Problems solved by technology
When a still picture is displayed for a long time, the same signal will always be applied to the same pixel. In this case, some impurity ions in the LCD screen will move in a directional manner, forming an additional interference signal, which will cause the vision of the original image to be formed when switching to other screens. Retention, the so-called afterimage, degrades the display quality

Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0029] like image 3 As shown, the pixels in the main liquid crystal screen 1 are divided into left picture pixels and right picture pixels, and the arrangement can be dot intervals or bar intervals (such as Figure 4 ), corresponding to the phase difference liquid crystal screen 2 in front of the main liquid crystal screen 1 are the phase adjustment pixels of the left picture and the phase adjustment pixels of the right picture.
[0030] When displaying odd-numbered frames of pictures, they respectively convert the image information displayed by the pixels of the left picture and the image information displayed by the pixels of the right picture with the same vibration direction and different amplitudes into left phase difference adjusted image information and right phase difference adjusted graphic information, That is, for optical signals with diffe...

Provided is a method for manufacturing a three-dimensional liquid crystal display. When stereo display is achieved by means of a mode that a phase difference liquid crystal display (2) for separating left picture signals and right picture signals and phase difference switch glasses (3) are additionally arranged outside a main liquid crystal display (1), the left picture signals and the right picture signals of left picture pixels and right picture pixels on the main liquid crystal display (1) are alternately switched, and left picture phase adjusting signals and right picture phase adjusting signals of left picture phase adjusting pixels and right picture phase adjusting pixels on the phase difference liquid crystal display (2) are alternately switched correspondingly, so that problems of incidental images and the like caused by the fact that same signals are exerted on a same pixel of the liquid crystal display for a long time can be avoided. Therefore, stereo display quality is improved.
Description
technical field [0001] The invention relates to the field of liquid crystal display manufacture, in particular to a method for eliminating afterimages in a three-dimensional liquid crystal display, in particular to a method for manufacturing a three-dimensional liquid crystal display. [0002] Background technique [0003] At present, traditional CRT monitors rely on cathode ray tubes to emit electrons and strike phosphors on the screen to display images, but the principle of liquid crystal displays is completely different. Generally, a liquid crystal display (LCD) device has an upper substrate and a lower substrate spaced apart from each other and facing each other. A plurality of electrodes formed on the two substrates face each other. The liquid crystal is sandwiched between the upper and lower substrates. A voltage is applied to the liquid crystal through the electrodes on the substrate, and then the alignment of the liquid crystal molecules is changed according to th...
