Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
OLED pixel drive circuit whether voltage-programming, or current programmed, or two kinds of hybrid programming modes, OLED
Luminosity is dependent on thin film transistor (TFT), and (Thin Film Transistor are referred to as：TFT) driving current, and size of current
Determine power consumption size simultaneously.For example on display the driving current/power consumption in some region is bigger, and the temperature at this is also got over
Height, causes to drive rise TFT rate of ageing moment short time.That is, rate of ageing of the high-brightness region than low brightness area
Hurry up, the difference of visual spatial and temporal distributions occurs in the final brightness for causing display screen, so appear in static images switching with
High-brightness region is dimmed afterwards and situation that low brightness area brightens, influences image quality.
The technical problem existed for prior art, the present invention proposes a kind of self-emitting display and self-emitting display
Display methods.The method that the present invention is provided is applied to the benefit for entering trip temperature and mobility to self-luminous class such as OLED display
Repay, so as to avoid the problem of rate of ageing is different, be particularly suitable for static images or part static state display content such as film mould
Black surround under formula.This method is to do to compensate in real time when OLED is normally shown, does not interfere with the content of actual displayed, such as bright
Degree, contrast, saturation degree etc..
By OLED display in film mode exemplified by, except show normal pictures in addition to, more than former normal pictures surrounding
Black surround, this black surround is due to that raw frames are different from the display size specification of display, is caused after conversion, Fig. 1 is shown
16:9 raw frames are 4:Schematic diagram after 3 display size conversion.Although some existing playout softwares can remove black surround,
But the displaying ratio distortion of image can be caused.In order to keep the content of original raw frames consistent on different displays
Property, keep black surround that there is practical significance, particularly be frequently necessary to show as the display pattern shown in Fig. 1 under some film modes.
But it is in long-time under the above-mentioned display pattern with black surround, because the pixel in black surround region does not work, causes this
The temperature in region is relatively low, and the temperature of viewing area is higher so that the driving TFT in this two regions short time aging tendency
It is different.When switching to other pictures, easily there is black surround and brighten, and the dimmed situation in viewing area.Therefore, believe for image
Number, it is necessary to corresponding compensation is done to black surround region, to improve image display quality, and user satisfaction.
The technical scheme of the application can solve above-mentioned black surround viewing area and image display area aging occur uneven
The problem of, namely the problem of appearance visual spatial and temporal distributions difference, general thought is as follows：
Due to the main cause for producing drawbacks described above be operating voltage between the sub-pixel of same type it is inconsistent thus
Brightness decay size during display is also different to be caused, and the operating voltage that this programme passes through image display area pixel determines
The gray scale voltage of pixel in black surround region, so that black surround regional work is under the gray scale voltage, and passes through the picture to black surround region
The corresponding driver' s timing of plain circuit is modified so that the luminescent device in black surround region does not light, and then image is shown
Rate of ageing in area pixel and black surround region between pixel reaches unanimity, and eliminates the problem of aging is uneven, improves use
The satisfaction at family.

During the second row pixel, namely during T2, the corresponding SEL1 of the second row pixel is high level (not shown), and the first row pixel pair
The SEL1 answered switches to low level, so now the corresponding first switch transistor 1031 of the first row pixel is turned off, and due to
The corresponding second switch transistor 1032 of the first row pixel is in strobe state, and detection line is similarly in high level state, institute
With detection line and VDATABetween form path, and then, storage capacitance 1034 electric discharge open driving transistor 1033, cause the row picture
Element work, but due to detection line and VDATABetween form path, so luminescent device 1035 is short-circuited, namely luminescent device 1035
Do not work, although now the image element circuit 103 has operating voltage to be still shown as black, wherein, VDATAFor in display data
Hold corresponding gray scale voltage, it reacts the charge volume of storage capacitance 1034, the charge volume discharge band is carried out driving transistor 1033 and opened
Open the time, i.e. the working time of luminescent device 1035, show as the pixel display brightness, luminance integration reacts display image content,
But because luminescent device 1035 is short-circuited, so luminescent device 1035 does not work, although now the image element circuit 103 has work electricity
Pressure ought still be shown as black.That is, in compensation model, the second switch transistor 1032 in image element circuit 103 is gating
State.
Above-mentioned luminescent device 1035 is Organic Light Emitting Diode OLED.
The image element circuit in the black surround region that the present embodiment is provided, can control pixel by SEL1 and SEL2 output level
Whether the device of giving out light in circuit is lighted, and when SEL2 is high level, the luminescent device in image element circuit is short-circuited, so that
Image element circuit is obtained to work under gray scale voltage, and the luminescent device in image element circuit does not light so that the aging speed in black surround region
The rate of ageing of rate and image display area reaches unanimity, and improves image displaying quality and the satisfaction of user.
