Problems solved by technology

[0009] However, if figure 1 As shown, because the distance between the chip pin 103 and the signal transmission line 105 to be connected is different, the length of the transmission wiring 104 is different
The difference in the transmission wiring 104 will lead to different driving requirements corresponding to each driving signal, and if all the driving signals are designed based on the maximum driving requirements, it will cause waste of power consumption

Abstract

The invention discloses a drive chip used for driving a display panel, a display device and a drive control method. The drive chip has N pins which correspond to N signal transmission lines arranged on the display panel, the pins and the corresponding signal transmission lines are connected through transmission wires, the transmission wires include a first transmission wire connected with the first pin and a second transmission wire connected with the second pin, and the length of the first transmission wire is larger than that of the second transmission wire. The drive chip includes a signal generation module used for generating N drive signals, the N drive signals include a first drive signal corresponding to the first pin and a second drive signal corresponding to the second pin, and the current intensity of the first drive signal is larger than that of the second drive signal. According to the drive chip provided by the invention, the power dissipation of the drive chip is reduced.

Description

technical field [0001] The invention relates to the driving of a display panel, in particular to a driving chip for driving a display panel, a display device and a driving control method. Background technique [0002] In recent years, with the vigorous development of semiconductor technology, portable electronic products and flat panel display products are also emerging. Moreover, thin film transistor (TFT, Thin Film Transistor) liquid crystal display has gradually become a standard output device for various data products due to its advantages of low operating voltage, no radiation scattering, light weight, and small size. With various display devices, such as mobile phones, PAD and other systems becoming more and more integrated and thinner, the system CPU has gradually entered the market from the previous single-core, dual-core, quad-core and eight-core or even more core product systems. , The power consumption of the system is getting higher and higher, and the market ha...
