Abstract
The utility model relates to a TFT LCD module that can direct reverse visual angle, does it include the conventional TN type TFT liquid crystal display of a slice, a drive TFT LCD's COG IC, a LED backlight, a FPC connector. TFT 6 visual angle directions of LCD display screen are best visual angle display orientation, 12 point visual angle direction for the gray scale direction of overturning, COG IC chip nation fix on TFT on the step of LCD display screen, FPC on have a TFT LCD's liquid crystal drive circuit, TFT piece upset back about the LCD display screen, the assembly is on a LED backlight. The utility model discloses the product mainly is the TFT liquid crystal display module based on conventional TN type, under the prerequisite of the PI layer friction orientation through revising the liquid crystal not, directly changes the TFT LCD module's of TN type best visual angle orientation, both with the utility model provides a LCD module at 6 former visual angles changes the LCD module at 12 visual angles into.
Description
Technical field
This utility model is related to a kind of TFT-LCD LCD MODULE, is specifically related to a kind of visual angle that is directly opposite
TFT liquid crystal modules.
Background technology
The very long phase of basic research of the development experience of TFT-LCD, after big production, commercialization is realized, TFT-LCD
Product is so that its is frivolous, environmentally friendly, high-performance the advantages of, size is done bigger and bigger, and application is more and more wider.Either undersized mobile phone
Screen or large-sized notebook computer or monitor, and the LCD TV for maximizing, are found everywhere the application of TFT-LCD.
TN types are a kind of most basic, most common TFT display patterns, be simple to manufacture, transmitance it is high, just have very in the PM LCD of early stage
Good application.TN display screens are worked using the optical activity of TN liquid crystal molecules, and the optical activity of TN not only affects the light of TN saturating
Rate is crossed, colour cast is there is also with the change of transmitance bad.This is outside one's consideration to the impact for showing except reducing transmitance and contrast,
Colour cast, including heterochromia phenomenon of the same frame under different visual angles, that is, the visual angle generally said can also be caused.For
TFT-LCD products, the TFT-LCD display screens of different visual angles are selected generally according to the product use direction of user.But on market
Most of TFT-LCD be all standard substance, view directions are fixed, if change view directions, need to pay huge mould
Tool expense or disposable mass customization are just capable of achieving the frictional direction of change PI layers.And the application visitor few for some order volumes
Family, changing visual angle just becomes a difficult problem.
Utility model content
To overcome deficiency of the prior art, the purpose of this utility model is to provide a kind of without changing the friction of PI layers
On the premise of direction, by changing the assembling mode and FPC designed in mirror image of TFT-LCD liquid crystal regarding for TFT-LCD is directly opposite
Angle.
To realize above-mentioned technical purpose, above-mentioned technique effect is reached, this utility model is achieved through the following technical solutions：
A kind of TFT liquid crystal modules for being directly opposite visual angle, including a piece of conventional 6 visual angles of TN types TFT-LCD show
Display screen, described one COG IC chip of TFT-LCD display screens bonding, 6 view directions of the TFT-LCD display screens are optimal
Visual angle display direction, 12 view directions are GTG reverses direction, it is characterised in that：The TFT-LCD display screens, by fluctuating plate
After upset, it is assemblied in LED backlight；Described COG IC chips by the FPC connector of 180 degree designed in mirror image with
TFT-LCD display screens connect, and load the drive circuit of TFT-LCD on described FPC, described COG IC chips by FPC with
Outside MCU is connected.
The characteristics of LCD display is a kind of conventional TN type TFT display screens, TN type liquid crystal display screens is in optimal viewing angle
Direction, with the increase of visual angle angle, image can shoal；And in the offside direction of optimal viewing angle, with the increase of visual angle angle,
Image can be deepened, and color overturns and causes image fault.The fluctuating plate direction that this utility model passes through change TFT-LCD, so as to
Directly change the view directions of TFT-LCD.
Described one COG IC of TFT-LCD display screens upper surface bonding.LCD display lower section arranges LED backlight, can be with
Working at night.TFT-LCD drive circuits are loaded on the FPC, because the TFT-LCD display screens need fluctuating plate to overturn,
Therefore FPC needs 180 degree designed in mirror image, is connected with outside MCU by FPC.
Description of the drawings
Fig. 1 shows structural representation of the present utility model.
In figure：1：The TFT-LCD at conventional visual angle；2：TFT-LCD behind reverse visual angle；3：FPC connector；4：LED-backlit
Source；5：COG IC chips.
Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments describing this utility model in detail.
It is shown in Figure 1, a kind of TFT liquid crystal modules for being directly opposite visual angle, it includes the TFT- at 6 visual angles of TN types
LCD display 1, the TFT-LCD display screens 1 are filled by upset fluctuating plate position, the mode for changing into TFT-LCD display screens 2
Match somebody with somebody, so that reversely view directions, optimal viewing angle direction is changed into 12 directions, as shown in Figure 1.
Glass step lower section one COG IC chip 5 of bonding of the TFT-LCD display screens 2, the COG IC chips 5 are led to
Cross a FPC connector 3 to be connected with outside MCU mainboards, described FPC connector 3 is because TFT-LCD display screens 1 are reversed dress
It is TFT-LCD2 with (the upset assembling of display screen fluctuating plate), and needs, using 180 degree designed in mirror image, to also need in FPC connector 3
Load driver circuit, the fit beneath LED backlights 4 of TFT-LCD 2 of the upset.
The TFT-LCD display screens 1 are 6 visual angles of TN types, are used by overturning the fluctuating plate direction of TFT-LCD, directly
Reversely TFT liquid crystal module view directions, are changed into 12 visual angles most preferably (as shown in label 2 in Fig. 1), described reverse visual angle side
To, it is not necessary to by the PI layer frictional directions for changing mould, directly changed by assembling mode, liquid crystal cell fluctuating plate directly overturns
, it is simple easily realize, it is cost-effective.
Described FPC connector 3, because after TFT-LCD display screens 1 overturn, being changed into the ITO after TFT-LCD display screens 2 electric
Pole also reversely, therefore needs to do 180 degree designed in mirror image simultaneously during FPC designs.
The LED backlight adopts six SMT (Surface Mounted of bottom-emission using backlight
Technology, surface installation technique) wick, brightness ensures in 350cd/m2。
Preferred embodiment of the present utility model is the foregoing is only, this utility model is not limited to, for this
For the technical staff in field, this utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
