[0003] However, in order to accurately project the content displayed by different pixels into the left and right eyes of people, the micro-cylindrical lens in the 3D lens and the pixels of the flat panel display need to be very accurately aligned. At present, generally by setting the 3D lens and the flat panel display However, due to the deviation between the alignment mark and the pixel and the 3D lens, this method cannot directly reflect the final 3D effect, resulting in the distance between the central axis of the stereoscopic display and the left and right eyes. It is difficult to align the central axis accurately, and its 3D images often cannot be accurately projected into the left and right eyes of the user, and the 3D visual effect is poor.

An alignment and lamination method of a 3D lens and a flat-panel display provided by the invention comprises the following steps: driving the flat-panel display to generate mixture of colors images which include a first color corresponding to a left viewing angle pixel and a second color corresponding to a right viewing angle pixel, projecting the mixture of colors images on a projection screen via the 3D lens, observing the mixture of colors images on the projection screen while regulating the relative location of the 3D lens and the flat-panel display leftwards and rightwards until the two colors of the mixture of colors images on the projection screen are clearly separated, and then driving the 3D lens to gradually approach to the flat-panel display until laminating the flat-panel display. The mixture of colors images on the flat-panel display are directly projected through the 3D lens, and the relative location of the 3D lens and the flat-panel display is regulated leftwards and rightwards, when the boundary of the two colors of the mixture of colors images on the projection screen is accurately aligned, left and right 3D images may be accurately projected into users' left and right eyes so as to improve 3D visual effect.
Description
technical field [0001] The invention relates to a manufacturing method of a display, in particular to a method for aligning and bonding a 3D lens and a flat panel display and a device for aligning and bonding. Background technique [0002] In order to realize a stereoscopic display with a naked-eye 3D function, 3D lenses (including electrically controlled liquid crystal lenses or general lenticular lenses) are often arranged in front of a flat panel display. The 3D lens generally includes a plurality of side-by-side micro-cylindrical lenses. When the distance between the flat-panel display and the 3D lens is set, different pixels (which can be divided into left pixels and right pixels) corresponding to different positions of the micro-cylindrical lenses in the flat-panel display can be respectively Projected in different directions, the content displayed by different pixels can enter the left and right eyes respectively to achieve 3D vision. [0003] However, in order to ac...
