Embodiment 1

[0044] Such as figure 1 As shown, a display assembly 1 provided by the present application includes a glass substrate 101, a first TFT liquid crystal assembly 102, a spacer plate 103 and a second TFT liquid crystal assembly 104 arranged in sequence. Among them, the first TFT liquid crystal component 102 includes a first liquid crystal layer 1021 and a first TFT substrate 1022 for driving the first liquid crystal layer 1021, and the second TFT liquid crystal component 104 includes a second liquid crystal layer 1041 and a first TFT substrate 1022 for driving the second liquid crystal layer. 1041 of the second TFT substrate 1042 .

[0045] Wherein, the spacer 103 is used to separate the first TFT liquid crystal assembly 102 and the second TFT liquid crystal assembly 104, so that the first TFT liquid crystal assembly 102 and the second TFT liquid crystal assembly 104 all have independent electric fields after receiving the voltage signal, so as to The first liquid crystal layer 1...

Embodiment 2

[0060] based on figure 1 As shown in the display assembly 1, the present application also provides a display panel, such as diagram 2-1 As shown, the display panel includes a display component 1, a controller 2 and multiple source drivers (Source Driver, DR).

[0061] Wherein, the controller 2 may be a timing controller (Timer Control Register, TCON). The main function of TCON is to convert the received image data signal into a timing control signal, and provide the timing control signal to the source driver, which is used by the source driver to convert the timing control signal into a voltage signal of corresponding amplitude and send it to the corresponding TFT substrate to apply voltage to the corresponding liquid crystal layer.

[0062] Such as diagram 2-1 As shown, the plurality of source drivers includes a first source driver and a second source driver. The first source driver is connected to the first TFT substrate 1022 , and the second source driver is connected...

Embodiment 3

[0077] Based on the above display panel, the present application also provides a driving method, such as Figure 3-1 As shown, it is a flow chart of an embodiment of a driving method provided by the present application. The main body of the driving method is the display panel, which can be specifically executed by the controller in the display panel. The method includes:

[0078] S201: Acquire a target grayscale signal;

[0079] Wherein, the target grayscale signal is a grayscale signal corresponding to the target image data to be displayed.

[0080] S202: Find the target light transmittance corresponding to the target gray scale signal according to the preset gamma curve corresponding to the gray scale-light transmittance.

[0081] S203: Determine a first grayscale voltage and a second grayscale voltage corresponding to the target light transmittance according to a preset mapping table.

[0082] In an example, the mapping table may include a first grayscale voltage, a secon...

Abstract

The invention provides a display assembly, a display panel and a driving method, and mainly relates to the field of displays. The display assembly comprises a first glass substrate, a first TFT liquid crystal assembly, a spacing board and a second TFT liquid crystal assembly which are arranged in sequence. Wherein the first TFT liquid crystal assembly comprises a first liquid crystal layer and a first TFT substrate used for driving the first liquid crystal layer, and the second TFT liquid crystal assembly comprises a second liquid crystal layer and a second TFT substrate used for driving the second liquid crystal layer. The polarization direction of light is accurately controlled through the two liquid crystal layers, and the problem that the contrast ratio and the color precision of a liquid crystal display panel are low can be solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display component, a display panel and a driving method. Background technique [0002] In the context of the gradual maturity and improvement of liquid crystal display (Liquid Crystal Display, LCD) related processes and technologies, people have higher and higher display requirements for LCD display panels, pursuing higher contrast and higher color display effects LCD. Therefore, how to improve the display effect of the display panel of the LCD is a hot issue in the LCD field at present. Contents of the invention [0003] The present application aims to provide a display component, a display panel and a driving method, which can solve the problem of low contrast and color richness of the LCD display panel. [0004] In a first aspect, the present application provides a display assembly, which includes a first glass substrate, a first TFT liquid crystal assembly, a s...
