A naked-eye 3D display device and manufacturing method thereof

Abstract

The application discloses a naked-eye 3D display device and its manufacturing method, which relates to display technology. The device is provided with a booster layer between the CF ITO layer and the glass substrate, and its position corresponds to the first ITO, and the material of the booster layer is For the transparent material, the thickness of the enhancement layer is less than twice the sum of the thickness of the PVX layer corresponding to the first ITO and the thickness of the second ITO. By setting the increased layer, the distance between the CF ITO layer and the first ITO is reduced, thereby reducing the distance between the CF ITO layer and the first ITO and the distance between the CF ITO layer and the second ITO , thereby reducing the difference in LC deflection, reducing the brightness difference caused by different liquid crystal deflection, and reducing the bright lines existing in the black state.

Description

technical field [0001] The present disclosure generally relates to display technology, specifically to 3D display technology, and in particular to a naked-eye 3D display device and a manufacturing method thereof. Background technique [0002] The emergence of naked-eye 3D mobile phones has greatly attracted the attention of consumers. The basic principle is to add a grating on the basis of ordinary 2D display screens, so that R (for right eye) and L (for left eye) images can be displayed interactively on the LCD panel. If a long and narrow slit (for example, a vertical strip-shaped shading plate) is provided on the liquid crystal panel, the above-mentioned interactively displayed right-eye image will only reach the right eye, and the left-eye image will only reach the left eye, such as figure 1 As shown, the display device includes: a left-eye view 101, a right-eye view 102, a grating opening area 103, and a grating closing area 104, figure 1 A left eye 105 and a right eye ...

AI Technical Summary

Problems solved by technology

[0006] However, the inventors of the present invention have found that the liquid crystal grating of this type of structure more or less has the problem of bright lines. This is because although the voltages given by the first ITO and the second ITO are the same, the electric field of the TN type is a vertical electric field. Its rated voltage is related to the distance between TFT and ITO of CF, therefore, in such as figure 2 In the structure shown, when the first ITO and the second ITO are given the same voltage, due to the existence of the PVX layer, D≠d, so that the VOP is different, resulting in differences in the corresponding LC deflection, and the liquid crystal deflection is different Causes its brightness to be different, thus causing the presence of bright lines in the black state
