[0036] As introduced in the background, the power consumption of the existing display screen is high when displaying pure color. To solve the problem that the existing pixel circuit structure and clock signal result in high power consumption of the display screen when displaying pure color, the embodiments of the present application provide a control method of pixel circuit, a display panel and a circuit driving device.

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described in connection with the drawings in the embodiments of the present application.

[0038] In the embodiment, a control method of a pixel circuit running on a mobile terminal or a computer terminal is provided. It should be noted that although a logical sequence is shown in the flowchart, in some cases, the steps shown or described can be performed in an order different from that shown here.

[0039] Figure 1 is a flowchart of a control method of a pixel circuit according to an embodiment of the present application. As shown in Figure 1 the pixel circuit includes a display array and a plurality of switch modules. The display array includes a plurality of display elements arranged in an array. The display elements displaying the same color in the same column are connected to the same switch module. The number of display elements displaying a preset color is a preset multiple of the number of display elements displaying each non-preset color. The plurality of switch modules includes a first switch module and a second switch module. The output end of the first switch module is electrically connected to the display elements displaying the preset color. The output end of the second switch module is electrically connected to the display elements displaying the non-preset color. The method includes the following steps:

[0040] Step S201, generating a driving signal and a plurality of clock signals. The driving signal is used to control the display elements to emit light or not to emit light. The clock signals correspond one-to-one to the switch modules.

[0041] Specifically, in general, the switch module is turned on when the clock signal is low, and the display element emits light when the driving signal is low. However, the functions of high and low levels can be adjusted according to actual conditions.

[0042] Step S202, applying each clock signal to the control end of the corresponding switch module, and applying the driving signal to the input end of each switch module, to control the plurality of first switch modules to be turned on in sequence and continuously, and in the case that the plurality of first switch modules are turned on in sequence and continuously, the display array displays the preset color, wherein the preset color is one of R, G, and B. In the case that the first switch module is turned on, the driving signal is at a first level. In the case that the second switch module is turned on, the driving signal is at a second level. One of the first level and the second level is low, and the other is high.

[0043] Specifically, according to formula 1, the greater the flip frequency f of the driving signal, the higher the power consumption of the IC, wherein formula 1 is as follows:

[0044]

[0045] Wherein, P is IC power consumption, f is the flip frequency of the driving signal, C is the capacitance, and U is the voltage. In some schemes, the number of display elements displaying preset colors in the pixel circuit is twice the number of display elements displaying each non-preset color, and when the display device displays a preset color (for example, a pure green screen, a pure red screen, or a pure blue screen), the flip frequency of the driving signal is f. For example, the number of display elements displaying red (R) and the number of display elements displaying blue (B) are both N, and the number of display elements displaying green (G) is 2N. At this time, the level of the driving signal is set to high-low-high-low, which can make the screen display a pure green screen. Alternatively, the number of display elements displaying red (R) and the number of display elements displaying green (G) are both N, and the number of display elements displaying blue (B) is 2N. At this time, the level of the driving signal is set to high-low-high-low, which can make the screen display a pure blue screen. Alternatively, the number of display elements displaying blue (B) and the number of display elements displaying green (G) are both N, and the number of display elements displaying red (R) is 2N. At this time, the level of the driving signal is set to high-low-high-low, which can make the screen display a pure red screen.

[0046] And on the basis of the above structure, the above method is used to control the switching module and each display element. In the case where the level of the driving signal is set to high-high-low-low, or low-low-high-high, or high-low-low-high, the screen can also display a pure color screen, and at this time the flip frequency of the driving signal is f / 2, which is half of the flip frequency of the driving signal before optimization, greatly reducing the power consumption of the display screen when displaying a pure color, improving the reliability of the module, and prolonging the standby time of the entire machine.

[0047] In some optional embodiments, the above-mentioned first switching module has two first and second switching tubes, the above-mentioned second switching module has two third and fourth switching tubes, the above-mentioned clock signal has four first, second, third, and fourth clock signals, the on levels of the above-mentioned first, second, third, and fourth clock signals are continuous in time domain, and the above-mentioned display elements have three types, namely first display elements displaying a first color, second display elements displaying a second color, and third display elements displaying a third color.

[0048] Wherein, one of the first color, the second color and the third color is red (R), another is green (G), and the last one is blue (B). In addition, by using different clock signals to control the opening and closing state of different switch tubes, whether the display element emits light can be controlled to a certain extent.

[0049] In addition, in the following embodiments, the odd column and the even column are defined according to the column of the display element arranged from left to right, and the odd row and the even row are defined according to the direction from far away from the switch module to close to the switch module.

The method combines the driving signal and the clock signal, controls the first switch module connected to the display element displaying the preset color to be continuously turned on in the time domain in the case that the display array displays the preset color, thereby reducing the level flip frequency of the driving signal, reducing the power consumption of the display screen when displaying pure color, and solving the problem that the power consumption of the display screen when displaying pure color is high due to the existing pixel circuit structure and clock signal.
