Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme of exemplary embodiment provided by the present invention is clearly and completely described.
Fig. 1 is the structural representation of liquid crystal display one embodiment of the present invention.As shown in Figure 1, described liquid crystal display 10 comprises backlight 11, light modulation sheet material 12 and display panel 13, light modulation sheet material 12 be positioned at display panel 13 as shown by arrows enter on light direction, backlight 11 can be made up of the multiple light sources be evenly arranged on a sheet material, thus forming surface light source is to guarantee that the light sent evenly enters display panel 13 by light modulation sheet material 12, be arranged in parallel between described sheet material, light modulation sheet material 12 and display panel 13 three.Wherein:
Display panel 13 is traditional display panels, as shown in Figure 2, display panel 13 comprises array base palte (the Thin Film Transistor that parallel interval is arranged, TFT substrate or thin film transistor base plate) 131 and color membrane substrates (Color Filter, CF substrate or colored filter substrate) 132 and the liquid crystal molecule 133 that is held between the two.
Light modulation sheet material 12 is a kind of PDLC (Polymer Dispersed Liquid Crystal, polymer-dispersed liquid crystal) sheet material, as shown in Figure 3, it comprises the first substrate 121 and second substrate 122 and the liquid crystal molecule 123 be held between the two and prepolymer 124 that parallel interval arranges.Light modulation sheet material 12 is actual can show as electronic control type dimming glass plate or liquid crystal light modulation film, when it is electronic control type dimming glass plate, light modulation sheet material 12 can be arranged with display panel 13 parallel interval, and when it is liquid crystal light modulation film, light modulation sheet material 12 can be attached on display panel 13.In embodiments of the present invention, array base palte 131 or the color membrane substrates 132 of display panel 13 is closed on as light modulation sheet material 12, depend on light through which substrate enters, particularly, if light enters display panel 13 and by color membrane substrates 132 outgoing through array base palte 131, then light modulation sheet material 12 closes on array base palte 131 and arranges; If light enters display panel 13 and by array base palte 131 outgoing through color membrane substrates 132, then light modulation sheet material 12 closes on color membrane substrates 132 and arranges.
The preparation method of light modulation sheet material 12 includes but not limited to: first mixed with prepolymer 124 by liquid crystal molecule 123, and be filled into and form liquid crystal cell between the first substrate 121 of box and second substrate 122, then light is used to irradiate the liquid crystal cell being filled with described potpourri, potpourri in liquid crystal cell polymerization reaction take place under the effect of light forms high molecular polymer, wherein high molecular polymer forms spatial skeleton structure under light irradiates, and groove structure is formed between skeleton and skeleton, just polymer dispersion system is defined when liquid crystal molecule 123 moves to groove structure, namely micron-sized liquid crystal molecule 123 is evenly dispersed in macromolecule network.On this basis, utilize the dielectric anisotropy of liquid crystal molecule 123 can control the arrangement mode of liquid crystal molecule 123 in light modulation sheet material 12, thus control the angle of light through light modulation sheet material 12 outgoing.
Backlight 11 can be collimated backlight, namely can only send the light perpendicular to light modulation sheet material 12 and display panel 13, shown in composition graphs 1, described liquid crystal display 10 between narrow visual angle display mode and wide viewing angle display mode, carry out the principle that switches and process as follows:
When exchanging mating plate material 12 and applying voltage, shown in composition graphs 4,
Liquid crystal molecule 123 deflects and passes through to allow described light perpendicular to the first substrate 121 of display panel 13 and second substrate 122, now light modulation sheet material 12 presents transparent outward appearance, be clear state, described light can not to deflect and to be still incident to display panel 13 perpendicular to light modulation sheet material 12 after light modulation sheet material 12 outgoing.When display panel 13 applies gray scale voltage, liquid crystal molecule 133 deflects to allow light to pass through, and the light of outgoing is still perpendicular to display panel 13.Visible, the light that backlight 11 sends does not deflect successively after light modulation sheet material 12 and display panel 13 outgoing, and now only have and just have good view effect along the direction viewing perpendicular to display panel 13, namely liquid crystal display 10 is narrow visual angle display mode.
When not exchanging mating plate material 12 and applying voltage, shown in composition graphs 5,
Liquid crystal molecule 123 does not deflect, and liquid crystal molecule 123 presents irregular distribution, i.e. scattering states, and described light scattering can occur through light modulation sheet material 12, has angle, and be incident to display panel 13 through the light of light modulation sheet material 12 outgoing and light modulation sheet material 12.When display panel 13 applies gray scale voltage, liquid crystal molecule 133 deflects to allow light to pass through, light through display panel 13 outgoing still has angle with display panel 13, now all can have good view effect at multiple directions viewing display panel 13, namely liquid crystal display 10 is wide viewing angle display mode.
When stating principle and process in realization, display panel 13 can be connected power supply separately with light modulation sheet material 12, also same power supply can be connected, namely, for controlling the power supply that the liquid crystal molecule 133 be held between array base palte 131 and color membrane substrates 132 carries out deflecting, also for applying voltage for the liquid crystal molecule 123 be held between first substrate 121 and second substrate 122.
The embodiment of the present invention also provides a kind of novel display panels, that is, above-mentioned light modulation sheet material 12 is integrated into an assembly with traditional display panel 13, and in liquid crystal display.
From the above; the present invention only need increase a light modulation sheet material in entering on light direction of traditional display panel; in order to regulate the angle entering the light of display panel; as long as then select whether to apply voltage to light modulation sheet material; the switching of narrow visual angle display mode and wide viewing angle display mode can be realized; meet the viewing demand of user under different occasion to protect privacy of user with this, the operation carrying out two kinds of display modes switchings is very simple, and cost is lower.
On this basis; the foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize instructions of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; such as the be combineding with each other of technical characteristic between each embodiment; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
