Problems solved by technology

The infrared detector module in the fingerprint recognition under the external screen will occupy too much space on the mobile phone screen, which is not conducive to the narrow frame and reduces the screen ratio. The separately set infrared light source increases the power consumption of the system and requires a separate process to set the infrared detector module also increases the production cost

Abstract

The invention discloses a display device. The display device comprises a backlight module and a display panel positioned on the light emitting side of the backlight module, wherein the display area ofthe display panel comprises a first display area and a fingerprint identification area; the backlight module comprises a quantum dot film which comprises a first quantum dot film area corresponding to the fingerprint identification area and a second quantum dot film area corresponding to the first display area; first quantum dots, second quantum dots and third quantum dots are arranged on the first quantum dot film area; the first quantum dots emit first color light after being excited by the backlight source, the second quantum dots emit second color light after being excited by the backlight source, and the third quantum dots emit infrared light after being excited by the backlight source. The quantum dot film is arranged in the backlight module and corresponds to the display area, spaces do not need to be separately arranged for the quantum dot film, narrow frames of the display device are favorably realized, the screen occupation ratio is improved, and the structure is more exquisite.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display device. Background technique [0002] With the development of science and technology, human beings' dependence on electronic devices is increasing day by day, so the requirements for electronic devices are also getting higher and higher. Nowadays, users generally require advantages such as light weight and thin thickness for electronic devices. Low Temperature Poly-silicon Liquid Crystal Display (LTPS LCD) has the advantages of light weight, thin thickness, low power consumption and low radiation, and has been widely used in information technology, multimedia technology and other fields. A liquid crystal display generally includes a backlight module array substrate, a liquid crystal layer, a color filter substrate, and the like. In addition to the advantages of light weight and thin thickness, users have higher and higher requirements for the display...
