Problems solved by technology

[0003] In order to improve the screen-to-body ratio, there are serious defects in the imaging of the fingerprint sensor in the current LCD display solution. Either the image quality of the small hole imaging solution is not good, or the optimization of the small hole imaging solution will affect the normal display function.

Embodiment 1

[0038] see figure 1 As shown, a display panel control system 100 is provided in the first embodiment, including a display unit 10 , a sensing unit 20 , a control unit 30 and a sensor unit 40 . Specifically, the display unit 10 is used to display images; the sensing unit 20 is electrically connected to the display unit 10 for sensing the touched area of ​​the display unit 10, and the sensing unit 20 includes a touch layer ; The control unit 30 is electrically connected to the display unit 10 and the sensing unit 20; as figure 2 As shown, when the display unit 10 is touched, it is used to control the formation of a plurality of light-transmitting holes 4 in the touch area for transmitting fingerprint signals; when the display unit 10 is not touched, it is used to control the The display unit 10 performs screen display; the sensor unit 40 is electrically connected to the control unit 30 and is set corresponding to the display unit 10, and is used to receive the fingerprint sign...

Embodiment 2

[0049] see Figure 5 As shown, in the second embodiment, all technical features in the first embodiment are included, and the difference is that the material of the liquid crystal layer 3 in the second embodiment includes thermotropic liquid crystal or lyotropic liquid crystal (ie common liquid crystal) , the liquid crystal molecules include biphenyl liquid crystals, phenylcyclohexane liquid crystals or ester liquid crystals; the first substrate 1 includes an array substrate 11 and a lower polarizer 12, and the lower polarizer 12 is arranged on the array substrate 11B away from One side of the liquid crystal layer 3 ; the second substrate 2 includes a color filter substrate 21B and an upper polarizer 23 , and the upper polarizer 23 is arranged on a side of the color filter substrate 21B away from the liquid crystal layer 3 . Wherein, the combination of the liquid crystal molecules and the upper polarizer 23 and the lower polarizer 12 is to achieve the purpose of controlling li...

Abstract

The invention provides a display panel control system and a display panel control method. The display panel control system includes a display unit, a sensing unit, a control unit and a sensor unit. When the display unit is touched, it is used to control the formation of multiple light transmission holes in the touch area; when the display unit is not touched, it is used to control the display unit to display a picture; the sensor unit is used for The fingerprint signal passing through the light hole is received, and the fingerprint image is collected. The control method of the display panel includes steps: a display step, a sensing step, a control step and a fingerprint image collection step. Under the premise of not affecting the normal display function, the present invention realizes 100% full-screen fingerprint identification and improves the screen-to-body ratio.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel control system and a display panel control method. Background technique [0002] With the improvement of the overall process design capability of mobile phones, consumers' aesthetics are constantly being guided and improved. The overall trend of mobile phone screens has gradually shifted from the previous diversified design to the direction of full-screen design. Therefore, in less than a year, the design capabilities and process capabilities of full-screen related indicators in displays such as chip-on-flex (COF), ultra-narrow bezel, and notch (Notch) have been continuously improved. The ratio has gradually increased from 80% to 97%. Among them, the research on in-screen fingerprint recognition is particularly popular. It directly integrates the fingerprint module into the screen, which greatly increases the screen-to-body ratio. [0003] In order to improve the screen-to-b...
