The spliced display device comprises at least one first display panel and at least one second display panel. An end of first display is backwardly bended away display surface at boundary between display region and non-display region. An end of second display panel is adjacent to first display panel and end of second display panel facing and correspondingly fixed to non-display region of first display panel after been bended. The spliced display device provides at least one non-display region is bended and stitched to other display panel.

Abstract: A driving control method is disclosed. The method includes steps of sequentially turning on the first color sub-pixel, the second color sub-pixel, the third color sub-pixel and the white color sub-pixel respectively in the first time period, the second time period, the third time period, and the fourth time period in order to respectively input grayscale values of the sub-pixels using the source driver. Wherein, when using the source driver to input the grayscale vale of the white color sub-pixels, the source driver decreases a preset value of gamma voltages of the white color sub-pixels such that the preset value of gamma voltages when inputting grayscale values of the white color sub-pixels is less than a preset value of gamma voltages when inputting grayscale values of the first color sub-pixels, the second color sub-pixels and/or the third color sub-pixels. Through the above way, the display quality can be increased.

Abstract: The present invention provides a backlight module comprising a LED backlight source. The LED backlight source comprises at least two LED light source sets disposed alternatively; each LED light source set comprises red LED lights, green LED lights and blue LED lights arranged in array formation; and a color gamut of the red and green LED lights in two neighbored LED light source sets are different. The present invention further provides a control method of display device. The LED backlight source is controlled and a corresponded RGB grey level is output to the display device according to the percentage of the areas of the red and green pixels having color saturation value greater than the color saturation threshold. Comparing to the existed technology, uncomfortableness on watching red pixels and green pixels is reduced and comfort of human eyes while watching images with high color gamut is improved.
