Problems solved by technology

The screen door effect is when the pixels (screen and image) are insufficient, the thin lines dance caused by real-time rendering, and the high-contrast edges appear separate flickering phenomenon. It greatly affects the monochrome display perception and restricts the development of monochrome display devices

Embodiment Construction

[0058] In view of the display problems of the monochrome display device in the prior art, the inventor proposes that the display performance of the display device can be improved by increasing the resolution of the display panel. However, the resolution of the monochrome display device in the prior art is limited by the drive module, such as a drive chip, and the resolution of the pixels that can be driven by the drive chip in the prior art is limited, so that the resolution of the displayed image screen is the same restricted.

[0059] In a specific example, if the driving module can process image data with a resolution of 240*720, thereby generating a driving signal to drive each sub-pixel for display, at this time, the resolution of the image data to be processed received by the driving module is 240*720, the resolution of the image data that the drive module can process is 240*720, and the resolution of the finally displayed image screen for the user to watch is still 240*...

Abstract

The invention discloses a monochrome display driving method, a monochrome display driving module and a monochrome display device. The driving method of one embodiment is applied to a driving module of the monochrome display device, and the method comprises the following steps: compressing a plurality of received original image data to generate a plurality of gray scale information sets, each gray scale information set comprising a preset number of original image data; expanding the gray scale information set to obtain a plurality of monochromatic image data, the monochromatic image data being in one-to-one correspondence with pixels of the monochromatic display device; and generating a driving signal of each pixel according to the monochrome image data. According to the technical scheme, the resolution of the received original image data can be improved on the basis of not changing the driving performance of the driving module, so that the overall resolution of the display panel is improved, the display content watched by a user is clearer, the screen window problem is effectively solved, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of display technology. More specifically, it relates to a driving method for monochrome display, a driving module and a monochrome display device. Background technique [0002] Monochrome display devices have higher requirements on resolution than OLED display devices. Exemplarily, when the screen resolution of a smart phone is 1920×1080, the display image entering the human eye is very clear. However, if the display content is displayed by a monochrome display device with the same resolution, the The display content displayed by the magnifying module will be magnified. For example, the surface of white paper seen by human eyes is very smooth, but when viewed with a magnifying glass, it will be found that the surface of the paper is "cratered". [0003] In current monochrome display devices, the screen door effect has always been a huge problem. The screen door effect is when the pixels (screen and image) are insuf...
