Problems solved by technology

However, in the existing large-size organic light-emitting diode display devices, the pulse signal is relatively complete at the initial stage of input, and when it is transmitted to the far end of the wiring, the pulse signal gradually attenuates, resulting in the display device corresponding to the signal input end The display brightness is high, but the display area corresponding to the far end of the wiring is insufficiently charged due to signal attenuation and the brightness is low. question

Abstract

The invention provides an organic light-emitting diode display device. The organic light-emitting diode comprises a plurality of organic light-emitting diode light-emitting units. A first side outputterminal is configured to output a first pulse signal. A second side output terminal is configured to output a second pulse signal. The second side output terminal is disposed on the other side different from the first-side output terminal. A plurality of columns of signal lines is connected with at least one organic light-emitting diode light-emitting unit. The plurality of columns of signal lines are arranged side by side. The odd-numbered columns of signal lines are connected to the first-side output terminal, wherein the signal lines in the even-numbered columns are connected with the second side output terminal. The organic light-emitting diode light-emitting unit is configured to emit light according to the first pulse signal or the second pulse signal, so that the brightness difference between the edge and the middle area of a display picture is eliminated. The brightness uniformity of the display picture is improved.

Description

【Technical field】 [0001] The disclosure relates to the field of display technology, in particular to an organic light-emitting diode display device for improving poor display partitioning. 【Background technique】 [0002] Active matrix organic light-emitting diodes are expected to replace liquid crystals for next-generation displays due to their high contrast ratio, wide viewing angle, and fast response speed. However, in the existing large-size organic light-emitting diode display device, the pulse signal is relatively complete at the initial stage of input, and when it is transmitted to the far end of the wiring, the pulse signal gradually attenuates, resulting in the display device corresponding to the signal input end The display brightness is high, but the display area corresponding to the far end of the wiring is insufficiently charged due to signal attenuation and the brightness is low. question. [0003] Therefore, there is a need to provide an organic light-emittin...
