The present disclosure provides a display driving device, method and an OLED display device, and the display driving device includes: an interface module, configured to receive image data of a display chip and sending a first scanning signal in each of frame periods; a frame buffer, configured to send a buffer signal after receiving the first scanning signal from the interface module; a timing controller, configured to send a second scanning signal to the display panel according to the buffer signal sent by the frame buffer; in response to the display driving device is switched from a screen self-refresh mode to a vertical synchronization mode, the delay time between the second scanning signal and the buffer signal gradually decreases, one frame period by one frame period, to zero or gradually increases, one frame period by one frame period, to duration of one frame period. When the display device is switched back to the vertical synchronization mode, the present disclosure causes the vertical synchronization signal generated by the display chip and the timing controller to be resynchronized for reducing phase mismatch, thereby improving display response speed of the display device.

Display driving device, method and OLED display device

The present disclosure provides a blue light organic light-emitting diode, which includes a first electrode layer; a first hole injection layer disposed on the first electrode layer; a second hole injection layer disposed on first hole injection layer; a hole transport layer disposed on the second hole injection layer; a blue light emitting material layer disposed on the hole transport layer; an electron transport layer disposed on the blue light emitting material layer; and a second electrode layer disposed on the electron transport layer, wherein the second hole injection layer has a thickness of 85 nm&#x2dc;105 nm. The present disclosure further provides a display including the device. The blue light organic light-emitting diode of the present disclosure can control blue light energy components having a wavelength less than 435 nm within 0.2%, which reduces the harm of the blue light in the wave band to human eyes to a great extent.
