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, and on the other hand, the brightness of the display panel itself is relatively high, which will cause viewers and users to not 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 and a display method. The display panel includes a color filter substrate and a thin film transistor array substrate arranged oppositely, and a liquid crystal layer is filled between the color filter substrate and the thin film transistor array substrate. , wherein the thin film transistor array substrate includes a display area and a non-display area, a plurality of light sensors are arranged in the display area, and a plurality of control switches are arranged in the non-display area; A light-transmitting hole is opened at a position vertically corresponding to the light sensor, and a plurality of sub-pixels are arranged on the thin film transistor array substrate. The display panel is provided with a plurality of light sensors and a plurality of control switches on the thin film transistor array substrate. When the incident laser light is irradiated on the light sensor, the light sensor and the control switch can be triggered to work, and the laser projection position can be determined to change the sub-pixels in the laser irradiation area. to enhance the presentation effect.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel and a display method. 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) also 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, and on the other hand, the brightness of the display panel itself is relatively high, which makes it difficult for viewers and users to see the bright spots projected by the...
