Problems solved by technology

[0004] However, when the frequency of the data signal used is higher, the time for the data signal to be written into the corresponding pixel is shorter, which makes the pixel emit light when the data signal is not written enough, which easily leads to the problem of insufficient luminous brightness, thus affecting OLED display. The display effect of the device

Abstract

The invention discloses a signal control device and method, a display control device and method, and a display device, and relates to the field of display technology, which uses high-frequency data to drive the display device to display and improve the display effect of the display device. The signal control device includes k data lines corresponding to a column of pixel drive circuits, and each column of pixel drive circuits includes k type pixel drive circuits; the phase shifting unit makes the scanning signal phase difference of the adjacent two types of pixel drive circuits in the same column T / k, the write control unit controls the data signal terminal corresponding to the data write duration T of each pixel drive circuit i =T / k, the data writing start time difference between two adjacent types of pixel driving circuits is T / k; the signal matching unit controls the writing control unit to provide data signals to the pixel driving circuit receiving the scanning signal. The display control device includes the signal control device mentioned in the above technical solution. The signal control device provided by the invention is used in display technology.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a signal control device and method, a display control device and method, and a display device. Background technique [0002] The OLED display device is a display screen made of organic electroluminescent diodes, which has good self-luminous performance and display performance, and is considered to be an emerging application technology of the next generation of flat-panel displays. [0003] In the prior art, an OLED display device mainly includes a display control circuit and an OLED display substrate, and the display control circuit outputs matching scan signals and data signals to drive different pixels in the OLED display substrate by using the matched scan signals and data signals, thereby realizing OLED The screen display of the display device is displayed. When the OLED display device displays a picture, the data signal frequency used is relatively small (60 Hz), a...
