Problems solved by technology
However, for non-self-luminous display screens such as LCD screens, under-screen biometric detection needs to solve the problem of the screen's transmittance of the detection beam
In order to solve this problem, the existing method is to develop an infrared penetrating backlight film, and install the biometric detection module under the backlight module to realize the biometric detection under the screen. However, this solution requires an external infrared light source. The external infrared light source occupies the space of the display screen, and can only realize biometric detection in a fixed area, which increases the cost of the product and reduces the competitive advantage of off-screen biometric detection technology

Abstract
The invention discloses an electronic terminal and a display module. The display module comprises the following components of: a sensing assembly; a backlight assembly, wherein the backlight assemblyis located above the sensing assembly and comprises a semi-reflecting and semi-transmitting membrane, a light guide plate, a light conversion layer and a backlight source, wherein semi-reflecting andsemi-transmitting membrane, the light guide plate and the light conversion layer are sequentially arranged in a stacked mode, and the backlight source is arranged on one side of the light guide plate,and is used for emitting light with a preset wavelength, wherein the light with the preset wavelength is used for exciting the light conversion layer, so that the quantum dot material in the light conversion layer emits visible light and infrared light; and a liquid crystal box arranged on the backlight assembly. According to the electronic terminal and the display module provided by the invention, an infrared light source will not occupy the space of the display module.
Description
technical field [0001] The invention relates to the field of display technology, in particular to an electronic terminal and a display module. Background technique [0002] With the continuous development of display technology, consumers' requirements for electronic terminal products continue to increase, and various electronic devices emerge in endlessly and develop rapidly. [0003] At present, electronic devices are developing towards the trend of thin, light and full screen. Recently, in order to achieve a full screen or near-full screen effect, the off-screen biometric detection technology has emerged as the times require. The off-screen biometric detection technology is to set the biometric detection module under the display screen to send or receive detection beams through the display screen. Implement biometric detection. However, for non-self-illuminating display screens such as liquid crystal display screens, under-screen biometric detection needs to solve the pr...
