Problems solved by technology

[0004] However, when the flat display panel is flexible, when the display is curved, no matter the shape of the panel is concave or convex, the brightness of some display areas in the display panel is particularly bright. The brightness of some display areas is particularly dark
That is to say, for a bendable flat display panel, when the panel is bent and displayed, different uniformity of brightness will occur, which will cause the problem of poor display effect
Therefore, if only the microstructure of the light guide plate mentioned in the previous input technology is used, it is impossible to maintain the uniform brightness of each display unit during the bending display process of the flexible flat display panel.
[0005] Therefore, how to solve the problem of uneven brightness of the flexible display panel in the prior art is an urgent issue to be solved.

Embodiment Construction

[0029] Please refer to FIG. 1 , which is a schematic diagram of a first embodiment of a display device with uniform brightness. The display device with uniform brightness proposed by the present invention includes: a bendable display module 10 , a sensing module 20 and a control module 30 .

[0030] The flexible display module 10 has a plurality of display units 12 (pixels). Each display unit 12 has its own transmittance, and light can determine the brightness of each area of ​​the flexible display module 10 according to the transmittance of the display unit 12 .

[0031] The sensing module 20 is disposed on the bending region 14 of the bendable display module 10. When the bendable display module 10 is bent, the bendable display module 10 will generate the bend region 14, as shown in FIG. 1 , when the bendable display module 10 When the left and right ends of the flexible display module 10 are normally bent, they are approximately at the centerline of the long sides of the fl...

Abstract

The invention discloses a display device of brightness uniformity and a method thereof. The device comprises a flexible display module, a sensing module and a control module. The flexible display module comprises a plurality of display units. The sensing module is arranged in the bent area of the flexible display module and generates curvature signals correspondingly according to the bent curvature of the flexible display module. The control module receives curvature signals and controls the penetration rate of each display unit according to the curvature signals.

Description

technical field [0001] The present invention relates to a display device and method, in particular to a display device and method with uniform brightness. Background technique [0002] Flat display panels (such as: liquid crystal display panels, etc.) have many advantages, such as: light and thin, power saving and other characteristics, so flat display panels gradually replace traditional display devices, and the application range is very wide, such as: notebook computers, TVs, personal Digital assistants (PDAs), mobile phones, digital photo frames, etc., can all see the application of flat display panels. Recently, in order to meet the different needs of more electronic products, more bendable display panels have been developed. [0003] Traditionally, the flat display panel has a backlight module for providing the light source required by the flat display panel. Wherein, the backlight module has a light guide plate (LGP), and the backlight module can provide a uniform li...
