Problems solved by technology

[0004] The main purpose of the present invention is to provide a display driving circuit, a display driving method, and a display device, so as to solve the problem in the prior art that the display driving method used in the display device includes a display panel in standby, which may cause a problem in the pixel circuit in the display panel. The data write transistor is prone to leakage, which will cause the display panel to flicker when the mode is switched, or increase the power consumption.

Embodiment approach

[0050] According to a specific implementation manner, the data voltage supply circuit may include a first voltage regulator;

[0051] The first voltage regulator is used to generate the off-data voltage according to the first power supply voltage, and provide the off-data voltage to the data line.

[0052] In the embodiment of the present invention, when the data writing transistor is a p-type transistor, the first power supply voltage may be the first high voltage AVDD, but not limited thereto.

[0053] Such as figure 2 shown in figure 1 On the basis of the shown embodiment of the display driving circuit, the data voltage supply circuit may include a first voltage regulator Rg1;

[0054] The first voltage regulator Rg1 is used for generating the shutdown data voltage Vs according to the first high voltage AVDD.

[0055] In the embodiment of the present invention, the voltage value range of Vs can be calculated first, and the first voltage regulator Rg1 generates the off-d...

Abstract

The invention provides a display driving circuit, a display driving method and a display device. The display drive circuit includes a control circuit and a data voltage supply circuit; the control circuit is used to provide an off control signal to the nth data driver when receiving an indication signal that the nth display panel is on standby, so as to control the nth data driver not to Work; the data voltage supply circuit provides an off data voltage to the data line included in the nth display panel when receiving the indication signal, so that the data writing transistor in the pixel circuit included in the nth display panel is turned off, and The gate-source voltage of the control data writing transistor is within a predetermined voltage range; n is a positive integer less than or equal to N. The invention can reduce power consumption, so that the data writing transistor is not easy to generate leakage, and it is not easy to cause the flicker problem when the display mode is switched.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display driving circuit, a display driving method and a display device. Background technique [0002] With the development of folding technology, there is more and more market for tablet and mobile phone integrated products, so this kind of product is undoubtedly power-hungry, so we need to try our best to save power consumption, especially in the mobile phone mode. There are many, but it also brings some problems. [0003] In the existing display driving circuit, when at least one display panel of the foldable display device is on standby, the power supply circuit is used to provide high or low voltage to the data lines in the display panel, which will cause the pixel circuits in the display panel to The data writing transistor in the display panel is prone to leakage, or it will cause the display panel to produce a flickering phenomenon when the mode is switched; or...
