ORGANIC LIGHT-EMITTING DISPLAY DEVICE |
摘要 |
An organic light-emitting display device which divides each frame into a plurality of sub-frames and represents gray levels based on the sum of the lengths of one or more sub-frames during which light is emitted, the organic light-emitting display device comprising a display unit including a plurality of pixels arranged in a matrix, a scan driver configured to provide a scan signal to the display unit during each sub-frame period and a precharge voltage unit configured to provide a precharge voltage to the pixels, wherein the pixels are divided into a first pixel column block including a pixel receiving the scan signal before the other pixels and a second pixel column block next to the first pixel column block in a direction of the application of the scan signal and the precharge voltage is selectively provided to pixels included in the first pixel column block. |

1. An organic light-emitting display device which divides each frame into a plurality of sub-frames and represents gray levels based on a sum of lengths of one or more of the plurality of sub-frames during which light is emitted, the organic light-emitting display device comprising:
a display unit comprising a plurality of pixels arranged in a matrix; a scan driver configured to provide a scan signal to the display unit during each sub-frame period; and a precharge voltage unit configured to provide a precharge voltage to the pixels, wherein the pixels are divided into a first pixel column block comprising a pixel configured to receive the scan signal before other pixels receive the scan signal, and a second pixel column block next to the first pixel column block in a direction of an application of the scan signal, and the precharge voltage is selectively provided to pixels in the first pixel column block. |
