Embodiment
In the following description, give a large amount of concrete details to provide to understand more thoroughly the utility model.But, it is obvious to the skilled person that the utility model can be implemented without the need to these details one or more.In other example, in order to avoid obscuring with the utility model, technical characteristics more well known in the art are not described.
In order to thoroughly understand the utility model, by proposing detailed step and detailed structure in following description, to explain the technical solution of the utility model.Preferred embodiment of the present utility model is described in detail as follows, but except these are described in detail, the utility model can also have other embodiments.
Fig. 1 shows the sectional view of a kind of liquid crystal display in prior art, comprises backlight 200, LCDs 100.If need to adopt the display device of this structure to show, general needs cuts, and concrete defect is existing relevant record in background technology above, does not repeat them here.
According to the many disadvantages of liquid crystal display device in prior art, the utility model provides a kind of liquid crystal indicator, with reference to shown in Fig. 2 and Fig. 3, this liquid crystal indicator mainly comprises: backlight 202 and the display screen 203 be arranged on backlight 202, between backlight 202 and display screen 203, or be provided with PDLC thin layer 300 on display screen 203.Simultaneously, shown in Fig. 4, PDLC thin layer 300 comprises upper substrate 305 and infrabasal plate 301, between upper substrate 305 and infrabasal plate 301, be provided with polymerised liquid crystal layer 303, at upper substrate 305, between infrabasal plate 301 and polymerised liquid crystal layer 303, be provided with the electrode layer that has electrode pattern.Also between upper substrate 305 and polymerised liquid crystal layer 303, the second electrode lay 304 that one has electrode pattern is namely provided with, same, between infrabasal plate 301 and polymerised liquid crystal layer 303, be provided with the first electrode layer 302 that has electrode pattern.The utility model is by carrying out independent control to the electrode layer of polymerised liquid crystal layer about 303 both sides respectively, the refractive index of polymerised liquid crystal layer 303 is controlled by the electric field be carried between the first electrode layer 302 and the second electrode lay 304, thus realize switching between clear state and opaque state, realize switching function, and with the change of on-load voltage, transmitance can present roll-off characteristic, namely also possesses gray scale regulatory function.
Its type of drive is as shown in Fig. 8 a and Fig. 8 b, Fig. 9 a and Fig. 9 b.Constant common electric voltage (such as 0V) is added at the first electrode layer 302.The second electrode lay 304 adds the square wave (maximal value+V, minimum value-V volt) that peak value is 2V volt, and voltage V can choose as required between 0-100V, and the driving voltage required for different polymer liquid crystal material is different.Its principle of work is when without impressed voltage, and namely as figures 8 a and 8 b show, the first electrode and the second electrode are all constant common electric voltage (such as 0V), do not have voltage difference between two electrodes.Regular electric field can not be formed in PDLC thin layer, the direction of optic axis of liquid crystal particle is random, in disordered state, its effective refractive index (no) does not mate with the refractive index (np) of polymkeric substance, therefore incident ray is by strong scattering, film is opaque or translucent, and we are referred to as PDLC closed condition, or is black state.And as shown in figures 9 a and 9b, after being applied with external voltage, namely the first electrode adds constant common electric voltage (such as 0V), second electrode adds the square wave (maximal value+V that peak value is 2V volt, minimum value-V volt), voltage V can choose as required between 0-100V, and the optical axis of liquid crystal particle arranges perpendicular to film surface, namely consistent with direction of an electric field.The refractive index no of liquid crystal particle mates substantially with the refractive index of polymkeric substance, and without sharp interface, approximate formation uniform dielectric, so incident light scattering does not occur, the transparent shape of film, we are referred to as PDLC open mode, or are on state of.So just can be reached through and control the voltage that is added between PDLC upper/lower electrode to regulate scattering degree, the brightness of transmitted light, realize the object that switch and GTG control.Simultaneously because the first electrode layer 302 and the second electrode lay 304 are for having the electrode layer of electrode pattern, each layer electrode layer is controlled respectively by driving circuit, can realize showing complex pattern, do not need to carry out too large change to available liquid crystal module, simple for process, the method that attainable viewing area is versatile and flexible and dynamically controlled.Simple and effectively can realize viewing area adjustable flexibly, for the irregular display application of liquid crystal display module opens new way.
