The motion blur of a large-size, organic, light-emitting device (OLED) panel could be reduced by decreasing the moving-picture response time (MPRT). The MPRT of an OLED display panel with a fast response was significantly affected by the frame frequency and the compensation driving method, and the MPRTs of large-size OLED display panels could be significantly decreased by using an integrated gate driver circuit with a MPRT reduction method. The MPRT was decreased due to the ability to turn the emitting pixels off in advance, which was possible due to the provision of black data. The integrated gate drivers were designed so that a normal display, black data insertion, and operation in the compensation mode could be achieved. The MPRT of a 65-inch ultra-high-definition (UHD) OLED panel was decreased to 3.4 ms by using an integrated gate driver circuit. The MPRT reduction method proposed in this study can reduce the MPRT time to below 6.8 ms according to the black data insertion duty. This MPRT time of 6.8 ms can be further reduced to 3.4 ms in 50% black data duty, showing a 50% MPRT improvement. Thus, the motion blur of such large-size OLED display panels can be significantly reduced by decreasing the value of the MPRT.

由于采用动态图像响应时间缩短方法的集成栅极驱动器电路,减少了大尺寸有机发光设备面板中的运动模糊

可以通过减少动态图像响应时间 (MPRT) 来减少大尺寸有机发光器件 (OLED) 面板的运动模糊。具有快速响应的OLED显示面板的MPRT受帧频和补偿驱动方式的影响显着,使用MPRT降低方法的集成栅极驱动电路可以显着降低大尺寸OLED显示面板的MPRT . 由于提供了黑色数据,可以提前关闭发光像素,因此 MPRT 降低。集成栅极驱动器的设计使得可以实现正常显示、黑色数据插入和补偿模式下的操作。65英寸超高清(UHD)OLED面板的MPRT降至3。4 ms 通过使用集成栅极驱动器电路。本研究提出的 MPRT 缩减方法可以根据黑数据插入任务将 MPRT 时间降低到 6.8 ms 以下。在 50% 的黑色数据占空比下,这个 6.8 ms 的 MPRT 时间可以进一步减少到 3.4 ms,显示出 50% 的 MPRT 改进。因此,可以通过降低MPRT的值来显着降低这种大尺寸OLED显示面板的运动模糊。
