Embodiment Construction

[0033] Embodiments of the present invention are described in detail below. The embodiments described below are exemplary only for explaining the present invention and should not be construed as limiting the present invention. If no specific technique or condition is indicated in the examples, it shall be carried out according to the technique or condition described in the literature in this field or according to the product specification.

[0034]In the related art, when the display device is in the off-screen state, the screen itself will be displayed in black, with a single color tone and poor visual effect, which cannot meet the needs of users. Therefore, the inventor intends to propose a touch display module that can display a predetermined color when the screen is off, so that the appearance of the display device is beautiful and meets the aesthetic needs of users. Therefore, the inventor has conducted a lot of research on the effect of the display device on the ambient ...

Abstract

The invention provides a touch display module, a display device and a method for controlling the touch display module to display a preset color in a screen-off state. The touch display module comprises a display module, a touch module and a circular polarizer touch module which are stacked in sequence, a preset included angle is formed between the direction of a first phase difference generated when ambient light irradiates the base material and the direction of a second phase difference generated when the ambient light irradiates the circular polarizer. The preset included angle enables the sum of the first phase difference and the second phase difference to be a preset phase difference, and in the screen-off state of the touch display module, after the ambient light is emitted into the touch display module, the preset phase difference enables only light with a preset color to be reflected out of the touch display module. The touch display module can display a preset color in a screen-off state, is attractive in appearance, meets aesthetic requirements of users, and is wide in application range and good in commercial prospect.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display module, a method for controlling the touch display module to display a predetermined color in a screen-off state, and a display device. Background technique [0002] In the related art, when the display device is in the off-screen state, the screen itself will be displayed in black, with a single color tone and poor visual effect, which cannot meet the needs of users. [0003] Therefore, the related technologies of the existing display devices still need to be improved. Contents of the invention [0004] The present invention is accomplished based on the following findings of the inventors: [0005] After a lot of in-depth investigations and experimental verifications on the influence of the structure in the touch display module on light, the inventors found that when ambient light shines into the touch display module, due to the ambient light and the ...
