The utility model aim is realized, the embodiments will be further described with reference to the accompanying drawings for functional characteristics and advantage.

Specific embodiment

Below in conjunction with attached drawing and specific embodiment, the utility model is described further.In preferred embodiment Cited such as "upper", "lower", "left", "right", " centre " and " one " term, only being illustrated convenient for narration, rather than to The enforceable range of the utility model is limited, relativeness is altered or modified, under the content of no substantial changes in technology, when also It is considered as the enforceable scope of the utility model.

As depicted in figs. 1 and 2, the double TFT LCDs of antireflection splicing item screen include two-sided using antireflection process One sheet glass 101, two panels liquid-crystalline glasses (it includes the first liquid-crystalline glasses 102 and the second liquid-crystalline glasses 103), two backlight modules (it includes the first backlight module 104 and the second backlight module 105), shuangping san mainboard 106, master control mainboard 110 and power supply 112, the two panels liquid-crystalline glasses mutually splice, and are superimposed with each other with glass 101, and in a sheet glass 101 and two panels liquid crystal glass Optical glue is filled between glass, the backlight module includes constant current plate 111 and several lamp bars, and the constant current plate 111 passes through Electric current is provided to the LED lamp bead 107 of lamp bar, so that LED light is shinny, the shuangping san mainboard 106 passes through screen line and two panels liquid The logic card of crystal glass is attached, and to drive two panels liquid-crystalline glasses normally to light, (it includes for the logic cards of two panels liquid-crystalline glasses First logic card 108 and the second logic card 109) it is connected respectively with master control mainboard 110, the power supply 112 is master control mainboard 110 It powers with constant current plate 111.

In specific implementation, the lamp bar is attached on aluminum substrate by multiple LED lamp beads 107 and is formed.

Due to the difference of liquid crystal material and backlight material, two 101 colors of liquid-crystalline glasses are formed there may be difference, By the output of adjustment signal, gamma correction is carried out to the output of signal, to reach the consistent of two pieces of 101 display colors of glass Property.In specific implementation, the shuangping san mainboard 106 is used to receive the brightness of the two panels liquid-crystalline glasses acquired by acquisition module Parameter, and two panels liquid-crystalline glasses are adjusted according to luminance parameter, so that the display color of two panels liquid-crystalline glasses is consistent.

Preferably, the constant current plate 111 and lamp bar that described two backlight modules include are all the same, to guarantee the system of backlight illumination One.

The two panels liquid-crystalline glasses are obtained by cutting, and the cutting of the side of the separate splicing of the two panels liquid-crystalline glasses It is sealed using ultraviolet curing glue in face.Display boundary 4mm of the cut surface apart from liquid-crystalline glasses 101.

In order to enable the reflectivity of liquid-crystalline glasses 101 is low, so that screen definition, antireflection, the optical glue are OCA light Glue is learned, which is used for the extraordinary viscose glue of cementing transparent optical element (such as camera lens) Agent.It is good in 90% or more, cementing strength to require colorless and transparent, light transmission rate, can solidify under room temperature or medium temperature, and have The features such as cure shrinkage is small.

In specific implementation, the glass 101 realizes counnter attack radiation treatment using AG double-sided coating technique, can also adopt certainly Counnter attack radiation treatment otherwise is carried out to glass 10l.

In order to allow technical field this realization the technical solution of the utility model well of this field, one is illustrated in detail below The production method for the double TFT LCDs of antireflection splicing item screen that embodiment provides:

Glass 101 uses AG double-sided coating process, due to optics fitting to be carried out, it is desirable that the flatness of glass 101 And the flatness of plated film has very high requirement；Then the cutting of size needed for being carried out to two panels liquid-crystalline glasses, then to liquid crystal glass The right of glass 101 is cut, this cutting position is 4mm or so from display position, followed by cut surface is carried out sealing and Curing process；It first shows that the poor glue of outer edge mobility makes a frame in glass 101, is poured into inside frame Mobility is relatively good, the optical glue of precalculated quantity.By equipment simultaneously by the liquid-crystalline glasses 101 of two pieces of well cuttings It is laid flat in optical glue according to pre-designed position with the direction of respective 180 degree, then carries out the de-bubble of optical glue Processing and horizontal processing；The pixel difference of first and last line between two liquid-crystalline glasses 101 is within half-pixel.Due to Optical glue is that (glue acts between glass 101 and two liquid-crystalline glasses 101, reflection for a kind of glue that reflectivity is extremely low Rate is low, so that screen definition, antireflection), so can achieve the effect that air is bonded under 1500 brightness in the case where brightness 600 Fruit；Two backlight modules use the same constant current plate 111 and lamp bar, to guarantee the unification of backlight illumination.Backlight material and LED light Pearl 107 will strictly select a very narrow range, in allowed limits with the brightness for guaranteeing backlight and coloration.They and stickup Good glass 101 forms a display module by fixed plate；Shuangping san mainboard 106 passes through screen line and two liquid-crystalline glasses 101 logic card is attached, so that two liquid-crystalline glasses 101 of driving are normally lighted.We utilize this block shuangping san mainboard 106 and the acquisition equipment of outside the difference of two glass 101 is corrected, reach the consistent effect of display color.

Although those skilled in the art should manage the foregoing describe specific embodiment of the present utility model Solution, these are merely examples, various changes or modifications can be made to present embodiment, without departing from the original of the utility model Reason and essence, the protection scope of the utility model are only limited by the claims that follow.
