Detailed description of the invention
The present invention is described in detail with embodiment below in conjunction with the accompanying drawings.
It is the structural representation of display panels according to embodiments of the present invention referring firstly to Fig. 1, Fig. 1.Such as Fig. 1 institute
Showing, the present invention provides a kind of display panels, including: color membrane substrates 102, sealing 106, TFT (Thin Film
Transistor, thin film transistor (TFT)) substrate 104, liquid crystal layer 103, upper polaroid 101, lower polaroid 105 and driving chip
108。
Wherein, TFT substrate 104 is oppositely arranged with color membrane substrates 102, and (figure is not to be provided with public electrode in TFT substrate 104
Show, hereafter can be discussed in detail), liquid crystal layer 103 is arranged between color membrane substrates 102 and TFT substrate 104, and upper polaroid 101 adulterates
Having conducting particles, be arranged on the color membrane substrates 102 surface away from liquid crystal layer 103, upper polaroid 101 is relative with public electrode,
Lower polaroid 105 is arranged on the TFT substrate 104 surface away from liquid crystal layer 103, and sealing 106 arranges color membrane substrates 102 and TFT
Between substrate.Driving chip 108 is arranged in TFT substrate 104, electrically connects with upper polaroid 101, is used for controlling upper polaroid
101 energisings.
Owing to upper polaroid 101 is doped with conducting particles, therefore going up polaroid 101 after powered up can be relative to public electrode
Produce electric field.
And continuing with seeing Fig. 1, as shown in Figure 1, TFT substrate 104 preferably can be by a silver-colored sizing process and upper polarisation
Sheet 101 electrically connects, specifically, the side of upper polaroid 101 by a silver-colored slurry mode via the side of color membrane substrates 102, liquid
The side of crystal layer 103 electrically connects with TFT substrate 104, so that the driving chip 108 being arranged in TFT substrate 104 can be with upper
Polaroid 101 electrically connects.
It should be noted that selecting the silver-colored sizing process only present invention realizes being electrically connected between TFT substrate 104 and upper polaroid 101
A kind of preferred implementation connect, it has the simple advantage of processing procedure, and in other alternative embodiments of the present invention, also
The electrical connection between TFT substrate 104 and upper polaroid 101 can be realized in the way of using wire jumper or flexible PCB.
And to refer to Fig. 2, Fig. 2 be that display panels according to embodiments of the present invention is after upper polaroid 101 is energized
Structural representation, wherein, when needs enter narrow visual display pattern, driving chip 108 exports the first pre-voltage to TFT substrate
The source electrode 1041 of 104, so that the first electric field formed between source electrode and public electrode makes the liquid crystal of liquid crystal layer 103
Deflect, and export the second supreme polaroid of predetermined voltage 101, so that between upper polaroid 101 and public electrode 1042
Forming the second electric field makes the liquid crystal deflected up tilt predetermined angular, thus realizes narrow visual display.
Wherein, it is equal that the first predetermined voltage and the second predetermined voltage are preferably magnitude of voltage, so that driving chip 108 nothing
Transformation need to be carried out, it is only necessary to same voltage is inputted respectively source electrode 1041 and upper polaroid 101.
Wherein, when needs enter wide visual display pattern, driving chip 108 exports the first pre-voltage to TFT substrate 104
Source electrode, and stop exporting the second supreme polaroid of predetermined voltage 101, so that shape between source electrode and public electrode
The first electric field become makes the liquid crystal of liquid crystal layer 103 deflect.
In order to make it easy to understand, be please that display panels according to embodiments of the present invention is being executed with further reference to Fig. 3, Fig. 3
The view of liquid crystal after added electric field.As it is shown on figure 3, when display panels does not works and shows blank screen, driving chip
108 stop output the first pre-voltages to the source electrode 1041 of TFT substrate 104, and it is supreme partially to stop exporting the second predetermined voltage
Mating plate 101, so that liquid crystal molecule maintains non-deflected state, now, is positioned at the backlight below TFT substrate 104 and produces
Light can not pass through display panels, therefore display panels presents black state.
When display panels needs to enter wide visual display pattern, driving chip 108 exports the first pre-voltage to TFT
The source electrode 1041 of substrate 104, and stop exporting the second supreme polaroid of predetermined voltage 101, so that source electrode 1041
And the first electric field formed between public electrode 1042 makes the liquid crystal of liquid crystal layer 103 deflect.Now, the light that backlight produces
Line can pass through display panels, and is projected to eyes of user, thus realizes wide visual display.
When display panels enters narrow visual display pattern at needs, driving chip 108 exports the first pre-voltage extremely
The source electrode 1041 of TFT substrate 104, so that the first electric field order formed between source electrode 1041 and public electrode 1042
The liquid crystal of liquid crystal layer 103 deflects, and exports the second supreme polaroid of predetermined voltage 101, so that upper polaroid 101 is with public
Forming the second electric field between common electrode 1042 makes the liquid crystal deflected up tilt predetermined angular, and now, backlight produces
Light can pass through display panels, and is projected to eyes of user, but, owing to liquid crystal slightly deflects, may result in dark-state
Light leak, contrast declines, thus realizes narrow visual display, can realize privacy screen effect.
Therefore, the invention provides a kind of display panels and device, by adulterating conducting particles at upper polaroid, and
Upper polaroid "on" position is controlled, it is possible between upper polaroid and the public electrode of TFT substrate, form electricity by driving chip
So that liquid crystal deflects, and to reduce contrast, therefore the present invention can keep away on the premise of realizing wide vision and narrow vision
Exempt from additional designs auxiliary ITO electrode, processing procedure can be simplified, and reduce cost.
The foregoing is only embodiments of the present invention, not thereby limit the scope of the claims of the present invention, every utilization is originally
Equivalent structure or equivalence flow process that description of the invention and accompanying drawing content are made convert, or are directly or indirectly used in what other were correlated with
Technical field, is the most in like manner included in the scope of patent protection of the present invention.
