Description

Liquid crystal display panel and its pixel array structure

technical field

The invention relates to a liquid crystal display panel and its pixel array structure, in particular to a liquid crystal display panel with a plurality of protrusions and its pixel array structure.

Background technique

In today's society, multimedia technology is quite developed, and liquid crystal displays with superior characteristics such as high image quality, high space utilization, low power consumption, and no radiation have gradually become the mainstream of the market. Among them, a multi-domain vertically aligned (MVA) liquid crystal display is a common application of a liquid crystal display panel with a wide viewing angle technology.

The pixel structure of the multi-domain vertical alignment liquid crystal display panel will be described below. FIG. 1A , FIG. 1B and FIG. 1C show the pixel structures of three known multi-domain vertical alignment liquid crystal display panels. Please refer to FIG. 1A first, the pixel structure 100A includes an active device 110 and a pixel electrode 120 electrically connected to the active device 110 , wherein the active device 110 is electrically connected to the scan line 130 and the data line 140 . In addition, the pixel structure 100A further includes a protrusion 150 so that the liquid crystal molecules in the liquid crystal display panel exhibit multi-regional alignment, so as to achieve a wide viewing angle display effect. However, in the diagonal direction of the rectangular pixel electrode 120 , the distance d between the protrusion 150 and the edge of the pixel electrode 120 is relatively large. When the pixel structure 100A is driven, the degree of deformation of the electric field in the diagonal direction of the pixel electrode 120 is less obvious, and it is less easy to control the arrangement direction of the liquid crystal molecules. Therefore, if the liquid crystal molecules are disturbed, they are not easy to fall in the correct direction. For example, when the liquid crystal display panel is subjected to a single point of pressure so that the liquid crystal molecules are arranged chaotically, the liquid crystal molecules here often cannot return to the normal arrangement state in a short time.

In order to solve the above problems, slits extending along the diagonal direction may be formed on the pixel electrode 120 , as shown in FIG. 1B and FIG. 1C . Referring to FIG. 1B and FIG. 1C , the pixel electrode 120 of the pixel structure 100B has a slit 122 inside the pixel electrode 120 , and the pixel electrode 120 of the pixel structure 100C has a slit 124 at the edge of the pixel electrode 120 . The slit 122 and the slit 124 can enhance the electric field in the diagonal direction in the pixel electrode 120 to increase the reaction rate of the liquid crystal molecules.

Unfortunately, in the pixel structure 100B, although the formation of the slit 122 in the pixel electrode 120 is helpful to increase the reaction rate of the liquid crystal molecules, when the distance d is too large, the design of the slit 122 is prone to discontinuity of the liquid crystal molecules. , resulting in the uncertainty of the direction in which the liquid crystal molecules are tilted. In addition, although the design of the pixel structure 100C can increase the reaction rate of the liquid crystal molecules and help align the liquid crystal molecules in the correct direction of inversion, the design of the slit 124 will sacrifice more display area openings than the design of the slit 122 Rate. In short, none of these methods can improve the display effect of the multi-domain vertical alignment liquid crystal display panel while maintaining a good aperture ratio of the display area.

Detailed ways

Due to the design of the rectangular pixel electrodes in the known pixel structure, the liquid crystal molecules in the diagonal direction are not easy to react quickly and correctly. The present invention proposes a solution to this problem, wherein by disposing protrusions of different shapes between adjacent electrode blocks, the liquid crystal molecules tend to be arranged in a specific direction. In addition, the present invention also proposes to cut a single pixel electrode into a plurality of electrode blocks. The distance between the center of the electrode block and the edge area is small, which helps to increase the degree of electric field deformation from the edge of the electrode block to the center of the electrode block, and further achieves the effect of increasing the reaction rate of the liquid crystal molecules. The specific embodiments of the present invention will be listed below, but they are only for illustration and not intended to limit the present invention.

