Abstract

The invention discloses a display control method of a liquid crystal display device. The method includes the steps that a first voltage is exerted on a blue sub-pixel B of the center area of a pixel array substrate display region and used for controlling display of the blue sub-pixel B; a second voltage is exerted on a blue sub-pixel B of the peripheral area of the pixel array substrate display region and used for controlling display of the blue sub-pixel B; the peripheral area of the pixel array substrate display region surrounds the center area of the pixel array substrate display region, wherein the second voltage is smaller than the first voltage, so that display brightness of the blue sub-pixel on the peripheral area of the pixel array substrate display region is smaller than that of the blue sub-pixel on the center area of the pixel array substrate display region. Compared with the prior art, the display control method of the liquid crystal display device improves the blue edge problem existing in the periphery of the liquid crystal display device during display, and uniformity of blue light display of the liquid crystal display device is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display control method of a liquid crystal display device. Background technique [0002] A liquid crystal display device cannot emit light independently, therefore, a backlight source needs to be provided in the liquid crystal display device. [0003] The backlight of liquid crystal display devices generally uses blue light-emitting diodes. In a traditional liquid crystal display device, red and green phosphors are usually covered on the blue light-emitting diode, and the red and green phosphors covered on the blue light-emitting diode can convert the blue light emitted by the blue light-emitting diode into white light. [0004] However, this traditional liquid crystal display device has limited performance in improving the color gamut. For example, the color gamut of a traditional liquid crystal display device reaches 100% (NTSC (National Television Standards C...
