Embodiment 1

[0055] refer to figure 2 , which shows a flow chart of a display control method in Embodiment 1 of the present invention, which may specifically include the following steps:

[0056] Step 201, acquire the actual chromaticity coordinates of the current mixed color sub-pixel light.

[0057] In the embodiment of the present invention, the mixed color sub-pixel is a white sub-pixel, and when the white OLED device ages, the chromaticity coordinates of the white sub-pixel light will shift, so that the white sub-pixel light contains a certain proportion of the basic color sub-pixel light .

[0058] The basic color sub-pixels are red sub-pixels, green sub-pixels, and blue sub-pixels, and the mixed color sub-pixels are white sub-pixels; or the basic color sub-pixels are yellow sub-pixels, blue sub-pixels, and the The mixed color sub-pixels are white sub-pixels. White light can be obtained by mixing red light emitted by red sub-pixels, green light emitted by green sub-pixels, and bl...

Embodiment 2

[0079] refer to image 3 , which shows a flow chart of a display control method according to Embodiment 2 of the present invention, which may specifically include the following steps:

[0080] Step 301, acquire the actual chromaticity coordinates of the current mixed color sub-pixel light.

[0081] This step is similar in principle to step 201 in Embodiment 1, and will not be repeated here.

[0082] Step 302 , measuring the actual chromaticity coordinates of the light of the basic color sub-pixel under the current lifetime index of the white OLED device corresponding to the current basic color sub-pixel.

[0083] In the embodiment of the present invention, the basic color sub-pixels are red sub-pixels, green sub-pixels, and blue sub-pixels. Measure the light intensity of the basic color sub-pixels under the current lifetime index of the white OLED device corresponding to the current basic color sub-pixels. The actual chromaticity coordinates, that is, the actual chromaticity...

Embodiment 3

[0103] refer to Figure 4 , shows a structural block diagram of a display control device according to Embodiment 3 of the present invention.

[0104] The display control device 400 of the embodiment of the present invention includes:

[0105]The chromaticity coordinate acquisition module 401 is configured to acquire the actual chromaticity coordinates of the current mixed color sub-pixel light.

[0106] A ratio calculation module 402, configured to calculate the proportion of the basic color sub-pixel light in the mixed-color sub-pixel light according to the actual chromaticity coordinates of the mixed-color sub-pixel light and the chromaticity coordinates of the basic color sub-pixel light. proportion.

[0107] A target luminance data determining module 403, configured to determine the mixed color sub-pixel according to the initial luminance data of the basic color sub-pixel and the proportions of the basic color sub-pixel light in the mixed color sub-pixel light and the t...

Abstract

The invention provides a display control method and device and a display device, and relates to the technical field of display. According to the display control method, actual chromaticity coordinates of sub-pixel light of a current mixed color are obtained, according to the actual chromaticity coordinates of the sub-pixel light of the current mixed color and chromaticity coordinates of sub-pixel light of basic colors, the proportion of the sub-pixel light of each basic color accounting for the sub-pixel light of the mixed color is calculated, and according to initial luminance data of sub-pixels of the basic colors and the proportion of the sub-pixel light of each basic color accounting for the sub-pixel light of the mixed color, target luminance data of the sub-pixels of the basic colors and target luminance data of sub-pixels of the mixed color are determined. The sub-pixels of the mixed color are sub-pixels of white, when a white OLED device ages, chromaticity coordinates of the sub-pixels of white are deviated, according to the proportion of the sub-pixel light of each basic color accounting for the sub-pixel light of white and the initial luminance data of the sub-pixels of the basic colors, the target luminance data of the sub-pixels of the basic colors and target luminance data of sub-pixels of white are determined, so that final display colors of an image is not deviated.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display control method, device and display device. Background technique [0002] Active Matrix Organic Light Emitting Diode (AMOLED) display device, as a next-generation display device, has attracted great attention because of its fast response speed, high luminous efficiency, high brightness and wide viewing angle. The display device displays images by controlling the current flowing in the OLED by driving the transistor. [0003] refer to figure 1 , shows a schematic structural view of an existing white OLED display device, a white OLED (Organic Light Emitting Diode, organic light emitting diode) display device can achieve full color through a white OLED (WOLED) device plus color filters of RGB three colors show. A white OLED display device has a plurality of pixels, and each pixel includes a red sub-pixel for generating red light, a green sub-pixel for generating...
