Embodiment Construction

[0024] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0025]The invention provides a method for adjusting the picture of a liquid crystal display, and the method for adjusting the picture is mainly aimed at the situation that the liquid crystal display in a single-scan mode is installed upside down. There are many display errors in the picture display of the liquid crystal display screen in the single-scan mode at present. A single-scan display screen can only display a picture by scanning in a single direction, but when the single-scan display screen is installed upside down, the picture is displayed upside down. Nowadays, software programs are often used to solve the problem in technology. Although the single-scan display screen can display normally in general display when it is installed upside down, there are still p...

Abstract

The invention provides a method and system for regulating a picture of a liquid crystal display. The method for regulating the picture of the liquid crystal display comprises the first step of providing the liquid crystal display, wherein the liquid crystal display displays the picture in a single-direction scanning mode; the second step of further judging whether an original picture is displayed through the liquid crystal display or not when the liquid crystal display is installed in an inversion mode, wherein each pixel point of the original picture corresponds to a coordinate point in the liquid crystal display; the third step of modifying the coordinate point corresponding to each pixel point of the original picture to generate a regulated picture rotated by 180 degrees if the original picture is displayed through the liquid crystal display; the fourth step of displaying the final regulated picture through the liquid crystal display, wherein the final regulated picture is rotated by 180 degrees.

Description

technical field [0001] The invention relates to a method and a system for adjusting a picture of a liquid crystal display, in particular to a method and a system for adjusting a picture of a single-scan liquid crystal when it is installed upside down. Background technique [0002] At present, the scanning methods of LCD (Liquid Crystal Display) can be divided into single-scan and double-scan. Among them, single-scan only supports forward scan. When the single-scan display is inverted, the screen displayed on the display is also inverted. . Dual scan supports forward scan and reverse scan at the same time. When the dual-scan display screen is upside down, in the prior art, the display driver IC can be used to display the picture upside down, and by changing the scanning starting point and scanning direction of the display screen, the displayed picture can be rotated 180 degrees. That is to say, when the dual-scan display screen is inverted, the picture is also inverted, so ...
