Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Fig. 1 is a schematic diagram of a display device 100 according to an embodiment of the invention. The display device 100 includes a display panel 110 and a driving control circuit 120. The display panel 110 may include a plurality of pixels P (1,1) to P (M, N). The driving control circuit 120 may be coupled to the display panel 110.
In some embodiments, the pixels P (1,1) to P (M, N) may include a plurality of Light Emitting Diodes (LEDs), a plurality of Organic Light Emitting Diodes (OLEDs), a plurality of Micro Light Emitting diodes (Micro Light Emitting diodes), or a plurality of sub-millimeter Light Emitting diodes (Mini Light Emitting diodes), and the driving control circuit 120 may individually drive the pixels P (1,1) to P (M, N), i.e., individually drive the pixels P (1,1) to P (M, N).
In some embodiments, the display device 100 can drive the display panel 110 at different frame rates in different modes. For example, in the first mode, the driving control circuit 120 can individually drive the pixels P (1,1) to P (M, N) in each frame period, and in the second mode, the driving control circuit 120 can individually drive a part of the pixels in the pixel driving control circuit 120 in each frame period. Since the driving control circuit 120 drives only a part of the pixels P (1,1) to P (M, N) in the second mode, not all of the pixels P (1,1) to P (M, N), the length of each frame period in the first mode can be greater than that in the second mode with the pixel clock (pixel clock) kept constant. That is, the display device 100 can drive the display panel 110 with a lower frame period in the second mode, i.e., the display device 100 will have a higher frame rate in the second mode.
FIG. 2 is a diagram illustrating an exemplary usage scenario of the display panel 110 in the second mode according to the present invention. In fig. 2, the pixels P (1,1) to P (M, N) may be divided into a plurality of first blocks B1, and the display device 100 may drive at least one pixel in each of the first blocks B1 in the second mode. In some embodiments, each of the first blocks B1 may have the same size and shape, and the driving control circuit 120 may drive the pixels located at different positions in each of the first blocks B1 in different frame periods in the second mode.
For example, in fig. 2, each first block B1 may include four pixels. In the second mode, the driving control circuit 120 may drive the pixel PA located at the upper left corner in each first block B1 in one frame period, drive the pixel PB located at the upper right corner in each first block B1 in the next frame period, and so on, sequentially drive the pixel PC located at the lower left corner in each first block B1 and the pixel PD located at the lower right corner in each first block B1 in the following two frame periods, and so on, alternately cycle.
That is, in the second mode, the pixels P (1,1) to P (M, N) may be divided into a plurality of sections, and the drive control circuit 120 may drive the pixels of the respective sections in different frame periods in a divided manner. Thus, the frame period can be shortened, and the frame rate can be improved. In the present embodiment, since the driving control circuit 120 only needs to drive one quarter of the pixels P (1,1) to P (M, N) in each frame period in the second mode, the frame period in the second mode can be shortened by one quarter compared to the frame period in the first mode, so that the frame rate is increased by four times.
In some embodiments, the driving control circuit 120 can drive the pixels P (1,1) to P (M, N) by active Addressing (AM), so that the driving control circuit 120 can individually control the pixels P (1,1) to P (M, N) by selecting specific gate lines and data lines.
In addition, the present invention is not limited to dividing the pixels P (1,1) to P (M, N) into a plurality of 2 × 2 blocks. In some other embodiments, the designer may adjust the size and shape of the first block B1 according to the system requirements and the frame rate desired to be achieved. In addition, the present invention is not limited to dividing the pixels P (1,1) to P (M, N) into blocks with the same size and shape, and in some other embodiments, the designer may divide the pixels P (1,1) to P (M, N) into blocks with different sizes and/or shapes, and drive at least one pixel in each block in each frame period.
Furthermore, in some embodiments, the driving control circuit 120 may also drive the plurality of pixels in each of the first blocks B1 in each frame period of the second mode. For example, in the second mode, the driving control circuit 120 may drive two pixels in each first block B1 in one frame period, and drive another two pixels in each first block B1 in the next frame period, and so on in alternating cycles. For example, the driving control circuit 120 may drive the pixel PA located at the upper left corner and the pixel PD located at the lower right corner in each first block B1, and drive the pixel PC located at the lower left corner and the pixel PB located at the upper right corner in each first block B1 in the next frame period. However, the present invention does not limit the order in which the driving control circuit 120 drives the pixels of the first block B1.
In this case, since the driving control circuit 120 drives half of the pixels P (1,1) to P (M, N) in each frame period in the second mode, the frame period in the second mode can be shortened by half and the frame rate can be increased by two times compared with the frame period in the first mode.
In some embodiments, the display device 100 may have more modes to provide more frame rate options to the user. FIG. 3 is a diagram illustrating an exemplary usage scenario of the display panel 110 in a third mode according to the present invention. In fig. 3, the pixels P (1,1) to P (M, N) are divided into a plurality of second blocks B2, and the display device 100 can drive at least one pixel in each of the second blocks B2 in the third mode. In some embodiments, the second block B2 and the first block B1 may include different numbers of pixels. For example, in fig. 3, each second block B2 may include 3x2 pixels. In some embodiments, the driving control circuit 120 can sequentially drive the six pixels in each of the second blocks B2 in six frame periods, so that in the third mode, the driving control circuit 120 can drive one sixth of the pixels P (1,1) to P (M, N) in each frame period, and thus the frame rate can be reduced by one sixth compared to the frame period of the first mode, thereby increasing the frame rate by six times.