First Embodiment: FIG. 2A is a liquid crystal display panel according to a first embodiment of the present invention, and FIG. 2B is a schematic diagram of a pixel array structure of the liquid crystal display panel in FIG. 2A . Please refer to FIG. 2A , the liquid crystal display panel 200 includes a first substrate 210 , a second substrate 220 , a liquid crystal layer 230 and a pixel array structure 240A. The first substrate 210 includes a plurality of scan lines 212 and a plurality of data lines 214 , and the second substrate 220 includes a shared electrode 222 . In addition, the liquid crystal layer 230 is disposed between the first substrate 210 and the second substrate 220 .

Please refer to FIG. 2B , the pixel array structure 240A includes a plurality of pixel units 250 and a plurality of protrusions 260 . A plurality of pixel units 250 are arranged in an array and electrically connected to corresponding scan lines 212 and data lines 214 , and each pixel unit 250 includes an active device 252 and a pixel electrode 254 . The pixel electrode 254 has a plurality of electrode blocks and is electrically connected to the active device 252 . In FIG. 2B, the pixel electrode 254, for example, has an electrode block 254a and an electrode block 254b. In addition, the protrusion 260 is generally located in at least one boundary area B between a part of the electrode block 254a and the electrode block 254b. In other words, the protrusion 260 is located between the adjacent part of the electrode block 254a and the electrode block 254b. In detail, the boundary area B in this embodiment refers to the area between each electrode block 254a or electrode block 254b and the adjacent electrode block 254a or electrode block 254b. Furthermore, there is a boundary area B between any two left, right or up and down adjacent electrode blocks (254a, 254b), and any four adjacent electrode blocks 254a and electrode blocks 254b distributed in a rectangular shape There will also be a junction area B between them.

Please refer to FIG. 2A and FIG. 2B at the same time, each protrusion 260 located in the boundary area B between any four adjacent and rectangularly distributed electrode blocks 254a and electrode blocks 254b is, for example, adjacent to the electrode block 254a , the corner C of 254b, and the protrusion 260 is, for example, a plurality of conical protrusion structures. Further, the protrusion 260 is, for example, disposed above the data line 214 and the four adjacent electrode blocks 254 a, 254 b are, for example, surrounding the protrusion 260 . In addition, the protrusion 260 shown in FIG. 2B may be a conical protrusion structure, a square pyramid protrusion structure, a triangular pyramid protrusion structure or other polygonal cone protrusion structures.

According to the physical properties of the liquid crystal molecules, in the case of the protrusions 260 , the liquid crystal molecules will arrange themselves along the edges of the protrusions 260 . Therefore, after the liquid crystal display panel 200 is pressed at a single point, the originally scattered liquid crystal molecules will be arranged along the edges of the protrusions 260 according to their own physical properties. In this embodiment, the protrusion 260 corresponds to the corner C of each electrode block 254a, 254b, so as to affect the arrangement of the liquid crystal molecules from each corner C. Therefore, after the liquid crystal display panel 200 is subjected to a single point of pressure, the liquid crystal molecules originally arranged randomly can quickly recover the original arrangement state. Furthermore, the configuration of the bumps 260 can maintain a good display quality of the liquid crystal display panel 200 . On the other hand, the protrusion 260 is located on the scanning line 214, and its position is not the display area, so if the alignment of the liquid crystal molecules around the protrusion 260 is unclear, it will not affect the aperture ratio of the display area. Of course, the protrusion 260 can also be configured corresponding to other light-shielding metals or light-shielding layers, so as to maintain the display aperture ratio of the liquid crystal display panel.

