Crystal display device and related drive method thereof

Abstract

The invention discloses a liquid crystal display device including a double source electrode drive circuit and an associated driving method, the device uses a data write-in synchronous control mechanism to execute write-in operations of image data signal. The operations of the data write-in synchronous control mechanism comprises the steps of: utilizing a first and a second source electrode drive circuit to respectively lock odd and even image data signals; utilizing the first source electrode drive circuit to process the odd image data signal in order to generate a first group of analog data signals; utilizing the second source electrode drive circuit to process the even image data signal in order to generate a second group of analog data signals; writing the first group of analog data signals in a plurality of first pixel units; and writing the second group of analog data signals in a plurality of second pixel units. The invention can save side frame areas and power consumption caused by using a data processing interface circuit to perform data analysis and down frequency processing.

Description

Technical field [0001] The invention relates to a liquid crystal display device and a related driving method, in particular to a liquid crystal display device and a related driving method based on a dual-source driving circuit with a data writing synchronization control mechanism. Background technique [0002] Liquid Crystal Display (LCD) is a type of flat panel display widely used at present, which has the characteristics of light and thin appearance, power saving, and no radiation pollution. The working principle of the liquid crystal display device is to change the voltage difference between the two ends of the liquid crystal layer to change the arrangement of the liquid crystal molecules in the liquid crystal layer to change the light transmittance of the liquid crystal layer, and then cooperate with the light source provided by the backlight module to display images. [0003] Generally speaking, a liquid crystal display device uses a plurality of data lines and a plurality o...

Problems solved by technology

However, when the resolution of the liquid crystal display panel is higher, or the number of gray scales of the image data signal is larger, the data processing interface circuit needs to design more stages to quickly perform data extraction and frequency reduction processing of the image data signal, so The liquid crystal display device will consume a considerable frame area to set up the data processing interface circuit. In addition, the power consumption will be significantly increased during the operation of the liquid crystal display device.
