Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.
The embodiment of the present invention provides a kind of method of stable display of organic electroluminescence brightness, and described display comprises the sub-pixel of three kinds of primary colours of red, green, blue, and as shown in Figure 2, described method comprises:
It should be noted that, existing display of organic electroluminescence at least comprises the sub-pixel of three kinds of different colours, i.e. the luminescence unit corresponding to luminophor of three kinds of different colours of red, green, blue.Certainly, display of organic electroluminescence can also be the sub-pixel that comprises multiple different colours, for example, can be the sub-pixel that comprises red, green, blue, Bai Si kind different colours, can also be the sub-pixel that comprises red, green, blue, Huang Si kind different colours.But no matter the color of the sub-pixel that display comprises has multiplely, and it includes the sub-pixel of three kinds of primary colours of red, green, blue, and the different color of display is all formed by harmonic proportion by three kinds of primary colours of red, green, blue.The embodiment of the present invention be take sub-pixel that described display of organic electroluminescence comprises three kinds of different colours of red, green, blue and is elaborated as example, it is the sub-pixel that each pixel cell comprises three kinds of different colours of red, green, blue, the shades of colour that display shows is mixed to form through a certain proportion of by the sub-pixel of three kinds of different colours of red, green, blue, by adjusting the sub-pixel of different colours, can also further adjust the white balance of display.The method that the embodiment of the present invention provides compensates respectively the sub-pixel of display different colours according to the relation of the brightness of the sub-pixel of different colours and displaying time.
It should be noted that, as shown in Figure 3, because the brightness of sub-pixel of different colours is different with the relation curve of displaying time, as can be seen from Figure 3, the decay of green sub-pixels 1 is the slowest, and the decay of red sub-pixel 2 is taken second place, and decaying the fastest is blue subpixels 3.The Benchmark brightness of the sub-pixel of display different colours is interval different, respectively the sub-pixel of different colours is carried out to different compensation, thereby can guarantee the white balance of display.By adjusting data voltage so that the brightness showing is compensated, and by improving the data voltage of the sub-pixel of different colours, the brightness that further can improve the sub-pixel of different colours; By reducing the data voltage of each sub-pixel, can reduce the brightness of the sub-pixel of different colours.
Described Preset Time interval can be at least one interval of dividing according to the predicted life of display.For example the mission life of display is time of 50% that original intensity is arrived in brightness decay, and generally ideally, the mission life of display is more than 30,000 hours (with OLED display work for 10 years, calculate 8 hours every days).Described Preset Time interval can be 10 years, i.e. the General Life of display.Described Preset Time interval can be also 1 year, according to the General Life of display, is divided into 10 Preset Time intervals.Certainly, can also specifically set its default time interval according to the service condition of display.And it is 10 years that the embodiment of the present invention be take life-span of display, is divided into 10 Preset Time intervals, each Preset Time interval is to be elaborated for example for 1 year.Described display shows and makes the sub-pixel of display different colours show in a stable brightness range in the brightness range in Benchmark brightness interval, make display show in a stable brightness range, and by the sub-pixel of different colours being compensated to the white balance that can further guarantee display.It can be by adjusting data voltage so that the brightness of the sub-pixel of different colours is compensated that the described sub-pixel to display different colours compensates.It should be noted that, because the demonstration of display realizes by each sub-pixel, the displaying time of display is the displaying time of the sub-pixel of different colours.
The method of a kind of stable display of organic electroluminescence brightness that the embodiment of the present invention provides, according to the relation of the brightness of the sub-pixel of different colours and displaying time, the sub-pixel of display different colours is compensated respectively, the displaying time that makes described display is in Preset Time interval range time, the sub-pixel of different colours shows in the brightness range in Benchmark brightness interval, thereby stablizes the display brightness of display.

The displaying time of statistics display can complete by timer.Concrete, when the supply voltage conducting of display, described timer starts timing; When the supply voltage of display is closed, described timer stops timing.Certainly, the displaying time of statistics display, can also complete by other means.
Because the demonstration of display realizes by each sub-pixel, the displaying time of adding up display adds up the working time of each sub-pixel.
Optionally, as shown in Figure 5, above-mentioned steps 101, describedly according to the relation of the brightness of the sub-pixel of different colours and displaying time, the sub-pixel of display different colours is compensated specifically and is comprised respectively:
Concrete, described Preset Time interval can be at least one interval of dividing according to the display life of display.In the embodiment of the present invention, the general display mission life ideally of take is example, is divided into 10 Preset Time intervals.Each Preset Time interval is 1 year, then by described Preset Time interval division, is further 12 Preset Time sub-ranges, and be a Preset Time sub-range January.
