X, the size of the second pixel 3 in the row direction X may be increased by stretching, while the size of the second pixel 3 in the column direction Y is unchanged, so that the size of the second pixel 3 in the column direction Y needs to be set to be the same as the size of the first pixel 20 in the same row in the column direction Y, and the size of the second pixel 3 in the row direction X is set to be smaller than the size of the first pixel 20 in the same row in the row direction X, so that the size of the second pixel 3 in the row direction X becomes larger when the second pixel 3 is stretched, so that the area of the second pixel 3 is kept substantially the same as the area of the first pixel 20 in the same column.
In some embodiments, referring to fig. 8, the dimensions of each second pixel 3 in the same column of second pixels 3 in the row direction X are the same. In this way, the areas of the second pixels 3 in the same column after stretching are the same, so that the first pixels 20 and the second pixels 3 are uniformly distributed, and the display effect of the whole display panel is better.
In the second embodiment of the present application, the second pixel 3 located between two adjacent first pixels 20 is located in the middle of two adjacent first pixels 20 along the first direction. That is, along the row direction X, a column of second pixels 3 located between two adjacent columns is located at the middle position of two adjacent columns of first pixels 20, so that after the second pixels 3 are stretched, the distance between the second pixels 3 with the enlarged area and two adjacent first pixels 20 is equal, so that the first pixels 20 and the second pixels 3 are distributed more uniformly, which is beneficial to improving the display effect.
Example III
Referring to fig. 12, a third embodiment of the present application provides a display method of a display device, where the display device is a display device according to the first embodiment, and the display method includes:
s301, the state of the stretchable display panel 100 is acquired.
Specifically, the stretching degree of the stretchable substrate 1 may be sensed by the stretching sensing module 4 disposed on the stretchable substrate 1, and since the second pixels 3 are disposed on the stretchable substrate 1, the second pixels 3 may generate a stretching phenomenon along with the stretching of the stretchable substrate 1, and the stretching degree of the second pixels 3 may be obtained according to the stretching degree of the stretchable display substrate, thereby obtaining the state of the stretchable display panel 100. Note that, as long as the stretched area of the second pixel 3 does not reach the target area size, the state of the stretchable display panel 100 is described as being in the unstretched and display state, and when the stretched area of the second pixel 3 reaches the target area size, the state of the stretchable display panel 100 is described as being in the stretched and display state.
S302, when the stretchable display panel 100 is not stretched and is in a display state, the first pixels 20 and the second pixels 3 of two adjacent rows are controlled to input the driving voltage at the same timing.
S303, when the stretchable display panel 100 is stretched in the column direction Y and is in the display state, the driving voltages are controlled to be input to the first pixels 20 and the second pixels 3 of two adjacent rows in time sequence.
With the display method of the third embodiment of the present application, when the stretchable display panel 100 is not stretched in the display state, the area of the second pixel 3 is small, and the first pixel 20 and the second pixel 3 in the same pixel group 10 are displayed as a whole; when the stretchable display panel 100 is stretched in the first direction in the display state, the second pixels 3 are stretched, the area becomes large, and the first pixels 20 and the second pixels 3 in the same pixel group 10 can be displayed separately. In this way, although the distance between two adjacent first pixels 20 in the first direction becomes larger due to the stretching of the stretchable display panel 100, the compensation display of the second pixels 3 does not reduce the number of pixels that emit light per unit area too much, thereby reducing the phenomenon that the resolution of the stretchable display panel 100 decreases after the stretching in the first direction, thereby making the resolutions of the display panel approximate before and after the stretching, and reducing the screen display graininess.
