Embodiment 2

[0096] see Figure 5 , the embodiment of the present invention provides a method for displaying a picture, the execution subject of the method may be the liquid crystal display panel provided in Embodiment 1, and the method includes:

[0097] Step 201: Obtain the gray scale value of the currently displayed image.

[0098] The current display picture may include multiple grayscale values. In the embodiment of the present invention, when the grayscale detection unit obtains the grayscale value of the current display picture, in order to meet the display requirements of the current display picture, the grayscale detection unit can select from the current Select the maximum gray scale value in the display screen. Certainly, in order to improve efficiency, the grayscale detection unit may also randomly select a grayscale value from the currently displayed picture. In order to reduce the power consumption of the liquid crystal display panel to a greater extent, the grayscale detec...

Abstract

The invention discloses a liquid crystal display panel and a method for displaying a picture, and belongs to the technical field of terminals. The liquid crystal display panel comprises a driving voltage obtaining module and a liquid crystal display panel module. The driving voltage obtaining module is electrically connected with the liquid crystal display panel module. The driving voltage obtaining module is used for obtaining the gray-scale value of the currently-displayed picture, determining the value of driving voltage according to the gray-scale value and transmitting the value of the driving voltage to the liquid crystal display panel module. The liquid crystal display panel module is used for generating a control signal according to the value of the driving voltage and displaying the currently-displayed picture according to the control signal, wherein the control signal carries the value of the driving voltage. The power consumption of the liquid crystal display panel can be reduced.
