Embodiment Construction

[0091] Please refer to FIG. 3 , which is a schematic block diagram of a driving circuit of a liquid crystal display in a first preferred embodiment of the present invention. As shown in Figure 3, the drive circuit 300 includes a first timing controller 330, a second timing controller 340, and a plurality of data driving controllers 351, 352, 353, 354 (in this case, four data driving controllers example, but not limited to four data-driven controllers).

[0092] The image data transmission method of the known technology is to divide the digital image data into an odd part (Odd Part) 310 and an even part (Even Part) 320, and the odd part (Odd Part) 310 and the even part (Even Part) 320 can use half of the bus respectively . Wherein, the odd part (Odd Part) 310 of the digital image data includes odd sets of image data 310A, 310B, 310C, and 310D, and each set of image data includes image data transmitted by more than one data line (Data Line). . In addition, the even part (Even...

Abstract

The invention provides a drive circuit and a drive method of a liquid crystal display, which achieves the aim of driving a liquid crystal panel without using a pre-processor. The drive circuit comprises a first time schedule controller which is a first part used for receiving a piece of digital image data, a second time schedule controller which is a second part used for receiving a piece of digital image data, and a plurality of data drive controllers, each of which is electrically connected with the first time schedule controller and the second time schedule controller. Complete image data can be displayed on a liquid crystal panel by using the first time schedule controller and the second time schedule controller to control a plurality of data drive controllers.

Description

technical field [0001] The present invention relates to a driving circuit and a method of a liquid crystal display, in particular to a driving circuit and a method of a liquid crystal display without using a pre-processor (Pre-processor). Background technique [0002] Liquid Crystal Display (LCD) utilizes the action of an external electric field to make the liquid crystal molecules change from a specific initial molecular arrangement to other molecular arrangement states, so that the optical properties are changed and converted into visual changes. From the perspective of the physical characteristics of liquid crystal molecules, the liquid crystal molecules must be turned by an external electric field (voltage), and the light transmittance of each pixel on the liquid crystal panel can be changed by the turning of the liquid crystal molecules to achieve the purpose of imaging. However, because the response time of the liquid crystal molecules is relatively slow, when the data...
