Problems solved by technology

[0010] It can be seen that the anti-peeping technology of the existing display often needs to sacrifice some of the original characteristics, such as display quality, optical characteristics, thickness and weight, etc., while achieving the anti-peeping effect. Therefore, the existing anti-peeping technology still has room for improvement

no. 1 approach

[0099] figure 1 A schematic diagram showing a display panel in a wide viewing angle display mode according to the first embodiment of the present invention. figure 2 show figure 1 The schematic diagram of the display panel in the narrow viewing angle display mode. Such as figure 1 As shown, the display panel of this embodiment includes a first display area D1 (that is, figure 1 upper right display area and lower left display area) and the second display area D2 (that is, figure 1 upper left display area and lower right display area). The first display area D1 and the second display area D2 respectively have a plurality of pixels 100 . Each pixel 100 includes a first sub-pixel 110 and a second sub-pixel 120 . The second sub-pixel 120 is adjacent to the first sub-pixel 110 . Of course, in practical applications, the layout (layout) of the first display area D1 and the second display area D2 of the display panel is not figure 2 and figure 2 As shown only.

no. 2 approach

[0122] Figure 5 A top view of a pixel 100 according to a second embodiment of the present invention is shown. The difference between this embodiment and the first embodiment is that in this embodiment, only the first branch pixel electrodes 113 of the first sub-pixel 110 are designed to be misaligned.

[0123] As for other related structures, driving methods and operation details, they are the same as those of the first embodiment, so they will not be repeated here.

no. 3 approach

[0125] Figure 6 A top view of a pixel 100 according to a third embodiment of the present invention is shown. The difference between this embodiment and the first embodiment is that in this embodiment, the first branch pixel electrodes 113 of the first sub-pixel 110 are symmetrically arranged on both sides of the first trunk pixel electrode 112 . That is to say, the first branch pixel electrodes 113 in this embodiment are not designed to be misplaced, but only the first opaque connection lines 115 are at least partially overlapped under the first trunk pixel electrodes 112 .

[0126] As for other related structures, driving methods and operation details, they are the same as those of the first embodiment, so they will not be repeated here.

Abstract

The invention provides a display panel. The display panel includes a first and a second display zone provided with a plurality of pixels respectively. Each pixel includes a first sub pixel and a second sub pixel. The first sub pixel includes a first trunk pixel electrode and a plurality of first branch pixel electrodes. The first branch pixel electrodes connect and are arranged on two side of the first trunk pixel electrode electrically. When the display panel is in a narrow view angle display mode and the first and the second display zone display a facing luminance respectively, the driving voltage of the first sub pixel in the first display zone is higher than the driving voltage of the second sub pixel in the first display zone and the first sub pixel and the second sub pixel in the second display zone, and the driving voltage of the second sub pixel in the first display zone is lower than driving voltage of the first sub pixel in the first display zone and the first sub pixel and the second sub pixel in the second display zone. By utilizing the branch pixel electrodes and opaque connection circuits arranged in a staggering manner, the side-looking luminance of the sub pixel can be reduced, and the anti-peeping effect of the panel can be improved.

Description

technical field [0001] The invention relates to a display panel. Background technique [0002] Generally speaking, in order to provide the picture to multiple viewers, the display usually has a display effect with a wide viewing angle, but at certain times or occasions, such as when reading confidential information or entering a password, the display effect with a wide viewing angle is easy. Make the confidential information be peeped by others and cause the leakage of the confidential information. Therefore, in order to meet the two different needs of providing multiple viewers and processing confidential information in public places, adjustable viewing angle displays with switchable wide viewing angle display mode and narrow viewing angle display mode have gradually become one of the mainstream products in the display market. [0003] The anti-peeping mechanism of the existing display can be roughly divided into the following several technologies: [0004] 1. Install ant...
