Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a display and drive method and device for rotating images through matrix transformation, so that the "horizontal screen" can meet the requirements of "vertical use" at the same time, and find another way to solve the problem of using existing OLED display screens for research and development and production. "Vertical screen" problem

Embodiment

[0031] The essence of the technical solution of the present invention is to rotate the image to be displayed by 90°, so that the original "upright" image becomes a "lying" image and displayed on the screen, and then rotate the screen by 90° in the direction opposite to the rotated image. °, make the "lying" image "upright" again, and complete the correct display of the input image. According to the technical scheme of the present invention, the display screen with A×B resolution can be used for driving and displaying B×A images. It can not only reduce the specifications and types of driving circuits and display screens, but also solve the technical problems in the development of some special display screens.

[0032] Such as figure 1 As shown, the input image 1 is a digital image with column B and row A, and its matrix expression is: B×A. From figure 1 It can be seen that the number of rows A in one image is greater than the number of columns B, that is, A>B, and the number...

Abstract

The present invention relates to a drive technology of a display screen of an organic light emitting diode and discloses an image matrix transformation drive method and a device thereof. The image matrix transformation drive method comprises the following steps: a. matrix transformation is carried out on an input image, so that the input image rotates 90 degrees on a plane; b. the rotated image is driven in a rank mode to be displayed on a screen; and c. the screen rotates 90 degrees towards the reverse direction of the rotated image. The image matrix transformation display device comprises a control system, the screen, a driver and an image rotation device, and is characterized in that the image rotation device is connected with the driver and used for rotating the input image by 90 degrees; the screen rotates 90 degrees is placed towards the reverse direction of the rotated image. The drive technology is mainly used for a display screen of OLED, particularly for the drive and display of PMOLED, can reduce the developed and manufactured kinds of the display screen, and is favorable for promoting the industrialized development of the display screen of OLED.

Description

technical field [0001] The invention relates to the drive technology of organic light-emitting diode display screens, in particular to the drive technology adopting digital image row-column matrix conversion. Background technique [0002] Among the flat-panel displays, the organic light-emitting diode (OLED) display is thinner and lighter, active light emitting, fast response, wide viewing angle, rich colors and high brightness, low power consumption, low temperature and high temperature resistance, excellent shock resistance, etc. Due to its many advantages, it is recognized by the industry as the third-generation display technology after liquid crystal display (LCD). Most of the large multinational companies in the world, including the IT industry, have invested huge sums of money to join the competition for OLED display technology. In terms of developing the OLED display industry, my country is currently standing on the same starting line as the world. Mastering OLED disp...