Please continue to refer to FIG. 2A and FIG. 2B , generally speaking, when the liquid crystal display panel 200 is displaying images, the pixel electrodes 254 will be supplied with a voltage. The voltage difference between the first substrate 210 and the second substrate 220 is different where the pixel electrode 254 is located and the area outside the pixel electrode 254 . In other words, the electric field from the center of the pixel electrode 254 to the edge of the pixel electrode 254 is inconsistent, which helps to align the liquid crystal molecules of the liquid crystal layer 260 according to the direction of the electric field. If the area of the pixel electrode 254 is larger, the change rate of the electric field from the center of the pixel electrode 254 to the edge of the pixel electrode 254 is smaller, and the alignment of the liquid crystal molecules is less likely to be affected. Therefore, in the pixel unit 250 of the present invention, the pixel electrode 254 is divided into a plurality of blocks, so that the distance from the edge to the center of each electrode block 254 a and electrode block 254 b can be shortened. In this way, when the liquid crystal display panel 200 is displaying images, the rate of change of the electric field from the center to the edge of each electrode block 254a, 254b will increase to help control the alignment direction of the liquid crystal molecules and increase the reaction rate of the liquid crystal molecules.

It can be seen from FIG. 2B that each electrode block 254 a and electrode block 254 b has a plurality of side angles θ, and each side angle θ is approximately greater than or equal to 90° and less than 180°. For example, the side angle θ of the electrode block 254a is 90°, which constitutes a rectangle, and the side angle θ of the electrode block 254b is greater than 90°, such as to form a polygon. The polygonal design of the electrode block 254b is, for example, cutting off four corners of a rectangle, so that the distance from the center to the edge of the electrode block 254b in the direction of the diagonal of the rectangle is shortened. Therefore, the change rate of the electric field in the direction of the diagonal of the rectangle from the center to the edge of the electrode block 254b is increased. That is to say, the polygonal design of the electrode block 254b also helps to increase the reaction rate of the liquid crystal molecules. In the liquid crystal display panel 200 of this embodiment, the reaction rate of the liquid crystal molecules can be effectively improved and the liquid crystal molecules can be arranged correctly without disposing slits in each pixel electrode 254 . Therefore, the liquid crystal display panel 200 of the present invention can maintain good display quality without affecting the display aperture ratio.

In addition, the pixel electrode 254 also has a connection block 256 for connecting two adjacent electrode blocks 254 a and 254 b in the same pixel unit 250 . The electrode block 254a and the electrode block 254b may be transparent electrodes, reflective electrodes or a combination thereof. When the electrode block 254a and the electrode block 254b are both transparent electrodes, the connection block 256 can also be a transparent electrode, and when one of the electrode block 254a or the electrode block 254b is a transparent electrode, the other is a reflective electrode When , the connection block 256 can be a reflective electrode or a transparent electrode. In addition, when one of the electrode block 254a and the electrode block 254b is a reflective electrode, the active component 252 can be disposed under the reflective electrode, so as to increase the aperture ratio of the display area of the liquid crystal display panel 200 .

However, this embodiment does not limit the pixel electrode 254 to have only two electrode blocks, that is, the electrode block 254a and the electrode block 254b. For example, in the pixel array structure 240B shown in FIG. 2C , each pixel electrode 254 may have three electrode blocks, namely an electrode block 254 a , an electrode block 254 b and an electrode block 254 c . At the same time, there is a connection block 256 between every two adjacent electrode blocks (between the electrode block 254a and the electrode block 254b and between the electrode block 254b and the electrode block 254c) in each pixel electrode 254, so as to communicate with each other. connect. In other embodiments, each pixel unit 250 may also have more electrode blocks. When the pixel electrode 254 is divided into a plurality of electrode blocks, the distance from the center to the edge of each electrode block is smaller, and the rate of change of the electric field can be increased to increase the reaction rate of the liquid crystal molecules.

FIG. 2D is a liquid crystal display panel shown along the section line I-I' of FIG. 2A. Please refer to FIG. 2D , the liquid crystal display panel 200 further includes a plurality of protruding structures 224 disposed on the second substrate 220 . Meanwhile, the protruding structure 224 corresponds to the center of each electrode block 254a, for example. In fact, the protruding structure 224 is, for example, a protrusion, and the protruding structure 224 may correspond to the center of each electrode block. In the liquid crystal display panel 200, the protruding structure 224 can make the liquid crystal molecules in the electrode block 254a be aligned in multiple alignment directions to achieve the effect of wide viewing angle. At the same time, for a colorful display effect, the liquid crystal display panel 200 further includes a color filter film 226 disposed on the second substrate 220 .

