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, comprising a color filter substrate, a thin film transistor array substrate arranged oppositely, and a liquid crystal layer filled between the color filter substrate and the thin film transistor array substrate, The thin film transistor array substrate includes a display area and a non-display area, and a plurality of light sensors are arranged in the display area; a plurality of light-transmitting holes are opened on the color filter substrate; A plurality of sub-pixels, the light sensor is used for detecting the position information corresponding to the external photoelectric signal when receiving the external photoelectric signal. The display panel is provided with a plurality of light sensors on the thin film transistor array substrate. When the incident laser light is irradiated on the light sensor, the light sensor can be triggered to work, and the laser projection position can be determined, thereby changing the gray scale of the sub-pixels in the laser irradiation area and improving the demonstration effect.

Description

technical field [0001] The invention belongs to the technical field of display, and in particular relates to a display panel capable of recognizing external light. Background technique [0002] A laser pointer, also known as a laser pointer, is a pen-shaped transmitter designed to be portable, easy to hold, and processed by a laser module (light-emitting diode) from a visible laser. It has been widely used in e-learning, presentations and reports. speeches 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 on the display surface of the display panel, a part of the incident light is absorbed. On the other hand, due to the high brightness of the display panel itself, the viewer and the user cannot see the bright spots projected by the laser pointer on t...
