Color film substrate, display module and electronic device

Abstract

The invention relates to a color film substrate, a display panel and an electronic device. The color film substrate comprises a color resistance layer, a quantum dot material layer arranged on one side of the color resistance layer and used for emitting infrared rays when ultraviolet rays are received, and a sensor arranged on one side of the color resistance layer and used for generating an electric signal according to infrared rays reflected by a fingerprint to perform fingerprint identification. According to the color film substrate, the display panel and the electronic device provided by embodiments of the invention, a black matrix is relatively close to a finger of a user, and relative to a mode of directly emitting the infrared rays through a backlight module to irradiate the fingerprint of the user, the infrared rays can pass through relatively few film layers before the infrared rays are irradiated to the fingerprint, so that the intensity of the infrared rays irradiated on the fingerprint can be effectively ensured, the infrared rays reflected to the sensor also have relatively intensity, and the fingerprint identification precision is improved.

Description

technical field [0001] The present disclosure relates to the technical field of terminals, and in particular to a color filter substrate, a display module and an electronic device. Background technique [0002] At present, the fingerprint recognition structure in mobile phones is generally to install a fingerprint recognition sensor on the physical button to achieve the purpose of compatible button and fingerprint recognition. [0003] Since the sensor and the physical button need to be installed at the position of the physical button, and because the sensor also has a certain thickness, compared with only setting the physical button, the space under the upper cover of the mobile phone will be larger, which will easily lead to the instability of the overall structure of the mobile phone . [0004] And in order to enable the sensor to recognize fingerprints well, it is necessary to set a relatively large area to set the sensor, that is, the physical buttons need to be set la...

[0003] Since the sensor and the physical button need to be installed at the position of the physical button, and because the sensor also has a certain thickness, compared with only setting the physical button, the space under the upper cover of the mobile phone will be larger, which will easily lead to the instability of the overall structure of the mobile phone

[0004] And in order to enable the sensor to recognize fingerprints well, it is necessary to set a relatively large area to set the sensor, that is, the physical buttons need to be set larger, which requires the mobile phone screen to be set smaller, which affects the user's viewing Effect
