Abstract: The present invention provides a blue light compensation film and an OLED display. The blue light compensation film of the present invention effectively absorbs blue light with wavelength longer than blue wavelength and excite blue light by using a blue light upconversion luminescent material, and effectively improves color shift white OLED device caused by short lifespan of blue electroluminescent material to achieve blue light compensation of the white OLED device and solve the of yellowing in traditional OLED display with age. The OLED display of the present invention comprises the blue light compensation film to avoid color shift problem and provides good display quality.

Abstract: An array substrate and a display panel are provided. Pixel units of the array substrate include a thin film transistor region, pixel electrode regions, thin film transistors disposed in the thin film transistor region, and pixel electrodes disposed in the pixel electrode regions. The pixel electrode is electrically connected to the thin film transistor. Meanwhile, a shielding member is further disposed in the thin film transistor region, and an interval between the shielding member and the pixel electrode in an extending direction of data lines is a first threshold value.