In addition, in other embodiments, the shared electrode 222 can have multiple openings (not shown in the figure), and each opening (not shown in the figure) corresponds to the center of each electrode block 254a, 254b, that is, the protrusion in FIG. 2D The position of the structure 224 is replaced by an opening to replace the protruding structure 224 in FIG. 2D , so that the liquid crystal molecules in the electrode block 254 a exhibit multi-domain alignment to achieve a wide viewing angle display effect. More specifically, a plurality of spacers (not shown in the figure) may also be disposed in the liquid crystal display panel 200 to maintain the distance between the first substrate 210 and the second substrate 220 , that is, the cavity gap. The spacers (not shown in the figure) are, for example, spherical spacers or photoresist spacers, and the spacers, for example, can be disposed above the scan lines 212 or the data lines 214 to avoid affecting the aperture ratio. In addition, when one of the electrode blocks 254a, 254b is a reflective electrode, the spacer can also be disposed above the reflective electrode.

Embodiment 2: Of course, the liquid crystal display panel proposed by the present invention is not limited to having the pixel array structure described in the above embodiments. Actually, the pixel array structure applied to the liquid crystal display panel of the present invention can also have many different types. FIG. 3 is a pixel array structure of the second embodiment of the present invention. Please refer to FIG. 3 , the pixel array structure 340 of this embodiment is substantially the same as the pixel array structure 240A of the first embodiment. The difference is that in the pixel array structure 340, the protrusions 360 corresponding to the corners C of the electrode blocks 254a and 254b are a plurality of cross protruding structures.

As shown in FIG. 3 , the protrusion 360 is, for example, located between four adjacent electrode blocks 254 a and 254 b arranged in a rectangular shape, and each cross-shaped protrusion structure has a vertical portion parallel to the data line 214 360a and a horizontal portion 360b perpendicular to the data line 214 . The vertical portion 360a and the horizontal portion 360b are, for example, extending from each corner C to the boundary area B between two adjacent electrode blocks 254a and 254b. The vertical portion 360 a and the horizontal portion 360 b can make the liquid crystal molecules arrange along the periphery of the protrusion 360 and pour toward the center of each electrode block 254 a and electrode block 254 b. Therefore, when the pixel array structure 340 is applied to the liquid crystal display panel, the protrusions 360 of the cross-shaped protrusion structure help to influence the arrangement direction of the liquid crystal molecules. In other words, the application of the pixel array structure 340 can increase the reaction rate of the liquid crystal molecules in the liquid crystal display panel, and when the liquid crystal molecules are disturbed and scattered, the liquid crystal molecules will be affected by the protrusions 360 and quickly return to the original alignment direction. In addition, in the pixel array structure 360, the electrode block 254a and the electrode block 254b can be rectangular or polygonal according to different design requirements. Furthermore, the pixel electrode 254 may also have three or more than three electrode blocks.

Embodiment 3: In the present invention, the pixel electrode is divided into a plurality of electrode blocks. In order to adjust the tilting direction of the liquid crystal molecules on the boundary area between the electrode block and the electrode block of the same pixel electrode, this embodiment proposes another A raised configuration.

FIG. 4A is a schematic diagram of a pixel array structure according to a third embodiment of the present invention. Please refer to FIG. 4A , the pixel array structure 440A is substantially the same as the pixel structure 240A, except that in each pixel unit 450 of the pixel array structure 440A, the protrusion 460A is, for example, located at the border area between two adjacent electrode blocks 454a and electrode blocks 454b B central. In addition, the scan line 212 corresponding to each pixel unit 450 is located between two adjacent electrode blocks 454 a and 454 b of each pixel unit 450 , for example. Wherein, the electrode block 454a is, for example, a reflective electrode, and the electrode block 454b is, for example, a transparent electrode.

