Problems solved by technology

[0004] When the existing anti-peep display is displayed at a narrow viewing angle, the anti-peep display not only has a horizontal electric field that drives the liquid crystal molecules to rotate in the horizontal plane, but also has a vertical electric field, so that part of the liquid crystal molecules are tilted, from the upper right side and the right side of the anti-peep display. There will be a gray scale difference in the picture viewed from the lower side, but there will be no gray scale difference in the picture viewed from the upper left side and the lower left side of the anti-peeping display, which will cause the problem of gray scale inversion when the anti-peeping display is displayed at a narrow viewing angle

[0024] figure 1 is a schematic structural diagram of the display panel according to the first embodiment of the present invention. like figure 1 As shown, the display panel 100 of the present invention is an IPS or FFS liquid crystal display panel, that is, the common electrode 14 and the pixel electrode 16 are formed on the same substrate (ie, a thin film transistor array substrate). The IPS type display panel 100 will be described below. In this embodiment, the display panel 100 includes a plurality of pixels 101 arranged in a matrix, each pixel 101 includes a first sub-pixel 101a and a second sub-pixel 101b, and the first sub-pixel 101a and the second sub-pixel 101b are vertically symmetrical but not limited thereto, the first sub-pixel 101a and the second sub-pixel 101b can also be arranged asymmetrically. It is worth mentioning that the pixel 101 is a point on the display panel 100 and any area or position corresponding to the point along the thickness direction of the...

[0035] Figure 5 is a schematic front view of the array substrate according to the second embodiment of the present invention. like Figure 5 As shown, the structure of the display panel 100 of this embodiment is substantially the same as that of the display panel 100 of the first embodiment, the difference lies in the partial structure of the array substrate 10 .

[0036] Specifically, in this embodiment, the first pixel region 103a and the second pixel region 103b are arranged adjacent to each other up and down, such as Figure 5 As shown, the first pixel area 103 a is located in the middle area of ​​the pixel 101 , and the second pixel area 103 b is located in the area of ​​the pixel 101 close to the two scan lines 17 . In order to realize multiple different birefringence in the same pixel 101, there is a first distance L1 between two adjacent electrode strips 164 in the first pixel region 103a, and a first distance L1 between the two adjacent electrode strips 164 in the ...

[0038] The present invention also relates to a display device, which includes the above-mentioned display panel 100 and a backlight module, the backlight module is disposed under the display panel 100 , and the backlight module is used to provide a backlight for the display panel 100 . For the structure of the display device, please refer to the prior art, which will not be repeated here.

[0039] Each pixel 101 of the display panel 100 of the present invention includes a first pixel area 103a and a second pixel area 103b. When the display panel 100 performs narrow viewing angle display, the birefringence of the liquid crystal in the first pixel area 103a is different from that of the second pixel area 103b. The birefringence of the liquid crystals is different. Since each pixel 101 of the display panel 100 of the present invention has multiple different birefringence indices, and multiple different birefringence indices can compensate each other, when the display panel 100 pe...

Abstract

The invention discloses a display panel. The display panel comprises multiple pixels which are distributed in a matrix mode, and each pixel comprises a first pixel area and a second pixel area. When the display panel conducts narrow-view-angle displaying, the liquid crystal birefringence rate in each first pixel area and the liquid crystal birefringence rate in each second pixel area are different. When the display panel conducts narrow-view-angle displaying, gray-scale inversion can be effectively improved. The invention further relates to a display device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display panel and a display device. Background technique [0002] Liquid crystal display (liquid crystal display, LCD) has the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and occupies a dominant position in the field of flat panel display. [0003] With the continuous advancement of liquid crystal display technology, the viewing angle of the display has been expanded from about 120° to more than 160°. While enjoying the visual experience brought by the large viewing angle, people also hope to effectively protect commercial secrets and personal privacy. Avoid commercial loss or embarrassment caused by information leakage on the screen. Therefore, in addition to the requirement for a wide viewing angle, it is also required in many occasions that the disp...
