Abstract

The invention relates to a voltage signal generating circuit, which comprises a control module and at least two delay modules, wherein the control module is used for generating control signals; and each delay module is connected with the control module separately for receiving reference voltage signals, delaying the reference voltage signals according to the control signals and outputted the reference voltage signals after delaying. In the above voltage signal generating circuit, the control module is adopted to generate the control signals, the delay module is also adopted to receive the reference voltage signals, the delay module delays the reference voltage signals according to the control signals and outputs the reference voltage signals after delaying, and thus, the delay module can independently adjust the delay time of the outputted voltage signals, and adjustment on the phase difference between the voltage signals outputted by each two delay modules can thus be realized.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a voltage signal generation circuit, method and display device. Background technique [0002] As people's demand for narrow bezel TVs becomes stronger and stronger, GDL (Gate driver less, no gate driver) liquid crystal display panels are becoming more and more popular. The GDL circuit is composed of level shifter IC (boost integrated circuit) and shift register (shift register). The level shifter IC is set on the driver board, the shift register is set on the liquid crystal display panel, and the level shifter IC transmits voltage signals to the shift register. Complete the driving of the liquid crystal display panel. The level shifter IC is disposed on the driving board so that the frame length of the liquid crystal display panel can be reduced. [0003] The voltage signal output by the level shifter IC has a certain phase difference. At present, the phase of the v...
