Problems solved by technology

When the laser pointer is projected onto the display surface of the display panel, part of the incident light is absorbed. On the other hand, due to the high brightness of the display panel itself, the viewers and users will not be able to clearly see the bright spots projected by the laser pointer on the display panel. You can't even see the bright spots, which seriously affects the presentation effect

Abstract

The invention relates to a display panel capable of recognizing external light. The display panel comprises a color filter substrate, a thin film transistor array substrate and a liquid crystal layer,the color filter substrate and the thin film transistor array substrate are oppositely arranged, the liquid crystal layer is filled between the color filter substrate and the thin film transistor array substrate, the thin film transistor array substrate comprises a display area and a non-display area, and a plurality of optical sensors are arranged in the display area; a plurality of light holesare arranged in the color filter substrate; and a plurality of sub-pixels are arranged on the thin film transistor array substrate, and each optical sensor is used for detecting position information corresponding to an external photoelectric signal when the external photoelectric signal is received. According to the display panel, the plurality of optical sensors are arranged on the thin film transistor array substrate, when an incident laser irradiates the optical sensors, the optical sensors can be triggered to work, and a laser projection position is determined so that a gray scale of sub-pixels in a laser irradiation area is changed, and a demonstration effect is improved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel capable of identifying external light. Background technique [0002] Laser pointer, also known as laser pointer, is a pen-shaped transmitter designed with visible laser light as portable, easy to hold, and processed by laser modules (light-emitting diodes). It has been widely used in electronic teaching, presentations and reports. Speech etc. [0003] In some application scenarios, liquid crystal display panels such as LED (Light Emitting Diode) and OLED (Organic Light Emitting Diode) need to be used in conjunction with a laser pointer to achieve better presentation effects. When the laser pointer is projected onto the display surface of the display panel, part of the incident light is absorbed. On the other hand, due to the high brightness of the display panel itself, the viewers and users will not be able to clearly see the bright spots projected b...
