Problems solved by technology

[0005] However, the inventor found that when the external ambient light is relatively weak, the change between the detection results of the light sensor on the amount of light before and during the touch is not obvious. Even if the user performs a touch operation, the detection device cannot detect

Abstract

The present invention describes a display panel and a display device. The display panel includes a first substrate and a second substrate oppositely arranged, and at least one detector arranged between the first substrate and the second substrate; the detector includes a photosensitive part and a The housing part; the photosensitive part is located on the side of the first substrate facing the second substrate; the housing part is located between the photosensitive part and the second substrate, and the housing part includes a housing space and an opening, and the opening is arranged towards the photosensitive part; when the first substrate and the second substrate When the distance between the substrates changes, the storage part changes the degree of storage of the photosensitive part, so that the light received by the photosensitive part changes; the photosensitive part changes the resistance value by sensing the light change it receives, and outputs different sensing signals. The accommodating part amplifies the change of the light at the position of the photosensitive part, and improves the detection sensitivity of the detector.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the increasing number of multimedia devices, people are talking more and more about touch screens, because as a new input device, touch screens have many advantages such as ruggedness, fast response, space saving, and easy communication. With this technology, the user can operate the host by lightly touching the display screen with a finger, thus making the human-computer interaction more straightforward. This technology greatly facilitates those users who do not understand computer operations. [0003] To distinguish touch screens from the technical principles, they can be divided into the following basic types: pressure-sensitive touch screens, resistive touch screens, capacitive touch screens, surface acoustic wave technology touch screens, and light-sensitive touch screens. [0004] Light-based...