As shown in Figure 6, take blue subpixels as example, it is example that the working time of the blue subpixels in one of them Preset Time interval and brightness curve close, in Fig. 6, brightness in the time interval of Tx to Tx+2 becomes power function decay, working time and the working curve of blue subpixels under ideal situation of take is example, in the time interval of Tx to Tx+2, corresponding brightness decays to Lx+2 from Lx according to 5% down ratio, the interval Tx to Tx+2 of Preset Time is divided into 12 Preset Time sub-ranges, setting original intensity penalty coefficient is 98.32%, and according to 0.42% progressive law increase progressively for penalty coefficient be 102.52%, the penalty coefficient that is the first six Preset Time sub-range is followed successively by 97.48%, 98.32%, 98.74%, 99.16%, 99.58% and 1, the penalty coefficient in rear six Preset Time sub-ranges is followed successively by 100.42%, 100.84%, 101.26%, 101.68%, 102.1% and 102.52.12 Preset Time sub-ranges compensate with the penalty coefficient of presetting.
It should be noted that, in above-described embodiment, with generally ideally, the mission life of display is more than 30,000 hours (with OLED display work for 10 years, calculate 8 hours every days).The i.e. brightness decay 50% of 10 years blue subpixels, annual mean flow rate rate of change is 5% (rate of change 50%/10 year), monthly mean flow rate rate of change is to be 0.42% (5%/Dec of rate of change) example.Above-described embodiment be take 1 year as a Preset Time interval, by described Preset Time interval division, is 12 Preset Time sub-ranges, within one month, is that a Preset Time sub-range is example.Its concrete penalty coefficient can also change as required, and for example in above-described embodiment, the penalty coefficient in the 6th of 12 Preset Time sub-ranges the Preset Time sub-range is 1, and the penalty coefficient that the 7th Preset Time sub-range can also be set is 1; Or odd number Preset Time sub-range is set and arrange in the middle of the penalty coefficient in Preset Time sub-range be 1.And according to the intrinsic brilliance of display, change, the penalty coefficient in above-mentioned each Preset Time sub-range can also be different.The present invention only be take and is above-mentionedly elaborated as example.
The working time of the blue subpixels in Preset Time interval and brightness curve relation are not the power function decay shown in Fig. 6, with reference to said method, determine the penalty coefficient in each Preset Time sub-range according to concrete attenuation law.Concrete can and determine attenuation coefficient die-away time according to the decay difference of brightness, then in conjunction with relation curve and then definite penalty coefficient of concrete displaying time and brightness.
It should be noted that, the compensation method of the sub-pixel of other colors is identical with the compensation method of blue subpixels, just the displaying time of the sub-pixel of different colours is different from brightness curve relation, and its concrete compensation can compensate with reference to above-mentioned compensation method with concrete compensated curve.

Concrete, as shown in Fig. 3, Fig. 6, according to the displaying time of blue subpixels 3, can correspondingly obtain high-high brightness Lx and the minimum brightness Lx+2 in the Preset Time interval range of Tx to Tx+2 with the relation of brightness.
According to the high-high brightness Lx in the Preset Time interval range of the Tx to Tx+2 obtaining and minimum brightness Lx+2, can obtain the mean flow rate Lx+1 of the blue subpixels in the Preset Time interval range of the interval Tx to Tx+2 of Preset Time.
Concrete, as shown in Figure 8, the displaying time of blue subpixels in the Preset Time interval range of Tx to Tx+2 and the relation curve of brightness, the high-high brightness of the blue subpixels in the Preset Time interval range of Tx to Tx+2 is that Lx, minimum brightness are that its mean flow rate of Lx+2(is Lx+1.Relation curve and the corresponding compensated curve 4 that obtains brightness of mean flow rate according to the displaying time in Preset Time interval range with brightness.
Above-mentioned according to the compensated curve of blue subpixels to blue subpixels compensate can so that the blue subpixels of display with described mean flow rate, show.It should be noted that in addition, when the sub-pixel of display different colours is compensated respectively, to make it take the Preset Time interval the longest that described mean flow rate arranges while showing be 1 year.
It should be noted that, the compensation method of the sub-pixel of other colors is identical with the compensation method of blue subpixels, just the displaying time of the sub-pixel of different colours is different from brightness curve relation, and its concrete compensation can compensate with reference to above-mentioned compensation method with concrete compensated curve.
