Problems solved by technology

[0007] 1. The brightness utilization rate decreases. For example, a certain point of a frame image is the brightest in 60 consecutive frames, and the brightness value is assumed to be 255. However, due to the interval time caused by changing frames, only 1 second is displayed. 900 milliseconds, the brightness loss is 10%
[0008] 2. The current is large and the power consumption is large. If it needs to reach a certain brightness level, the entire LED display will lose more power

Embodiment approach

[0035] refer to image 3 , image 3 It is a flowchart of an embodiment of an image display method in the present invention. The embodiment of the present invention comprises the following steps:

[0036] Step S11 , alternately read frame original images from at least two storage areas according to the frame original image display order, and respectively serve as the previous frame original image and the next frame original image.

[0037] Wherein, each frame of image is displayed normally, that is, before the frequency doubling process is performed on each frame of image, the frame of image is defined as the frame original image.

[0038] In step S11, a ping-pong operation is adopted for displaying the original frame image. Specifically, taking the storage area including the first storage area and the second storage area as an example, the two frame original images are correspondingly stored in the first storage area and in the second storage area, define the two frame orig...

Abstract

The invention discloses an image displaying method, a driving device and a displaying system. The method comprises the steps of alternately reading frame original images from at least two storage regions according to frame original image displaying sequences and enabling the frame original images to serve as a front frame original image and a next frame original image respectively; working out frequency doubling numbers, needing frequency doubling processing, of the frame original images according to predetermined rules; and conducting frequency doubling processing on the front frame original image, at least obtaining a plurality of complete front frame frequency doubling images and one incomplete front frame frequency doubling image, conducting frequency doubling processing on the next frame original image, at least obtaining a plurality of complete next frame frequency doubling images and one incomplete next frame frequency doubling image, and enabling a total frequency doubling number of all front frame frequency doubling images and all next frame frequency doubling images to be equal to a total frequency doubling number of the front frame original image and the next frame original image. By means of the mode, the problems of black strips and water ripples are solved, luminance utilization rate is improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of LED display devices, in particular to an image display method, a driving device and a display system. Background technique [0002] The principle of image playback is the same as that of LCD and other display devices. According to the vision of the human eye, multiple frames of images per second are required to be played continuously to complete the display, so that the continuity of image playback can be felt, otherwise the screen will flicker. [0003] In the display, there is an intermittent time between frames. Because the display uses CCFL and other backlight methods for light emission, even if there is no new data during this period, the deflection angle of the liquid crystal molecules remains unchanged, and the image continues to be displayed. The color and brightness of the LED display are completely represented by the LED switching time. If the LED is turned off, the screen will not display image...
