The invention provides a method and device for detecting the surface topography of a color film. The device comprises a power source and a light ray detector which are arranged oppositely, a first guide rail, a base capable of moving along the first guide rail, and a second guide rail fixed on the base and whose extending direction is parallel to the first guide rail. The light ray detector is connected with the second guide rail and can move along the extending direction of the second guide rail. The first guide rail is provided with multiple first fixing points which are used for enabling the second guide rail arranged on the base to align to each monochrome sub pixel arranged on a color film base plate. The second guide rail is provided with multiple second fixing points which are used for enabling the light ray detector to align to multiple location points of each monochrome sub pixel arranged on the color film base plate. The method and device for detecting the surface topography of the color film can realize simultaneous measurement of the chromatic value and the surface topography information of the monochrome sub pixel.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a method and device for detecting the surface topography of a color filter. Background technique [0002] In the prior art, a spectrophotometer can be used to detect the chromaticity value of a single-color sub-pixel. Such as figure 1 As shown, the spectrophotometer includes a white point light source, a light source module for controlling the light emission and movement of the white point light source, a probe, and a spectrometer connected to the probe. The point light source is placed on one side of the monochrome sub-pixel, and the light passing through the monochrome sub-pixel is received by the probe on the other side, so as to obtain the transmission spectrum of the monochrome sub-pixel, which can be calculated according to the data in the transmission spectrum The chrominance value corresponding to each monochrome sub-pixel is obtained. [0003] However, in the prior a...
