Detailed description of the invention
It is described in further detail below in conjunction with the drawings and specific embodiments proposition one OLED display to the present invention and aging method OLED display thereof and aging method thereof.Will be apparent from according to the following describes advantages and features of the invention.It should be noted that, accompanying drawing all adopts the form simplified very much and all uses non-ratio accurately, only in order to convenience, the purpose aiding in illustrating the embodiment of the present invention lucidly.
Existing OLED display panel is brightness disproportionation when burn-in test, it is impossible to reach shipment requirement.This is conducted in-depth research by inventor, the reason of brightness disproportionation is in that to find to cause existing OLED display panel to occur after weathering, supply voltage Vdd is walked the impact of line impedence by power supply and there is pressure drop (IRDrop), there is difference in the electric current making diverse location, simultaneously, in ageing process, the temperature of OLED display panel rises, and current difference and temperature impact cause OLED display panel obvious brightness disproportionation occur.
When pel array is more, power line is longer, and the pressure drop (IRDrop) of supply voltage Vdd is relatively larger, and the comparison in difference of the power supply signal being therefore actually reached pixel terminal is big.Particularly, near power end and big away from power supply signal comparison in difference between power end so that near power end and the electric current away from power end, notable difference occurs, in turn result in brightness irregularities.
If OLED display panel takes only from one end, pixel to be provided the mode of supply voltage Vdd, OLED display panel can be dimmed gradually.If taking the upper and lower two ends mode to pixel supply line voltage Vdd, whole OLED display panel presents upper and lower side dark situation bright, middle.Even if power line adopts network structure, the surrounding at pel array lays power line, and powering from four direction, it is bright also to form periphery, middle dark situation.
And, generally use big electric current time aging and light OLED display panel.Using big electric current to light OLED display panel can cause the temperature of OLED display panel to rise, and temperature impact can be further exacerbated by the brightness disproportionation of OLED display panel.
To sum up, existing OLED display panel reason of brightness disproportionation when burn-in test is caused to be in that, power supply cabling impedance influences is actually reached the supply voltage Vdd of pixel terminal, make the supply voltage Vdd being actually reached pixel terminal inconsistent, in turn result in current difference, cause brightness disproportionation, ageing process uses big electric current to light OLED display panel simultaneously, the temperature making OLED display panel rises, and has been further exacerbated by the aobvious brightness disproportionation of OLED.In order to solve the problems referred to above, present applicant proposes following technical scheme:
