Just as described in the background section, existing display screen has that evenness degree is poor when showing picture.

Inventor is the study found that this is because existing display screen when carrying out aging process to its luminescence unit, mainly leads to The data input voltage on the data line for adjusting each luminescence unit electrical connection is crossed, the glow current of luminescence unit, Lai Shixian are increased To the premature aging of each luminescence unit.And for the luminescence unit of same color in same display screen, identical number is usually provided Aging process is carried out according to input voltage.

Inventor further study show that, existing display screen to its luminescence unit carry out aging process when, each luminous list Member shares same power voltage terminal, the formula I=K (PVDD-Data) of the glow current of each luminescence unit², wherein PVDD is hair The voltage of the power voltage terminal input for the display screen that light unit receives, Data are that the luminescence unit is received in aging process Data input voltage.When specific aging process, since luminescence unit each in display screen is different at a distance from power voltage terminal, make The voltage for obtaining the power voltage terminal input that each luminescence unit receives is different, as shown in Figure 1, Fig. 1 shows distance in display screen The luminescence unit of display screen bottom end different distance the input of received power voltage terminal voltage PVDD schematic diagram, wherein display The bottom end of screen is the position where the power voltage terminal of display screen.From figure 1 it appears that the hair closer apart from power voltage terminal The voltage of power voltage terminal that light unit receives input is bigger, and aging current is bigger, shines apart from power voltage terminal is remoter The voltage for the power voltage terminal input that unit receives is smaller, and aging current is smaller, is electrically connected so as to cause with same data line Multiple luminescence units of same color be electrically connected to identical power voltage terminal, and input identical data input voltage When, light emission luminance is different, and the display brightness apart from the closer luminescence unit of power voltage terminal is higher, farther out apart from power voltage terminal Luminescence unit display brightness it is relatively low so that the multiple luminescence units for the same color being electrically connected with same data line exist After the completion of aging process, life time decay difference is different, and the life time decay apart from the closer luminescence unit of power voltage terminal is larger, away from Life time decay from the farther away luminescence unit of power voltage terminal is smaller.

Moreover, existing display screen, when carrying out aging process to its luminescence unit, aging current for it by normally showing 4 times for showing the corresponding electric current of brightness, to further increase the longevity of the luminescence unit at power voltage terminal different location Order difference in attenuation.
