Description

Liquid crystal display with different curved wires and light-shielding patterns

technical field

The invention relates to a liquid crystal display, and in particular to a liquid crystal display with different bending degrees of wires and corresponding light-shielding patterns.

Background technique

Electronic products with display panels have become an indispensable necessity for modern people, whether in work, study, or personal leisure and entertainment, including smart phones (Smart Phone), tablet computers (Pad), notebook computers (Notebook ), Monitor (Monitor) to TV (TV) and many other related products. Among them, liquid crystal display panels are the most common. Since liquid crystal display panels are more compact, lighter, portable, cheaper, more reliable, and more comfortable for the eyes in most applications, they have widely replaced cathode ray tube displays (CRT), Become the most widely used display, while providing a variety of options including size, shape, resolution and more.

In addition to paying attention to the details of the manufacturing process, such as precise patterning of the conductive layer to avoid disconnection, the manufactured panel also needs to have good and stable display quality.

Contents of the invention

The purpose of the present invention is to provide a liquid crystal display, through the design of the special shape of the wire, such as the electrode, so that the curved part of the electrode and the corresponding light-shielding pattern presents different degrees of curvature, for example, the two sides of the curved part of the electrode have different radians. When the voltage is applied to the liquid crystal display, it can increase the amount of rotation of the liquid crystal on the flat side of the corresponding electrode bending portion, and relatively increase its brightness, thereby improving the display quality of the applied product. Although the rotation amount of the liquid crystal molecules on the flat side of the liquid crystal display panel is increased, thereby relatively improving its brightness, the horizontal field component will make the inversion of the liquid crystal inconsistent, so the pressing stability will be poor. If the area with poor pressing stability in the liquid crystal display panel is touched by an external force, the area of dark lines will easily become larger, and the rotation angle of the liquid crystal molecules in this area is fixed and is not controlled by the electric field. Therefore, the light-shielding pattern can be used to cover the regions with poor pressing stability during actual fabrication.

According to the present invention, a liquid crystal display is proposed, comprising a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer disposed between the first substrate and the second substrate, and a liquid crystal layer located between the first substrate and the second substrate. A light-shielding pattern between the two substrates. The second substrate includes a plurality of wires. Wherein, one of the wires is projected onto the light-shielding pattern in a first direction to generate a projected line segment, wherein the projected line segment is located in the light-shielding pattern, and the projected line segment includes a curved portion and two extension portions connecting two ends of the curved portion. Wherein, the distance in a second direction between the edge of the light-shielding pattern and the curved portion is not equal to the distance in the second direction between the edge of the light-shielding pattern and one of the two extensions, wherein the first direction is perpendicular to second direction.

Detailed ways

Embodiments of the present invention provide a liquid crystal display. The wires, such as electrodes, are specially designed so that opposite sides of the curved portion of the electrode present different degrees of curvature. In one embodiment, the curvature of the concave side of a curved portion of the electrode is gentler than that of the opposite convex side, such as presenting an arc curve. When a voltage is applied to the liquid crystal display, the amount of rotation of the liquid crystal corresponding to the concave side of the curved portion of the electrode can be increased, thereby increasing its brightness relatively. The disclosed embodiments can be applied in a wide range, for example, they can be applied to a liquid crystal display in a fringe field switching (FFS) display mode.

The implementation will be described in detail below with reference to the accompanying drawings. It should be noted that the structures and contents provided in the embodiments are for illustration purposes only, and the protection scope of the present invention is not limited to the above-mentioned aspects. In the embodiments, the same or similar symbols are used to indicate the same or similar parts. It should be noted that not all possible embodiments of the present invention are shown. Changes and modifications can be made to the structure without departing from the spirit and scope of the present invention to meet the needs of practical applications. Therefore, other implementation aspects not proposed in the present invention may also be applicable. Furthermore, the drawings are simplified to clearly illustrate the content of the embodiments, and the size ratios in the drawings are not drawn according to the actual product scale. Therefore, the specification and illustrations are only used to describe the embodiments, not to limit the protection scope of the present invention.

FIG. 1 is a top view of a liquid crystal display in a fringe field switching (FFS) display mode according to an embodiment of the present invention. FIG. 2 is a schematic cross-sectional view of a liquid crystal display along line A-A in FIG. 1 , which only shows the relative positions of the data line DL, the pixel electrode PE, the common electrode Com, and the light-shielding pattern BM. Please refer to Figure 1 and Figure 2 at the same time. Wherein, the common electrode Com (such as patterned ITO) is disposed above the pixel electrode PE, and an insulating layer IL is disposed between the common electrode Com and the pixel electrode PE, and an interlayer dielectric layer is further disposed below the pixel electrode PE. (interlayerdielectric) IDL, and there is a lower substrate S1 under the interlayer dielectric layer. The pixel electrode PE is a piece of electrode, and the common electrode Com is a patterned electrode. The electric field generated between the common electrode Com and the edge of the pixel electrode PE can be used to drive the liquid crystal molecules LC to rotate. A light-shielding pattern is disposed on an upper substrate S2, and the position of the light-shielding pattern (such as a black matrix) BM is located directly above the data line DL. In addition to separating color resists of different colors, the light-shielding pattern BM also has a DL for shielding the data line effect. In this embodiment, the architecture shown in FIG. 2 is one of the fringe electric field switching display modes. The difference between the other architecture and the first architecture is that the pixel electrode PE is arranged above the common electrode Com, and the pixel electrode PE It is a patterned electrode, and the common electrode Com is a piece of electrode. A planarization layer and an interlayer dielectric layer IDL can be disposed under the pixel electrode PE. It should be noted that the various implementation aspects proposed in the present invention can be applied to any structure of the fringe electric field switching display mode.

In the first architecture shown in Figure 2, the design of the shape of the common electrode Com mainly takes into account the optical effects produced by it. The shape of a common electrode Com proposed by the present invention is shown in Figure 1, which corresponds to multiple The common electrode of the pixel. The patterned common electrode Com has a plurality of electrode branches, each electrode branch has a curved portion, and the curved portion includes two opposite concave sides and convex sides. The curved portion divides each sub-pixel into two regions where the liquid crystal molecules are arranged in two different directions, thus providing the effect of wide viewing angle. However, since the bent portion is at the intersection of the regions where the liquid crystal molecules are aligned in different directions, the orientation of the liquid crystal molecules in the region near the bent portion is more disordered than in other regions. Therefore, after the pixels are turned on, dark lines tend to occur in the area near the bent portion.

According to the above, the present invention conducts multiple sets of simulation tests on different embodiments to observe the influence of the electrode structure design of the embodiments on the brightness distribution change. One set of simulation results is listed below. It is worth noting that the electrode structure design of this group of simulation tests and the gray value of the simulation results are for reference and illustration only, and are not used to limit the applicable electrode structure of the present invention, nor can the application of the present invention achieve brightness enhancement best effect.

Please refer to FIG. 3A to FIG. 3C and Table 1. FIG. 3A is a schematic diagram of a common electrode (Com) structure of a first embodiment in a simulation test. FIG. 3B is a schematic diagram of a common electrode structure according to a second embodiment of the present invention in a simulation test. FIG. 3C is a gray scale distribution diagram obtained by the common electrode structure according to the first embodiment and the second embodiment.

In the simulation test, the relative position A is, for example, taken from a position of 49.25 μm relative to a reference point, the relative position B is, for example, taken from a position of 56.5 μm relative to a reference point, and the relative position C is, for example, taken from a position of 64 μm relative to a reference point The relative position D is, for example, taken from the position of 71.25 μm relative to the reference point.

As shown in FIG. 3B , in the common electrode structure of the second embodiment, the curvature of the concave side of the curved portion (such as relative positions A˜D) is gentler than that of the convex side. In actual application, the concave side of the electrode bending portion may include a vertical line segment. As shown in FIG. 3A , in the common electrode structure of the first embodiment, the concave side of the curved portion presents the same sharp lines as the convex side. Relative positions 1 to 4 represent dark lines with extremely low brightness, while relative positions A to D represent bright lines with high brightness. The gray scale distribution of both common electrode structures is shown in Fig. 3C.

Table 1

Location Gray scale of the first embodiment The gray scale of the second embodiment increase percentage A 0.193 0.232 twenty one% B 0.195 0.280 44% C 0.175 0.263 50% D. 0.169 0.249 47%

According to the simulation test results, as shown in Figure 3C and Table 1, it can be clearly found that at the same relative positions A to D, compared with the common electrode structure of the first embodiment, the gray corresponding to the common electrode structure of the second embodiment Brightness/brightness values have indeed improved significantly. In this simulation it increases by at least 20% (relative position A) and can be as high as 50% (relative position C). It can be seen that, as in the design of the second embodiment, if the curvature of the concave side of the curved portion is designed to be gentler than the curvature of the convex side, the brightness value corresponding to the common electrode structure can be increased.

When applying the embodiment of the present invention, it is preferable to adjust other elements accordingly according to the design of the electrode structure used in practice. For example, in an application example, in order to improve brightness, the electrode structure is designed so that the concave side of the curved part has a relatively gentle arc curve. The arc curve of the electrode behind the curved part will cause an increase in the horizontal field component, although the liquid crystal display panel The amount of rotation of the liquid crystal molecules in this region increases, thereby relatively improving its brightness, but the horizontal field component will make the inversion of the liquid crystal inconsistent, so the pressing stability will be poor. If the area with poor pressing stability in the liquid crystal display panel is touched by an external force, the area of dark lines will easily become larger, and the rotation angle of the liquid crystal molecules in this area is fixed and is not controlled by the electric field. Therefore, the light-shielding pattern can be used to cover the regions with poor pressing stability during actual fabrication.

FIG. 4 is a schematic diagram of the circled area in FIG. 1 . As shown in Figure 4, when the electrode structure of the embodiment shown in Figure 3B is applied to the common electrode Com, the concave side of the curved part of the common electrode Com has a relatively gentle arc curve to improve brightness, but there may also be pressure Regions with poor stability (circled in Figure 4) are generated. This area can be covered by the appropriate design of the light-shielding pattern (such as the black matrix BM), for example, the concave side of the ITO common electrode Com corresponding to this area is retracted in the light-shielding pattern BM, so as to reduce the effect of the dark pattern area on the display Impact.

Similarly, the wire 21 may also include a scan line, which is projected onto the first substrate 10 in the first direction D1 to generate a projected line segment, and the projected line segment extends along a second direction D2.
