Method for guaranteeing color consistency of display image quality, liquid crystal display panel and display

Abstract

The invention provides a method for guaranteeing color consistency of display image quality. The method comprises the steps as follows: step 1, trial-producing a backlight sample by a white light emitting diode with chromaticity Bin, matching a standard LCD (liquid crystal display) optical element, measuring an optical parameter, and calculating a chromaticity offset relationship after the white light emitting diode with chromaticity Bin is matched with the LCD optical element; step 2, selectively dividing a chromaticity Bin region of the white light emitting diode into more than two different color ranges; step 3, respectively applying the white light emitting diode with the different color ranges in the step 2 to a backlight source of a backlight system of the LCD with the corresponding size; step 4, trail-producing a color filter, and correcting a light transmission parameter of an R\G\B (red\green\blue) unit of the color filter of the LCD optical element; and step 5, taking the corrected color filter of the LCD optical element as a standard, and matching with the matched backlight source in the step 3 to form a finished product. The color consistency of the display image quality of the LCD can be guaranteed, therefore the image quality is improved.

Description

technical field [0001] The invention relates to the field of displays, in particular to a method for ensuring color consistency of display quality, a liquid crystal display panel and a display. Background technique [0002] As the popularity of liquid crystal products continues to increase, people's requirements for liquid crystal displays are also getting higher and higher. The quality of the LCD screen determines the quality of the LCD, and the quality of the LCD screen is determined by the LCD panel. The liquid crystal display panel (LCD Panel) in the liquid crystal display is composed of a backlight system (B / L) that provides brightness and an LCD optical element (LCD CELL) that controls the picture; and the color rendering of the LCD panel (LCD Panel) is determined by the backlight The spectrum of the white light-emitting diode (WLED) in the system (B / L) is determined by the color filter (RGB Color Filter) in the LCD optical element (LCD CELL); [0003] Due to the dev...

Problems solved by technology

In industrial production, the color temperature of each display can be calibrated, and its chromaticity value can be measured with a precision optical instrument (such as Chroma CA210). The allowable deviation range of chromaticity in the prior art is: Δ(x,y)= (0.313,329)+ / -0.030, this range cannot guarantee the consistency of display quality and color, the current method to improve this offset range is to reduce the application range of WLED chromaticity Bin: but this will reduce the utilization rate of WLED raw materials, increase production costs
