Embodiment Construction

[0037] Please refer to figure 2 , figure 2 It is an embodiment of the liquid crystal display panel and its driver of the present invention. The LCD panel 100 includes a display area 112 and a non-display area 114 . The display area 112 includes a thin film transistor array, and the non-display area 114 includes a gate driver 120 , a master source driver 140 and a slave source driver 160 for driving transistors in the thin film transistor array.

[0038] The display control circuit 182 on the circuit board 180 only transmits a digital image signal to the main source driver 140 through a flexible board 150 . The main source driver 140 generates a slave source driver signal and a gate driver signal according to the digital image signal and transmits them to the slave source driver 160 and the gate driver 120 respectively. The digital image signal, the gate driving signal and the slave source driving signal are all TTL or CMOS logic levels. Since the price of the flexible bo...

Abstract

The invention discloses a driver on a liquid crystal display panel and a related control method, which can effectively make a signal transferred through a line on the liquid crystal display panel have low-voltage swing amplitude and an adjustable low rotating speed. The liquid crystal display panel is connected to a display control circuit through a soft plate and comprises a master source driver, a gate driver and a slave source driver, wherein the master source driver receives a digital image signal of a first electrical specification output by the display control circuit through the soft plate and converts the digital image signal into a gate driving signal and a slave source driving signal of a second electrical specification; the gate driver can receive the gate driving signal of the second electrical specification; the slave driver can receive the slave source driving signal of the second electrical specification; and the master source driver, the slave source driver and the gate driver drive a thin film transistor array of the liquid crystal display panel.

Description

technical field [0001] The present invention relates to a driver on a liquid crystal display panel and a related method, in particular to a transmission signal of low swing voltage and slow high-low transition between drivers on a liquid crystal display panel . Background technique [0002] Please refer to figure 1 , figure 1 It is a schematic diagram of an existing liquid crystal display panel and its driver. Generally speaking, the LCD panel 10 can be divided into a display area 12 and a non-display area 14 . The display area 12 includes a thin film transistor array (TFT array), and the non-display area 14 includes a gate driver (gated driver) 20, a main source driver (master source driver) 40 and a slave source driver (slave source driver) 60 is used to control the transistors in the TFT array. [0003] Taking a liquid crystal display panel with a resolution of 800*480 as an example, the gate driver 20 needs 480 connections to connect to the thin film transistor arra...
