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 invention discloses a display panel and a display device. The display panel comprises a first substrate and a second substrate which are oppositely arranged, and at least one detector which is arranged between the first substrate and the second substrate. The detector comprises a light sensing part and a containing part. The light sensing part is located on the side, facing the second substrate, of the first substrate. The containing part is located between the light sensing part and the second substrate. The containing part comprises a containing space and an opening. The opening faces the light sensing part. When the distance between the first substrate and the second substrate changes, the containing part changes the containing degree for the light sensing part, and light rays received by the light sensing part is changed; the light sensing part changes the resistance value and outputs different sensing signals by sensing the changes of the light rays received by the light sensing part. The containing part amplifies the changes of the light rays at the position where the light sensing part is located, and the detection sensitivity of the detector is improved.

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...
