Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Please refer to figure 2 , figure 2It is a schematic diagram of a control register set according to an embodiment of the present invention. The interface selector is used to select the currently effective interface: when S_PB is high level, select the MCU interface as the currently effective interface; when S_PB is low level, select the SPI interface as the currently effective interface; when ena_RGB is high level , select the RGB interface as the effective interface; when ena_RGB is at low level, the RGB interface is invalid, and the timing controller provides the vertical and horizontal synchronous signals at this time. Take S_PB high level as an example, at this time, the external host sends image data or commands through the MCU interface. The interface selector selects 4 signals of the MCU interface as output: clk clock signal...

Abstract

The invention relates to the field of an organic light-emitting diode display technology, discloses a white balance adjustable AMOLED display driver, and brings forward a white balance adjustable AMOLED display driver, for solving the disadvantage that a conventional AMOLED display driver can only support display of a single while balance point. The driver has two display modes: a D65 mode and a D93 mode. When the white balance point of an image is D65, the display driver works at the D65 mode; and when the white balance point of the image is D93, the display driver works at the D93 mode. Therefore, the driver provided by the invention can adjust the display mode of the display driver according to the white balance point of the image so as to realize a better display effect.

Description

technical field [0001] The invention relates to the field of organic light-emitting diode display technology, in particular to an AMOLED display driver with adjustable white balance. Background technique [0002] AMOLED (Active-matrixorganiclight-emittingdiode, active-matrix organic light-emitting diode) is a display technology widely used in TVs and mobile devices. Where AM means that the organic light-emitting display device (OLED) is an active light-emitting device. Compared with the current mainstream flat-panel display technologies such as thin-film transistor liquid crystal displays, OLED has the advantages of high contrast, low power consumption, wide viewing angle, and thin volume. It is one of the most concerned technologies in flat-panel display technology. [0003] The white displayed by AMOLED is synthesized by the three primary colors of red, green and blue, and the corresponding white balance can be obtained by adjusting the brightness ratio of red, green and ...