However, the present invention is not limited to the case where the driving control circuit 120 can drive only one pixel in the second block B2 in each frame period. In some other embodiments, the driving control circuit 120 may drive two pixels in each of the second blocks B2 in each frame period. In this way, in the third mode, the driving control circuit 120 can drive one-third of the pixels P (1,1) to P (M, N) in each frame period, so that the frame period of the third mode can be shortened by one-third compared with the frame period of the first mode, and the frame rate can be increased by three times. That is, the display device 100 can adjust the driving timing of the pixels P (1,1) to P (M, N) according to the frame rate to be displayed, and thus can display images at different frame rates flexibly.
Fig. 4 is a schematic diagram of a display device 200 according to another embodiment of the invention. The display device 200 may have a similar structure and may operate according to similar principles as the display device 100. However, the display device 200 may further include a screen menu driving control circuit 230. The screen menu driving control circuit 230 can display a function menu, such as an on-screen display (OSD), through the display panel 110. In some embodiments, the menu may comprise a plurality of frame rate options. In this way, the user can select the desired frame rate in the function menu, and the driving control circuit 120 can enter the corresponding mode according to the frame rate selected by the user. For example, when a first frame rate in the menu is selected, the display device 200 may enter the first mode, and when a second frame rate in the menu is selected, the display device 200 may enter the second mode.
Fig. 5 is a schematic diagram of a display device 300 according to another embodiment of the invention. The display device 300 may include a display panel 310 and a driving control circuit 320. The display panel 310 may include a plurality of pixels P (1,1) to P (M, N). The driving control circuit 320 may be coupled to the display panel 310. In some embodiments, the driving control circuit 320 may drive the display panel 310 at different frame rates in different modes. For example, the driving control circuit 320 may individually drive the pixels P (1,1) to P (M, N) in each frame period of the first mode. However, in each frame period of the second mode, the driving control circuit 320 may drive only the pixels in the first specific block SB1 in the display panel 310. In fig. 5, the first specific block SB1 may be square, and the number of pixels in the first specific block SB1 is less than the number of pixels P (1,1) to P (M, N) in the display panel 310. The plurality of pixels include a plurality of light emitting diodes, a plurality of organic light emitting diodes, a plurality of micro light emitting diodes or a plurality of sub-millimeter light emitting diodes.
Since the driving control circuit 320 drives only a part of the pixels P (1,1) to P (M, N) in the second mode, not all of the pixels P (1,1) to P (M, N), the length of each frame period in the first mode can be greater than the length of each second frame period in the second mode with the pixel clock (pixel clock) kept constant. That is, the display device 300 can drive the display panel 110 with a lower frame period in the second mode, i.e., the display device 300 has a higher frame rate in the second mode.
In addition, in some embodiments, the driving control circuit 320 may also individually drive the pixels in the second specific block SB2 in the display panel 310 in each frame period in the third mode. In fig. 5, the second specific block SB2 is also square and partially overlaps the first specific block SB1, however, the shape and position of the first specific block SB1 and the second specific block SB2 are not limited in the present invention. However, since the first specific block SB1 and the second specific block SB2 may include different numbers of pixels, the frame period of the third mode may be different from that of the second mode, so that more frame rate options are provided for the user.
In the embodiment of fig. 5, the display device 300 may further include a screen menu driving controller 330 and a display specification control circuit 340. The screen menu driving controller 330 may be coupled to the driving control circuit 320, and may control the driving control circuit 320 to display the function menu on the display panel 310. The function menu may comprise a plurality of frame rate options. In this way, the user can select the desired frame rate in the function menu, and the driving control circuit 320 can enter the corresponding mode according to the frame rate selected by the user. For example, when a first frame rate in the menu is selected, the display device 300 may enter the first mode, and when a second frame rate in the menu is selected, the display device 300 may enter the second mode.
In addition, in some embodiments, the image data displayed by the display device 300 is provided by an external data source system DS, such as but not limited to a computer. Therefore, when the display device 300 switches between different modes, the display device 300 can also notify the data source system DS of the corresponding display range change, so that the data source system DS can correspondingly update the image data to meet the requirement of the current mode.
For example, the Display specification control circuit 340 may obtain Extended Display Identification Data (EDID) Data of the Display panel 310. In some embodiments, when the second frame rate in the function menu is selected, the driving control circuit 320 may output an update signal to the display specification control circuit 340, and the display specification control circuit 340 may obtain the updated extended display capability identification data of the display panel 310 according to the update signal. In this way, the display specification control circuit 340 can transmit the updated extended display capability identification data to the data source system DS to change the image specification of the data source system DS when outputting the image. For example, if the display panel 310 includes 3840 × 2160 pixels, i.e., N is 3840 and M is 2160, in the first mode, the data source system DS outputs 3840 × 2160 pixels in each frame period. However, if the first specific block SB1 only includes 1920 × 1080 pixels, the data source system DS also outputs 1920 × 1080 pixels per frame period correspondingly in the second mode.
In this way, the display device 300 can flexibly adjust the frame rate when displaying the image according to the user's requirement.
The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
