Embodiment
Below in conjunction with accompanying drawing the utility model liquid crystal display module and plane/stereo switchable liquid crystal display device are described.
See also Fig. 1, Fig. 1 is the structural representation of the utility model plane/stereo switchable liquid crystal display device.This plane/stereo switchable liquid crystal display device comprises backlight 1, LCD 2 and is located at the liquid crystal grating module 3 of these LCD 2 one side surfaces.
This liquid crystal grating module 3 comprises first glass substrate 10, first transparent electrode layer 20, first alignment film 30, second alignment film 40, second transparent electrode layer 50, second glass substrate 60, polaroid 70, liquid crystal layer 80 and frame 90.
This first transparent electrode layer 20 is formed at this first glass substrate, 10 contiguous these second glass substrate, 60 1 side surfaces, and this first alignment film 30 is formed at this first transparent electrode layer 20.This second transparent electrode layer 50 is formed at this second glass substrate, 60 contiguous these first glass substrate, 20 1 side surfaces, and this second alignment film 40 is formed at this second transparent electrode layer 50.This frame 90 and surrounds an enclosure space with this first alignment film 30 and this second alignment film 40 between this first transparent electrode layer 20 and this second transparent electrode layer 50, these liquid crystal layer 80 sealings are contained in this enclosure space.
See also Fig. 2, Fig. 2 is formed in the structural representation of this first transparent electrode layer 20 on these first glass substrate, 10 surfaces.This first transparent electrode layer 20 is for being printed to whole transparency electrode figure, and it externally electrically connects by electrode pin (not indicating).In other embodiments, this first transparent electrode layer 20 can also be designed to strip transparency electrode figure at interval, as shown in Figure 3.
See also Fig. 4, Fig. 4 is formed in the structural representation of this second transparent electrode layer 50 on these second glass substrate, 60 surfaces.This second transparent electrode layer 50 comprises a plurality of vertical electrode strips, and this vertical electrode strip is respectively to sub-pixel setting that should LCD 2.These a plurality of vertical electrode strip periodic intervals distribute, and it comprises two kinds of different width along the pixel orientation perpendicular to this LCD 2, and this a plurality of vertical electrode strips edge is identical perpendicular to the width in the pixel orientation slit of this LCD 2.That is to say that when the RGB vitta of the liquid crystal panel of this LCD 2 is when vertically arranging, these a plurality of vertical electrode strip along continuous straight runs have two kinds of different width, and the spacing between the adjacent vertical electrode strip is identical.With Fig. 4 is example, per three vertical electrode strips form a vertical electrode strip group among Fig. 4, the width in slit is identical between same group of vertical electrode strip, this is organized vertical electrode strip and comprises the vertical electrode strip of two first width and the vertical electrode strip of one second width, wherein, this second width is greater than this first width.That is to say that this liquid crystal grating module 3 is non-homogeneous liquid crystal grating module.Applying under the driving voltage state, the lightproof area and the transmission region of the formation periodic intervals distribution that this liquid crystal grating module 3 can be corresponding, this lightproof area and this transmission region all are vertical arrangements.The width of this transmission region of slit correspondence equates between this vertical electrode strip, and this lightproof area of this vertical electrode strip correspondence comprises at least two kinds of different width.
The material of this first transparent electrode layer 20 and this second transparent electrode layer 50 can be tin indium oxide (ITO) or indium zinc oxide (IZO).
During this plane/stereo switchable liquid crystal display device work, when needs carry out stereo display, this first transparent electrode layer 20 and this second transparent electrode layer 50 are applied driving voltage, and the light of this LCD 2 appears by this liquid crystal grating module 3, forms parallax.Seeing also Fig. 5, is that this liquid crystal grating module 3 is at the show state that applies under the driving voltage.For being described, this plane/stereo switchable liquid crystal display device of the present utility model can well avoid showing the problem of colour cast, with Fig. 6 and Fig. 7 is the example contrast, Fig. 6 is an occlusion effect synoptic diagram of using this plane/stereo switchable liquid crystal display device of this liquid crystal grating module 3, and Fig. 7 is the occlusion effect synoptic diagram of conventional occluded pixels mode.As can be seen, compare with conventional occluded pixels mode, this plane/stereo switchable liquid crystal display device of the present utility model can avoid showing the problem of colour cast really, and does not need the display panels and the controllable liquid crystal grating of the higher slimming of cost, so its cost is lower.
When this plane/stereo switchable liquid crystal display device only needs to carry out the plane demonstration, can cancel driving voltage to this first transparent electrode layer 20 and second transparent electrode layer 50, then this liquid crystal grating module 3 presents pellucidity, the light of this LCD 2 can not form parallax by this liquid crystal grating module, and this moment, this plane/stereo switchable liquid crystal display device promptly can present the plane demonstration.
To sum up, this liquid crystal grating module 3 of the present utility model and the plane/stereo switchable liquid crystal display device of using this liquid crystal grating module 3 have the advantage that cost is lower, can avoid taking place colour cast.
Only be preferred case study on implementation of the present utility model below, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
