As shown in Figure 1, the invention proposes a kind of test methods for display module, comprising:
Step S100 obtains the limiting value of chromaticity coordinates and the limiting value of brightness in display module by processing module 100.
In this present embodiment, display module can be in display, smart television, PC or other display equipment Display module etc., the present invention is not limited thereto.The basic hardware environment of the display module at least include display panel with And backlight module, above-mentioned display panel are preferably liquid crystal display panel, and backlight module then include LED light, PCB circuit board and Drive the components such as IC.In addition, the display module logically further includes having the moulds such as pattern acquiring, colour temperature are searched and colour temperature adjusts Block.
Before step S100, tester can obtain the reality that multiple groups include chromaticity coordinates and brightness in defaulting under color temperature levels Actual value, and the limiting value of chromaticity coordinates and the limiting value of brightness are obtained according to multiple groups actual value.For example, manufacturer is in 6500K's The chromaticity coordinates of the display module and brightness are measured under color temperature levels, thus obtain 30 groups include chromaticity coordinates and brightness reality Actual value, then above-mentioned numerical value is counted further by statistical estimations methods such as Six Sigma (6Sigma), by above-mentioned six west Lattice Ma statistical method analytic operation show that the value range of the abscissa (X) of chromaticity coordinates is 0.311 ± 0.015, ordinate (Y) Value range is 0.33 ± 0.013, and the value range of brightness is 253 ± 27nits.It should be noted that above-mentioned chromaticity coordinates and The example value that the specific value of brightness is actually obtained in operating process, is used only as the explanation illustrated in order to embodiment herein.
Thus, the limiting value of the chromaticity coordinates of display module includes the upper limit value X of abscissamax, lower limit value Xmin, ordinate Upper limit value Xmax, lower limit value Xmin, and the limiting value of brightness then includes upper limit value LmaxAnd lower limit value Lmin
Then, display module can be by the processing modules such as central processing unit 100 to the limiting value and brightness of above-mentioned chromaticity coordinates Limiting value handled, specifically, processing module 100 can be by the upper of the upper limit value of abscissa and lower limit value and ordinate Combination of two between limit value and lower limit value, to form the value for being applied to the chromaticity coordinates of display picture.For example, chromaticity coordinates takes Value can be (Xmin=0.296, Ymin=0.317), (Xmin=0.296, Ymax=0.343), (Xmax=0.326, Ymin= 0.317)、(Xmax=0.326, Ymax=0.343);And since user is usually to display module under specific circumstances minimum bright Degree there are certain requirements, therefore in this present embodiment, the lower limit value of the brightness, such as above-described embodiment are preferably chosen to the value of brightness It is previously mentioned, Lmin=226nits.
