Problems solved by technology

[0003] It can be seen from the above that the above method mainly achieves the purpose of reducing power consumption by reducing the transmission of the same data, but in the above method, only when the data of two adjacent frames of images are exactly the same can the effect of reducing power consumption be achieved. So for dynamic displays, it has little effect

Embodiment Construction

[0039] The specific implementation manners of the image display method and the liquid crystal display provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] An image display method provided by an embodiment of the present invention, such as figure 1 As shown, the following steps may be included:

[0041] S101. Determine the polarity of each line of data corresponding to the nth frame of image to be displayed, and compare whether the polarity of each line of data corresponding to the n-1th frame of displayed image needs to be reversed.

[0042] If necessary, execute step S102, and if not, execute step S103.

[0043] S102. Control the polarity of each line of data corresponding to the frame image to be displayed to be reversed, and refresh the full screen according to the data of each line after polarity reversal, so as to display the frame image to be displayed.

[0044] S103. Comparing the ...

Abstract

The invention discloses an image display method and a liquid crystal display. Before a to-be-displayed frame of image is displayed, in a condition in which polarity for each row of data does not need to be reversed when the to-be-displayed frame of image is displayed, data corresponding to each row in the to-be-displayed frame of image is compared with data of a corresponding row in a former frame of image; and in the to-be-displayed frame of image, rows whose data are different from corresponding rows in the former frame of already-displayed image serve as change rows, and the change rows only need to be refreshed. Thus, as long as two frames of images with kept polarity have rows of the same data, when the latter frame of image in the adjacent two frames of images is displayed, the same row does not need to be refreshed, power consumption for image refreshing can be effectively reduced, and the image display power consumption can be effectively reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an image display method and a liquid crystal display. Background technique [0002] With the development of display technology, power consumption has always been a key indicator of display product design. Currently, in order to reduce power consumption, a panel self-refresh technology (PanelSelfRefresh, PSR) is introduced at a display interface (DisplayPort, DP) of a display device. That is, a remote frame buffer (RemoteFrameBuffer, RFB) is added to the clock controller of the display panel to store the data of the frame image to be displayed input by the external signal source, and before displaying the frame image to be displayed, the external signal source needs to first The data of the frame image to be displayed is compared with the data of the previous frame image. If the data is different, the external signal source will send the data of the frame image to be displayed t...
