Abstract
The invention relates to a TFT (Thin Film Transistor) liquid crystal module capable of directly reversing a view angle. The TFT liquid crystal module comprises a conventional TN type TFT liquid crystal display screen, a COG IC (Chip on Glass Integrated Circuit) for driving a TFT-LCD (Thin Film Transistor-Liquid Crystal Display), an LED (Light Emitting Diode) backlight source and an FPC (Flexible Printed Circuit) connector. The six o'clock view angle direction of the TFT-LCD is an optimal view angle display direction and the twelve o'clock view angle direction of the TFT-LCD is a gray scale overturning direction; a COG IC chip is bound on a step of the TFT-LCD; the FPC is provided with a liquid crystal driving circuit with the TFT-LCD; after upper and lower sheets of the TFT-LCD are overturned, the TFT-LCD is assembled on one LED backlight source. The product provided by the invention is the TFT liquid crystal module based on a conventional TN type; under the condition that a friction direction of a PI layer of a liquid crystal is not changed, the optimal view angle display direction of the TN type TFT liquid crystal module is directly changed; the liquid crystal module with an original six o'clock view angle is changed into the liquid crystal module with a twelve o'clock view angle.
Description
Technical field
The present invention relates to a kind of tft-lcd LCD MODULE, it is specifically related to a kind of tft liquid being directly opposite visual angle
Brilliant module.
Background technology
The very long phase of basic research of the development experience of tft-lcd, realize big produce, after commercialization, tft-lcd
Product is so that it is frivolous, environmental protection, 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 maximizing, are found everywhere the application of tft-lcd.
Tn type is a kind of the most basic, most common tft display pattern, be simple to manufacture, transmitance high, just have very in the pm lcd of early stage
Good application.Tn display screen is to be worked using the optical activity of tn liquid crystal molecule, and the light that the optical activity of tn not only affects tn is saturating
Cross rate, there is also colour cast with the change of transmitance bad.This impact to display is outside one's consideration except reducing transmitance and contrast,
Colour cast also can be caused, including heterochromia phenomenon under different visual angles for the same frame, that is, the visual angle generally said.For
Tft-lcd product, generally according to the product use direction of user, to select the tft-lcd display screen of different visual angles.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 just can achieve the frictional direction changing pi layer.And for the few application visitor of some order volume
Family, changing visual angle just becomes a difficult problem.
Content of the invention
For overcoming deficiency of the prior art, it is an object of the invention to provide one kind is without change pi layer frictional direction
On the premise of, by changing assembling mode and the fpc designed in mirror image of tft-lcd liquid crystal, to be directly opposite the visual angle of tft-lcd.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of tft liquid crystal module being directly opposite visual angle, the tft-lcd including a piece of conventional 6 points of visual angles of tn type shows
Display screen, described one cog ic chip of tft-lcd display screen bonding, described 6 points of view directions of tft-lcd display screen are optimal
Visual angle display direction, 12 points of view directions be GTG reverses direction it is characterised in that: described tft-lcd display screen, by fluctuating plate
After upset, it is assemblied on led backlight；Described cog ic chip by the fpc adapter of a 180 degree designed in mirror image with
Tft-lcd display screen connects, and described fpc loads the drive circuit of tft-lcd, described cog ic chip pass through fpc with
Outside mcu is connected.
Described lcd display screen, is a kind of conventional tn type tft display screen, the feature of tn type liquid crystal display screen is in optimal viewing angle
Direction, with the increase of visual angle angle, image can shoal；And the offside direction in optimal viewing angle, with the increase of visual angle angle,
Image can deepen, and color overturns and leads to image fault.The present invention passes through to change the fluctuating plate direction of tft-lcd, thus directly
Change the view directions of tft-lcd.
Described tft-lcd one cog ic of display screen upper surface bonding.Led backlight is set below lcd display screen, permissible
Working at night.Tft-lcd drive circuit is loaded on described fpc, because described tft-lcd display screen needs fluctuating plate to overturn,
Therefore fpc needs 180 degree designed in mirror image, is connected with outside mcu by fpc.
Brief description
Fig. 1 shows the structural representation of the present invention.
In figure: 1: the tft-lcd at conventional visual angle；2: the reversely tft-lcd behind visual angle；3:fpc adapter；4:led backlight
Source；5:cog ic chip.
Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, to describe the present invention in detail.
Shown in Figure 1, a kind of tft liquid crystal module being directly opposite visual angle, it includes the tft- at 6 points of visual angles of tn type
Lcd display screen 1, described tft-lcd display screen 1 passes through to overturn fluctuating plate position, and the mode changing into tft-lcd display screen 2 fills
Join, so that reverse view directions, optimal viewing angle direction is changed into 12 points of directions, as shown in Figure 1.
One cog ic chip 5 of bonding below the glass step of described tft-lcd display screen 2, described cog ic chip 5 leads to
Cross a fpc adapter 3 to be connected with outside mcu mainboard, described fpc adapter 3 is because tft-lcd display screen 1 is reversed dress
Joining (the upset assembling of display screen fluctuating plate) is tft-lcd2, and needs, using 180 degree designed in mirror image, fpc adapter 3 to also need to
Load driver circuit, the tft-lcd 2 fit beneath led backlight 4 of described upset.
Described tft-lcd display screen 1 is 6 points of visual angles of tn type, is used by overturning the fluctuating plate direction of tft-lcd, directly
Reversely tft liquid crystal module view directions, are changed into that 12 points of visual angles are optimal (as shown in label 2 in Fig. 1), described reverse visual angle side
To it is not necessary to by the pi layer frictional direction of change mould, directly be changed by assembling mode, liquid crystal cell fluctuating plate directly overturns
, simply easily realize, cost-effective.
Described fpc adapter 3, because after tft-lcd display screen 1 upset, is changed into the electricity of the ito after tft-lcd display screen 2
Pole is also simultaneously reverse, needs to do 180 degree designed in mirror image during therefore fpc design.
Described led backlight adopts backlight to adopt six smt (surface mounted of bottom-emission
Technology, surface installation technique) wick, brightness ensures in 350cd/m2.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
