Embodiment 1

[0033] see figure 1 and figure 2 , this embodiment provides an integrated shading panel 10, including a transparent box body 11, a first conductive layer 12 and a shading powder layer 13, wherein an inner cavity is formed inside the transparent box body 11; the first conductive layer 12 covers On the inner wall of the transparent box body 11; the light-shielding powder layer 13 is filled in the inner cavity of the transparent box body 11, where the light-shielding powder layer 13 includes charged light-shielding particles, and the charged light-shielding particles are adsorbed on the first conductive layer 12 in the electrified state superior. It can be understood that the integrated shading panel 10 is used on a display device or a touch display device, the transparent box body 11 can cover the visible area and the non-visible area of ​​the display module or the touch module, and the first conductive layer 12 can be It is a display electrode layer or a touch electrode laye...

Embodiment 2

[0040] see image 3 , the integrated shading panel provided in this embodiment is basically the same as that of Embodiment 1, the difference is that: the integrated shading panel 10 also includes a second conductive layer 14, and the second conductive layer 14 is covered on the far side of the transparent box body 11. On the inner wall of the first conductive layer 12, and the on-off state of the second conductive layer 14 is different from the on-off state of the first conductive layer 12, that is, the second conductive layer 14 is on the display device or touch display device. Power on when the screen is off, and power off when the visible area of ​​the display module is lit and / or the touch module is triggered; the charged shading particles in the shading powder layer 13 are adsorbed on the second conductive layer 14 in the energized state. Specifically, the second conductive layer 14 is a transparent conductive film. When the display device or the touch display device is o...

Embodiment 3

[0042] see Figure 4 , the integrated shading panel provided by this embodiment is basically the same as that of Embodiment 2, the difference is that: the second conductive layer 14 is a grid electrode 14', and the electrode wire of the grid electrode 14' can be adjusted according to specific conditions and requirements Different diameters are used and different arrangements are used to make the grid electrodes 14' present different patterns as a whole, so that when the display device or the touch display device is off the screen, the integrated light-shielding panel 10 can display different patterns, which plays a more important role. Good decorative effect.

Abstract

The invention provides an integrated shading panel which comprises a transparent box body, a first conductive layer and a shading powder layer; an inner cavity is formed in the transparent box body; the first conductive layer covers the inner wall of the transparent box body; the inner cavity is filled with the shading powder layer, the shading powder layer comprises charged shading particles, andthe charged shading particles are adsorbed to the first conductive layer in the power-on state. The first conductive layer is in a power-off state, the shading powder layer can form an integrated shading layer in the transparent box body to completely shade a visible area and a non-visible area of a display module; the first conductive layer is in a power-on state, charged shading particles in the shading powder layer are adsorbed on the first conductive layer, so that the visible area of the display module can be exposed, the technical problem that an integrated black panel cannot completelyeliminate the color difference between the visible area and the non-visible area of the display screen is effectively solved, and the integrated effect of the touch display device is improved.

Description

technical field [0001] The invention belongs to the technical field of touch display devices, and more specifically relates to an integrated light-shielding panel and a touch display device. Background technique [0002] At present, most of the integrated black panels on the market achieve the effect of integrated black through the following two methods: 1. Plating a layer of non-visible area close to the display screen on the area of ​​the glass substrate corresponding to the visible area of ​​the display screen The color film layer, 2. Cover a layer of light-shielding film on the entire surface of the glass substrate to reduce the color difference between the visible area and the non-visible area, so that the optical sensory effects of the two areas are as close as possible in the state of the screen. However, both methods cannot completely eliminate the color difference between the two regions, and reduce the transmittance of light emitted by the display screen, which aff...
