Abstract: A compensation circuit and an Organic Light Emitting Diode (OLED) device are disclosed. The compensation circuit includes a driver switch for driving a load, a reset energy storage element coupled to a to-be-reset terminal of the driver switch; and a reset charging circuit coupled to the reset energy storage element. During when the driver switch is reset, the reset charging circuit sequentially outputs a fast charging signal and a reset initialization signal to the reset energy storage element; the fast charging signal is for fast charging the reset energy storage element. The reset initialization signal is for adjusting the voltage output from the reset energy storage element to the driver switch's to-be-reset terminal to a preset voltage. Through the above design, the reset energy storage element may be fast charged with reduced charging time during the Reset stage, enhancing the Reset efficiency.

Abstract: Disclosed is a method for alleviating color shift of a display panel at a large viewing angle. The panel includes a sub-pixel array formed by R, G, B sub-pixels, and black matrix areas located between the sub-pixels. The method includes providing, above the sub-pixel array, an optical grating that is parallel with the sub-pixel array. The optical grating includes transparent areas and non-transparent areas. The non-transparent areas are provided above the black matrix areas. The optical grating is configured as such that when a sub-pixel is observed at a large viewing angle, light transmitted through the sub-pixel is partially blocked by the non-transparent areas of the optical grating.
