Problems solved by technology

[0003] In the process of realizing the above-mentioned 3D display solution, the inventors found that there are at least the following problems in the prior art: when a parallax barrier with a fixed pattern is used, after the parallax barrier is set on the display panel, the display panel can only perform 3D display and cannot Then switch to 2D (two-dimensional) display; when using LCD to make a parallax barrier, although it can be converted to 2D display by controlling the light transmission of liquid crystal, it is required that the light source used in the display panel display is polarized light. As far as the display panel of the ordinary light source of light is concerned, it cannot be converted to 2D display

Embodiment 1

[0033] An embodiment of the present invention provides a parallax barrier, which specifically includes a transparent barrier, on which at least one group of patterns switching between a light-absorbing state and a light-transmitting state is provided, and each group of patterns is in a light-absorbing state , a slit grating for naked-eye three-dimensional display can be formed on the transparent baffle. Specific as figure 2 and image 3 As shown, the transparent baffle in the embodiment of the present invention includes two layers of overlapping transparent substrates 21 and 22, and a transparent liquid 23 filled between the two layers of transparent substrates 21 and 22; the above two layers of transparent substrates can be used The sealing glue is combined to ensure that the filled transparent liquid will not seep out, and the thickness of the box can be controlled by a spacer between the transparent substrates after the combination. In order to form a slit grating for na...

Embodiment 2

[0056] An embodiment of the present invention provides a display panel, such as Figure 8 and Figure 9 As shown, a display unit is included, and at least one parallax barrier is provided on the display surface of the display unit. For the specific structure of the parallax barrier, reference may be made to the above-mentioned embodiment 1, which will not be repeated here.

[0057] When the display surface of the display unit is provided with a parallax barrier, generally there is only one best observation point. In order to have multiple best viewing points, the embodiment of the present invention can use a parallax barrier with multiple sets of patterned electrodes, and by switching between these patterned electrodes, the display panel has multiple best viewing points . For example: when the parallax barrier realizes the light-absorbing state of the corresponding area of ​​the first type of patterned electrode, it is the first type of slit grating, and correspondingly has ...

Embodiment 3

[0073] An embodiment of the present invention provides a method for preparing a parallax barrier, the method comprising:

[0074] Step 1, forming transparent electrodes on two transparent substrates, wherein the transparent electrodes on one transparent substrate include a set of patterned electrodes or at least two sets of patterned electrodes that can be energized separately;

[0075] Step 2: combine the two transparent substrates formed with transparent electrodes, and fill the space between the two combined transparent substrates with a transparent liquid. The transparent liquid in the region corresponding to the patterned electrode in the energized state becomes opaque, forming a light-absorbing state pattern with the same shape as the patterned electrode in the energized state.

[0076] In the embodiment of the present invention, the upper and lower layers of transparent substrates can be relatively formed into an empty cell (Cell) with the sealing glue, and the height o...

Abstract

The invention discloses a parallax baffle plate, a display panel and a preparation method of the parallax baffle plate, relates to the technical field of display and aims at solving the problem that conversion between 2D (two-dimensional) display and 3D (three-dimensional) display can not be realized through a traditional parallax baffle plate method under the situation of using an ordinary non-polarized light source. The invention can be simultaneously applied to a polarized light source. The parallax baffle plate disclosed by the embodiment of the invention comprises a transparent baffle plate, at least one group of patterns switching between a light absorption state and a light transmission state are arranged on the transparent baffle plate, and when each group of the patterns are in the light absorption state, a slit grating for naked-eye three-dimensional display is formed on the transparent baffle plate. The embodiment of the invention is mainly used for the parallax baffle plates and the display panels, in particular to the display panels with the need of switching the display between 3D and 2D.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a parallax barrier in the display technology, a display panel and a preparation method of the parallax barrier. Background technique [0002] In the existing 3D (three-dimensional) display technology, a parallax barrier 12 is generally provided on one side of the display screen of the display panel 11 . Specific principles such as figure 1 As shown, a slit grating is arranged on the parallax barrier, and the images of the pixels on the display panel 11 propagate to the observation point through the slits on the parallax barrier 12, from figure 1 It can be seen from the figure that the pixels of the display panel that can be observed by the left eye 13 and the right eye 14 at the observation point are different, so that the observer can observe two different images at the observation point, forming a 3D display. Existing parallax baffles are generally made with fixed patterns, ...
