Abstract

The invention relates to the technical field of liquid crystal display, and particularly relates to a turn-on detection circuit, a resolution acquisition method and a display screen driving method and device. The resolution acquisition method comprises the steps that an LCD display screen is controlled to display a test frame according to initial resolution; and the turn-on state of the pixel points of the LCD display screen is detected through the turn-on detection circuit, and the resolution of the LCD display screen is acquired according to the turn-on state. The resolution parameters of the LCD display screen can be rapidly acquired after replacing of the LCD display screen so as to be rapidly adaptive to transformation of the screen size.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of liquid crystal display, and in particular, to a lighting detection circuit, a method for obtaining resolution, a method and a device for driving a display screen. Background technique [0002] With the rapid development of electronic technology, the use of LCD display in the field of electronic technology is becoming more and more common. Among them, LCD is the abbreviation of Liquid Crystal Display, and the LCD display is a liquid crystal display. LCD screens of different sizes often have different resolutions. [0003] In the process of realizing the present invention, the inventor has found that at least the following problems exist in the prior art: a controller in the prior art often needs to redevelop and reprogram the LCD driver when replacing LCD display screens of other sizes, so as to To adapt to its new resolution requirements, after the controller is replaced with L...
