S202 controls the white light-emitting diode shared and shines.
One pixel of spontaneous optical arrays includes multiple non-white luminous points and white luminous point, and in the present embodiment, when arranging spontaneous optical arrays, the white luminous position that two or more pixels can be set is adjacent.As Fig. 6 is exemplary share white light-emitting diode spontaneous optical arrays arrange schematic diagram, red, blue, green, white four luminous points constitute a pixel, in the left figure of Fig. 6, the white luminous position of pixel A and pixel B is adjacent, is correspondingly arranged one under the white luminous point of pixel A and pixel B
The white luminous point of a white light-emitting diode, i.e. pixel A and pixel B shares a white light-emitting diode, controls the white light-emitting diode shared and shines, and in left figure, colour resolution is L × K, and white resolution ratio is L/2 × K；In the right figure of Fig. 6, the white luminous position of pixel A, B, C, D are adjacent, a white light-emitting diode is correspondingly arranged under the white luminous point of pixel A, B, C, D, that is the white luminous point of pixel A, B, C, D shares a white light-emitting diode, the white light-emitting diode shared is controlled to shine, in right figure, colour resolution is L × K, and white resolution ratio is L/2 × K/2.
By taking 400x400x24bit shows the OLED display screen of specification as an example, under normal mode, the image that display image is 400x400x24bit, actual light emitting pixel points are M, and practical light-emitting LED number is 3M, and M is positive integer；And under low-power consumption mode and when realizing that white luminous point shines using the non-white light emitting diode combined of multiple and different colors, show that image is 256 gray scale images of 400x400, and by the way that Background is set as completely black, practical light emitting pixel points are reduced to N, reality is light-emitting LED to be reduced to 3N, and wherein N is positive integer and N < M；And in the present embodiment, low-power consumption mode and controls the adjacent multiple pixels in white luminous position and share a white light-emitting diode and shine, such as adjacent four pixels of white luminous point share a white light-emitting diode, if the white luminous point of every four pixels is all adjacent in entire spontaneous optical arrays, adjacent white luminous point shares a white light-emitting diode, then actual leds are N/4 light emitting diode, it is compared than original technology, 1/12 light emitting diode is only used, reduce light emitting diode quantity, it further reduced display screen power consumption.
Still by taking Fig. 6 as an example, in order to reach the reduction of different degrees of power consumption, it can be reduced to different white resolution ratio, according to the difference of the white resolution ratio of reduction, using the arrangement of different spontaneous optical arrays.
Setting greyscale level is realized in S203, the brightness for adjusting the white light-emitting diode.
Gray scale image is different grades according to light emission luminance different demarcation, generally there is 256 grades, and therefore, the brightness of adjustable white light-emitting diode sets different greyscale levels to realize.
S204 sets completely black for the background of described image.
Here, when spontaneous optical arrays work is under low-power consumption mode, display screen shows gray scale image, sets completely black for the background of image and refers to that the other non-white light emitting diodes controlled in pixel do not shine in control pixel in addition to needing luminous white luminous point to shine.The background of image is set as completely black, black pixel point can be increased, for spontaneous optical arrays, can effectively reduce and need luminous pixel quantity, to further decrease the power consumption of display screen.
A kind of spontaneous optical arrays display control method provided according to embodiments of the present invention is sent out by using white
