Problems solved by technology

However, due to the large number of pulses corresponding to the power supply signal, this causes the second drive circuit to spend a long time in the identification process
Moreover, the second drive circuit usually needs to output a plurality of power supply signals. At this time, the number of pulses needs to be grouped and identified, which undoubtedly further increases the identification time, resulting in low identification efficiency.

Abstract

Embodiments of the present invention provide a control method of a power driver, a power driver, and a display device, which relate to the field of display technology and are used to shorten the recognition time of power signals and improve recognition efficiency. The above control method includes: the control circuit of the power driver outputs a clock control signal, and outputs a binary level signal according to the power supply voltage control signal; the power signal output circuit of the power driver outputs an actual power supply voltage signal according to the clock control signal and the binary level signal. The above control method is used to control the output of the actual power supply voltage signal.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, and in particular, to a control method of a power driver, a power driver and a display device. 【Background technique】 [0002] A display device generally includes a first driving circuit, a second driving circuit and a display panel, where the first driving circuit is used to control the second driving circuit to output a power signal to drive the display panel to work normally. [0003] Based on the current control method, the first driving circuit outputs a specific pulse signal to the second driving circuit, and the second driving circuit determines the voltage value of the power supply signal to be output by identifying the number of pulses contained in the pulse signal. However, due to the large number of pulses corresponding to the power supply signal, it takes a long time for the second driving circuit to identify. In addition, the second driving circuit usually needs to output...
