Embodiment 1

[0053] In this embodiment, the above-mentioned display substrate is the color filter substrate 01 as an example for description.

[0054] In this case, if figure 2 As shown, the display substrate includes a black matrix 11 on the base substrate 10 , and the pressure sensing structure 20 is located between the black matrix 11 and the base substrate 10 . Wherein, the above-mentioned color filter substrate 01 further includes a black matrix 11 and a color filter layer 12 . The color film layer 12 is composed of a first color pattern, a second color pattern and a third color pattern. The above-mentioned first color, second color and third color may be respectively red, green and blue which constitute the three primary colors, or may also be cyan, magenta and yellow. The present invention is not limited thereto. However, in the following embodiments, the first color is red (R), the second color is green (G), and the third color is blue (B).

[0055] In addition, when the above...

Embodiment 2

[0060] In this embodiment, the above-mentioned display substrate is the color filter substrate 01 , and the pressure sensing structure 20 is disposed in the non-display area 102 .

[0061] Specifically, such as Figure 4 As shown, at least one material constituting the first color pattern (R), the second color pattern (G) and the third color pattern (B) is included between the common electrode layer 13 and the second pressure-sensitive electrode 202 . In addition, the insulating pillars 203 and the black matrix 11 can have the same layer and the same material.

[0062] In this way, during the preparation process of the above-mentioned color filter substrate 01 , the preparation of the sensing electrode structure 20 can be completed. Specifically, firstly, the first pressure-sensitive electrode 201 is formed by a patterning process at the position corresponding to the non-display area 102 on the surface of the base substrate 10, and then a thin film is coated on the base subst...

Embodiment 3

[0066] In this embodiment, the above-mentioned display substrate is the color filter substrate 01 , and the pressure sensing structure 20 is disposed in the non-display area 102 . The difference from the second embodiment is that the insulating pillars 203 are made of different materials, and the common electrode layer 13 and the second pressure-sensitive electrode 202 can be reused.

[0067] Specifically, such as Figure 5 As shown, the second pressure-sensitive electrode 202 and the common electrode layer 13 have the same layer and the same material. The insulating support 203 is formed by sequentially stacking at least one of the materials constituting the black matrix 11 , the first color pattern (R), the second color pattern (G) and the third color pattern (B).

[0068] In this way, during the preparation process of the above-mentioned color filter substrate 01 , the preparation of the sensing electrode structure 20 can also be completed. Specifically, first, the first ...

Abstract

The invention relates to a display base plate, a display device, a pressure detection system and a detection method thereof and relates to the field of display technology. Environment pressure test functions can be integrated in the display base plate, thereby improving convenience to carry objects when people go out. The display base plate comprises a substrate base plate and a pressure sensing structure which is arranged on the substrate base plate and used for testing environment pressure. The pressure sensing structure comprises oppositely arranged first and second pressure-sensitive electrodes, and multiple separately-arranged insulation support columns arranged between the first pressure-sensitive electrode and the second pressure-sensitive electrode. The first pressure-sensitive electrode contacts with the substrate base plate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a display device, a pressure detection system and a detection method thereof. Background technique [0002] With the continuous improvement of living standards, people pay more and more attention to their own health, as well as life or environmental factors that may affect health. For example, high-altitude passengers, pilots, and outdoor mountaineering and exploration users; or, for those working in submarines and diving users, it is necessary to know the surrounding air pressure or water pressure to judge whether it is in line with their own physical adaptability . However, in the prior art, an independent device is generally used to test air pressure or water pressure. Therefore, the quantity of articles carried when people go out is increased, and the convenience of carrying articles is reduced. Contents of the invention [0003] Embodiments of the ...
