Embodiment Construction

[0036] An embodiment of the present invention provides an image display device, which includes: a backlight module and a plurality of liquid crystal cells; wherein, any two of the liquid crystal cells in the plurality of liquid crystal cells have overlapping areas on their orthographic projection surfaces; the The light incident surfaces of the plurality of liquid crystal cells are set opposite to the light output surface of the backlight module. According to the structure of the display panel to be tested, the embodiment of the present invention selects the corresponding liquid crystal cell, so that the combination of multiple liquid crystal cells and the backlight module simulates the structure of the display panel to be tested, so that an image can be formed by the device of the embodiment of the present invention. Observe whether there is moiré, so that in the product design stage, it is possible to detect whether the display panel can produce moiré, thereby reducing the pr...

Abstract

The invention discloses an image display device and method. The device comprises a backlight module and a plurality of liquid crystal boxes. The front projections of any two of the liquid crystal boxes have overlaid regions. Light incident faces of the liquid crystal boxes and light emitting faces of the backlight modules are oppositely arranged. According to the image display device and method, on the basis of the structure of a display panel needing to be tested, the corresponding liquid crystal box is selected, the liquid crystal boxes and the backlight module are assembled to simulate the structure of the display panel needing to be tested, and therefore images can be formed through the image display device and method, whether moire is generated or not is observed, whether moire can be generated or not on the display panel or not can be detected in the product designing stage, and the moire generation probability is decreased.

Description

technical field [0001] The present invention relates to the field of display panels, in particular to an image display device and method. Background technique [0002] In a narrow sense, the beating principle refers to the superposition of two equal-amplitude sine waves with close frequencies, and the frequency of the synthesized signal will change according to the difference between the two frequencies. At the same time, the beating principle is also applicable in terms of spatial frequency. When fringes with slightly different spatial frequencies are superimposed, the fringe intervals and overlapping positions will gradually shift, thereby forming beats. [0003] Among them, moiré is a manifestation of the beat principle. For the field of display panels, the interference between the BLU (Back Light Unit, backlight module) prism sheet and the pixel structure, and the OGS pattern (One Glass Solution Pattern, single-chip touch panel pattern) are the causes of moiré. , the ...
