A digital scanning circuit

Abstract

The invention discloses a digital scanning circuit, comprising: a video source module, a bit fusion module, a buffer module and a silicon-based organic light emitting diode panel, which are connectedin sequence, wherein the video source module is used for transmitting two consecutive images; the bit fusion module is used for performing low-bit fusion on the data information of the two consecutiveimages sent by the video source module to obtain fused data information; and the buffer module is used for buffering and storing the fused data information. The digital scanning circuit disclosed bythe invention, the scanning efficiency can be improved without adding additional clock frequency, and the transmission bandwidth can be maximally used, so that the purpose of improving the image resolution is achieved.

Description

technical field [0001] The invention relates to the field of digital scanning, in particular to a digital scanning circuit. Background technique [0002] At present, the research image gray scale of related silicon-based organic light-emitting diode microdisplays is 256 levels, and the resolution is usually 640*320 resolution stage, which cannot show the details of darker or brighter images, and only a few products can reach 1920* 1280 resolution level, the main reason is that the scanning imaging technology is limited by the thinking of traditional electron gun scanning, and the scanning principle is based on point-by-point scanning and top-to-bottom order, which has a lot of time redundancy, resulting in loss of brightness and gray scale . As a result, the clock frequency of the core computing entity increases exponentially as the gray level increases, and the cost and power consumption of the system increase accordingly. If it is necessary to increase the gray scale of ...

[0002] At present, the research image gray scale of related silicon-based organic light-emitting diode microdisplays is 256 levels, and the resolution is usually 640*320 resolution stage, which cannot show the details of darker or brighter images, and only a few products can reach 1920* 1280 resolution level, the main reason is that the scanning imaging technology is limited by the thinking of traditional electron gun scanning, and the scanning principle is based on point-by-point scanning and top-to-bottom order, which has a lot of time redundancy, resulting in loss of brightness and gray scale

As a result, the clock frequency of the core computing entity increases exponentially as the gray level increases, and the cost and power consumption of the system increase accordingly.

If you want to increase the gray scale of the displayed image, the hardware performance and scale will be greatly increased, and the miniaturization design of the display cannot be used, and the goal of reducing power consumption cannot be achieved.
