Problems solved by technology

2 to 7, the first picture 42 and the second picture 44 are continuous two pictures (frames) (frame), and the polarity (polarity) of the display unit 46 in the first picture 42 is different from that displayed in the second picture 44. The polarity of the unit 46 is opposite. In addition, according to the different polarity arrangements between the display units 46, they are divided into single-row reverse drive, double-row reverse drive, and column reverse drive. The single-row reverse drive is different from the double-row reverse drive. As far as column reverse drive is concerned, it has better picture quality, but there will be flickering phenomenon when using single row reverse drive mode when repeating special image pictures

Embodiment Construction

[0026] Its hardware structure of the liquid crystal display applicable to the method of the present invention is similar to that of the liquid crystal display 10 in FIG. Please refer to FIG. 8 . FIG. 8 is a schematic diagram of differentiating display units of a liquid crystal display 50 according to the present invention. The liquid crystal display 50 includes a plurality of display units Ro, Go, Bo, Re, Ge, Be arranged in multiple rows, and each display unit is used to present corresponding gray scales of red, green and blue according to the display data. Wherein every three display units Ro, Go, Bo or Re, Ge, Be form a pixel (pixel). Although FIG. 8 only shows 20 pixels due to simplification, the liquid crystal display 50 actually includes many more pixels. According to the method of the present invention, each display unit Ro, Go, Bo, Re, Ge, Be of the liquid crystal display 50 will be divided into a plurality of groups 52, and each group 52 includes two pixels (that is, ...

Abstract

The present invention discloses method of controlling the operation of LCD. The LCD disease several display units arranged in several lines and alters the display characteristic of the display units every other picture period based on the received display data. The method is to switch the polarity operating mode of the LCD dynamically based on the display data of each of the display period in each picture period.

Description

technical field [0001] The invention relates to a method for controlling the operation of a liquid crystal display, in particular to a method for quickly eliminating the flickering of the picture of the liquid crystal display and maintaining the best picture quality. Background technique [0002] Liquid crystal displays have the characteristics of light and thin appearance, low power consumption, and no radiation pollution. They have been widely used in portable information products such as notebook computers and personal digital assistants (PDAs), and have even gradually replaced traditional desktops. Trends in Cathode Picture Tube (CRT) Monitors for Computers. Since liquid crystal molecules have different polarization or refraction effects on light in different alignment states, the amount of light transmission can be controlled through liquid crystal molecules in different alignment states, and output light of different intensities can be further generated. This property...
