Embodiment 1

[0032] According to an embodiment of the present invention, an embodiment of an LED display screen is provided. Figure 4 The pixel unit array of the LED display is shown, and the enlarged view of each pixel unit A is shown in Figure 5 shown.

[0033] Figure 5 shown in pixel cell A with figure 2Compared with the pixel unit A' of the prior art shown, the LED display screen in this embodiment has two display units, namely the first display unit A1 and the second display unit A2. The two display units adopt the same structure, and each display unit has an independent color matching, which can be red, green and blue, or other color ratios, and examples are not given here. Since the two display units adopt the same color matching, the pixel unit becomes a unit of double color matching, therefore, the two units can emit light independently or simultaneously. In the case that one display unit fails to emit light, another display unit can be used to emit light; or, in the case ...

Embodiment 2

[0049] According to an embodiment of the present invention, an embodiment of a display control method of an LED display is provided. The display control method of the LED display can control the LED display in Embodiment 1. The LED display in Embodiment 1 This display control method can also be used for control. It should be noted that the steps shown in the flowcharts of the accompanying drawings may be performed in a computer system, such as a set of computer-executable instructions, and that although a logical order is shown in the flowcharts, in some cases, The steps shown or described may be performed in an order different than here.

[0050] Figure 11 It is a flowchart of a display control method for an LED display screen according to an embodiment of the present invention, the display screen includes a plurality of pixel units, and each pixel unit includes a first display unit and a second display unit, such as Figure 11 As shown, the method includes the following s...

Abstract

The invention discloses an LED display screen and a display control method thereof. The LED display screen comprises a pixel unit and a control unit, wherein the pixel unit comprises a first display unit and a second display unit, and the control unit is respectively connected with the first display unit and the second display unit, and is used for controlling the first display unit and / or the second display unit to emit light so that the pixel unit emits light according to the preset rules. With the adoption of the LED display screen and the display control method thereof, the technical problem of the screen image missing caused by the damage of the pixel unit is solved.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to an LED display screen and a display control method thereof. Background technique [0002] Existing LED display screens are composed of multiple LED pixel units, and each LED pixel unit displays a corresponding color after receiving a signal. figure 1 is the front view of the LED display screen of the prior art, figure 2 yes figure 1 The enlarged view of A' in Fig. 1 shows a display unit contained in a pixel unit A'. image 3 It is the rear view of the LED display screen in the prior art, B' is a driver chip array, 11' is the data input end, 12' is the power input end, 13' is the data output end, image 3 The driver chip shown and figure 1 The pixel units shown are set on both sides of a PCB board and controlled by the driver chip figure 1 The pixel units of the LED display screen shown emit light, thereby realizing the image display of the LED display screen. [0003] Depend on figure...