FIG. 4B is a cross-sectional view of the pixel unit 450 in FIG. 4A along the extension direction of the scan line 212, and FIG. 4C is a cross-sectional view of the pixel unit 450 in FIG. 4A along the section line II-II'. Please refer to FIG. 4B and FIG. 4C at the same time. In the same pixel unit 450 , the protrusion 460A between two adjacent electrode blocks 454 a and 454 b is, for example, a cone-shaped protrusion structure. In addition, the connection electrode 456 covers, for example, the protrusion 460A, and the connection electrode 456 is, for example, a transparent electrode. In addition, the common electrode 216 is arranged parallel to the scan line 212 .

When the pixel unit 450 is applied to a liquid crystal display panel, the liquid crystal molecules will be arranged around the protrusion 460A. Therefore, the liquid crystal molecules located around the protrusion 460A and close to the electrode block 454a will tilt towards the center of the electrode block 454a, and the liquid crystal molecules close to the electrode block 454b will tilt towards the center of the electrode block 454b. In other words, the protrusion 460A can make the liquid crystal molecules around the connection electrode 456 tend to fall toward the center of the electrode block 454a or the electrode block 454b, thereby helping to maintain the display quality of the liquid crystal display panel.

In other embodiments, if the pixel array structure 440A is applied to a liquid crystal display panel, a plurality of common electrodes 216 may also be arranged on the pixel array substrate, and each common electrode 216 is correspondingly arranged on two adjacent electrodes of each pixel unit 450 Between the block 454a and the electrode block 454b. That is to say, in other embodiments, the common electrode 216 can be disposed under the protrusion 460A and parallel to the scan line 212 , for example. In addition, the liquid crystal molecules will be arranged along the protrusion 460A, which may cause light leakage at the position of the protrusion 460A. Therefore, the connection block 456 on the protrusion 460A may be a reflective electrode. In other words, the electrode block 454 a , the electrode block 454 b and the connection block 456 may all be, for example, reflective electrodes, transparent electrodes, or a combination of reflective electrodes and transparent electrodes.

In addition, the protrusion 460A located between two adjacent electrode blocks 254 a and 254 b in the same pixel unit 450 is not limited to a tapered protrusion structure. FIG. 5 and FIG. 6 are schematic diagrams of other two kinds of protrusions according to the third embodiment of the present invention. Please refer to FIG. 5 and FIG. 6 , in the pixel array structure 440B and the pixel array structure 440C, the protrusions 460B and 460C may be protrusions presenting a stripe structure. The protrusion 460B is, for example, located in the pixel unit 450 and above the scan line 212 but does not intersect the data line 214 , while the convex protrusion 460C is, for example, crossing a plurality of data lines 214 and spanning a plurality of pixel units 450 . Here, the protrusions 460B, the rib-shaped protrusions 460C and the tapered protrusions 460A also have the function of assisting the arrangement of the liquid crystal molecules. Furthermore, the protrusions 460A, 460B, and 460C of this embodiment can be configured in the same pixel array structure as the protrusions 260 , 360 described in the first and second embodiments.

In summary, the pixel array structure and the liquid crystal display panel of the present invention have at least the following advantages. In the liquid crystal display panel and the pixel array structure of the present invention, the configuration of the protrusions helps to guide the arrangement direction of the liquid crystal molecules, and enables the liquid crystal molecules to quickly restore the correct arrangement direction after being disturbed. At the same time, the protrusion is located in at least one boundary region of the electrode block to prevent the aperture ratio of the display area of the liquid crystal display panel from being affected. In addition, the present invention uses a combination of multiple electrode blocks to form a pixel electrode, which can shorten the distance from the edge of the electrode to the center, and increase the rate of change of the electric field to increase the reaction rate of liquid crystal molecules. Therefore, after the liquid crystal display panel of the present invention is subjected to a single point of pressure, the liquid crystal molecules can quickly return to a normal alignment state so that the liquid crystal display panel can maintain good display quality.

Certainly, the present invention also can have other multiple embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes All changes and modifications should belong to the scope of protection of the appended claims of the present invention.
