Optionally, the greyscale level of the green sub-pixels of raising is greater than the greyscale level of the red sub-pixel of raising.
As shown in Figure 1, due to slower with respect to red sub-pixel 2 decay of green sub-pixels 1, can be arranged so that the greyscale level of the green sub-pixels of raising is greater than the greyscale level of the red sub-pixel of raising, so that the decay of green sub-pixels and red sub-pixel is consistent.Concrete, the sub-pixel of different base colors of the display shown in Fig. 1 of take is example with the attenuation relation of displaying time.Green sub-pixels 1 decay is the slowest, can improve 48 greyscale level; Red sub-pixel is very fast compared to green sub-pixels decay, can improve 24 greyscale level, so that the decay of green sub-pixels and red sub-pixel is consistent.Below the display of all take comprises that 256 GTGs are that 255 greyscale level are example.Certainly, according to the difference of the sub-pixel of display, can also the different classes of attenuation be set according to different situations, the embodiment of the present invention only be take and is above-mentionedly elaborated as example.
The poor greyscale level that is greater than red sub-pixel of the greyscale level of green sub-pixels can also be set poor.Display comprises that 256 greyscale level are example, and greyscale level is poor is 1.According to the sub-pixel of the different base colors of display, with the brightness decay relation of displaying time, greyscale level is set poor, i.e. green sub-pixels decay is the slowest, and the rank difference that green sub-pixels can be set is larger, for example, can be 8.Red sub-pixel decay is taken second place, and the rank difference that red sub-pixel can be set is less than the rank difference of green sub-pixels, for example, can be 6.Ought arrange like this in the situation that green sub-pixels is identical with the demonstration GTG of red sub-pixel raising, the display brightness of the actual raising of green sub-pixels is greater than the display brightness of the actual raising of red sub-pixel, thereby makes the decay of red sub-pixel and green sub-pixels consistent.
Optionally, as shown in Figure 6, described method comprises:
The driving frequency of step 104, increase display, makes described display in Preset Time interval, comprise at least two display cycles.
Because human eye is relevant with frequency, concrete for the impression of brightness, when display brightness is constant, only increase the driving frequency of display, the brightness of the actual impression of human eye will be lower than display brightness.On the basis of driving frequency that increases display, can also further improve or reduce GTG value, the decay that can accelerate or reduce or remit corresponding sub-pixel.In addition, increase driving frequency, the too large display distortion of GTG value that can avoid display to improve or reduce.
It should be noted that there is no certain precedence relationship between above-mentioned steps 104 and other steps, the embodiment of the present invention only be take and before above-mentioned steps 101, is carried out step 104 as example.
Further, as shown in Figure 7, described method comprises:
The driving frequency of step 104, increase display.
The driving frequency that increases display, makes described display in Preset Time interval, comprise at least two display cycles.
In the different display cycles, described same view data is converted to the different GTG values corresponding with sub-pixel difference in described each pixel cell, the GTG value that makes same sub-pixel reduce or improve in the different display cycles is different.
Concrete, the twice that the driving frequency that increases display is normal display frequency, half that its display cycle is the normal display cycle, comprises two display cycles.The GTG value that now can be arranged on one of them display cycle is constant, improves or reduce the GTG value of another display cycle.Or, improve or reduce simultaneously the GTG value of two display cycles, but it is identical or different that the demonstration GTG value that improves or reduce is set.Specifically can be by described same view data being converted in the different display cycles to the different GTG values corresponding with sub-pixel difference in described each pixel cell, the GTG value that makes same sub-pixel reduce or improve in the different display cycles is different.
By increasing display frequency and the demonstration GTG of adjustment display cycle of display, can reduce the monochromatic change color showing of display that human eye is experienced, further improve display effect.
Need the above raising of explanation or the demonstration GTG of reduction, all described in step 102, each pixel cell in the first area that shows image is only during drive point sapphirine sub-pixel, described by described view data be converted to sub-pixel in described each pixel cell respectively corresponding GTG value be specially: the corresponding GTG value that reduces the described blue subpixels of described first area; And/or, each pixel cell in the image showing in second area is only during drive point shiny red sub-pixel, described by described view data be converted to sub-pixel in described each pixel cell respectively corresponding GTG value be specially: improve GTG value corresponding to red sub-pixel described in described second area; And/or, in the 3rd region of the image showing, each pixel cell is only during drive point bright green sub-pixel, described by described view data be converted to sub-pixel in described each pixel cell respectively corresponding GTG value be specially: improve described the 3rd region corresponding described in GTG value corresponding to green sub-pixels.
Certainly, the driving frequency that display can also be set is normal display frequency three times etc., the embodiment of the present invention only be take to be increased twice that the driving frequency of display is normal display frequency and is elaborated as example.
