A kind of short in size screen and the soft vehicle LCD of the picture boundaries of TFT combinationTechnical field
The present invention relates to vehicle LCD, the picture boundaries combined more particularly to a kind of short in size screen and TFT are softVehicle LCD.
Background technique
Vehicle-mounted full liquid crystal display is that tradition machinery instrument board is substituted for the large-sized LCD screen of a monolith, not only may be usedWith display driving basic information, and it can show the contents such as navigation information and entertainment information.The setting of this block LCD screen is being drivenThe front for the person of sailing largely facilitates driver and browses information, improves the safety of driving.
Since VA-LCD die sinking expense is lower, size is versatile and flexible, and vehicle LCD is with large scale VA-LCD collocationThe structure of TFT is in the majority.It is black when VA-LCD is not powered, is white after power-up, it is often corresponding in VA-LCD in the prior artThe position setting monolith display of TFT shows picture to penetrate lower section TFT, and from overall appearance, the display picture of TFT is penetratedVA-LCD has apparent surrounding boundary, to the vision conflict that people is lofty.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of soft vehicle-mounted liquid of the picture boundaries of short in size screen and TFT combinationCrystal display, be able to solve it is existing in the prior art " display picture there is technical issues that obvious boundary.

Further, first grading structure includes that multiple circles hollow out unit, and circle hollows out the diameter of unit from firstGrading structure edge to inside gradually becomes smaller, and two neighboring circle hollows out the spacing between unit from the first grading structure edge extremelyInside becomes larger.
Further, the diameter that the circle hollows out unit is 0.1~0.5mm, and two neighboring circle hollows out between unitSpacing is 0.1~2.0mm.
Further, first grading structure includes that a vertically disposed column crouch and trapezoidal hollow out unit.
Further, the trapezoidal bottom edge length for hollowing out unit that crouches is 0.2~1.0mm, and top margin length is 0~0.1mm, highDegree is 0.5~5.0mm, and the two neighboring trapezoidal spacing hollowed out between unit that crouches is 0.01~0.05mm.
Further, second grading structure includes that multiple circles hollow out unit, and circle hollows out the diameter of unit from secondGrading structure edge to inside gradually becomes smaller, and two neighboring circle hollows out the spacing between unit from the second grading structure edge extremelyInside becomes larger.
Further, the diameter that the circle hollows out unit is 0.1~0.5mm, and two neighboring circle hollows out between unitSpacing is 0.1~2.0mm.
Further, second grading structure includes that a vertically disposed column crouch and trapezoidal hollow out unit.
Further, the trapezoidal bottom edge length for hollowing out unit that crouches is 0.2~1.0mm, and top margin length is 0~0.1mm, highDegree is 0.5~5.0mm, and the two neighboring trapezoidal spacing hollowed out between unit that crouches is 0.01~0.05mm.
Further, the degree of polarization of the preceding polarizing film is 95%~99.99%.
The utility model has the advantages that the vehicle-mounted liquid crystal display soft the invention discloses the picture boundaries that a kind of short in size screen and TFT are combinedDevice, the edge of the part of face TFT mould group is face TFT mould group in the first grading structure and/or rear ITO layer in preceding ITO layerPartial edge is the second grading structure, TFT can be made to show that the boundary after picture transmission becomes soft in this way, to mitigateVision conflict.

Specific embodiment
Present embodiment discloses the soft vehicle-mounted liquid crystal display of picture boundaries of a kind of short in size screen and TFT combinationDevice, as shown in Figure 1, including preceding polarizing film 1 and rear polarizer 9, the bottom of preceding polarizing film 1 is equipped with front glass 2, rear polarizer 9Top is equipped with rear glass 8, and the bottom of rear polarizer 9 is equipped with TFT mould group 10, liquid crystal layer 5 is equipped between front glass 2 and rear glass 8,ITO layer 3 and preceding PI layer 4 before being successively arranged from top to down between liquid crystal layer 5 and front glass 2, between liquid crystal layer 5 and rear glass 8 certainlyOn be successively arranged rear PI layer 6 and rear ITO layer 7 down；The edge of the part of face TFT mould group 10 is the first gradual change in preceding ITO layer 3The edge of the part of face TFT mould group 10 is the second grading structure in structure and/or rear ITO layer 7.The shape of liquid crystal layer 5 can be withFor H-shaped.The degree of polarization of preceding polarizing film 1 is 95%~99.99%.Wherein, short in size screen includes preceding polarizing film 1, front glass 2, preceding ITOLayer 3, preceding PI layer 4, liquid crystal layer 5, rear PI layer 6, rear ITO layer 7, rear glass 8 and rear polarizer 9.
First grading structure there are two types of embodiment, the embodiment 1 of respectively the first grading structure and the first grading structureEmbodiment 2.
The embodiment 1 of first grading structure:
In the present embodiment, the first grading structure includes that multiple circles hollow out unit 31, as shown in figure 3, circle hollows out unit31 diameter d2 gradually becomes smaller from the first grading structure edge to inside, and two neighboring circle hollows out the spacing d1 between unit 31It is become larger from the first grading structure edge to inside.The diameter d2 that circle hollows out unit 31 is 0.1~0.5mm, two neighboringIt is 0.1~2.0mm that circle, which hollows out the spacing d1 between unit 31,.
The embodiment 2 of first grading structure:
In the present embodiment, the first grading structure include it is vertically disposed one column crouch it is trapezoidal hollow out unit 32, as shown in Figure 2.The trapezoidal bottom edge length h1 for hollowing out unit 32 that crouches be 0.2~1.0mm, top margin length h2 be 0~0.1mm, height L be 0.5~5.0mm, the two neighboring trapezoidal spacing d hollowed out between unit 32 that crouches is 0.01~0.05mm.
Second grading structure there are two types of embodiment, the embodiment 1 of respectively the second grading structure and the second grading structureEmbodiment 2.
The embodiment 1 of second grading structure:
In the present embodiment, the second grading structure includes that multiple circles hollow out unit, and circle hollows out the diameter of unit from secondGrading structure edge to inside gradually becomes smaller, and two neighboring circle hollows out the spacing between unit from the second grading structure edge extremelyInside becomes larger.The diameter that circle hollows out unit is 0.1~0.5mm, and two neighboring circle hollows out the spacing between unit and is0.1~2.0mm.
The embodiment 2 of second grading structure:
In the present embodiment, the second grading structure includes that a vertically disposed column crouch and trapezoidal hollow out unit.It crouches and trapezoidal hollows out listThe bottom edge length of member is 0.2~1.0mm, and it is highly 0.5~5.0mm that top margin length, which is 0~0.1mm, two neighboring trapezoidal digging of crouchingSpacing between dummy cell is 0.01~0.05mm.
After TFT mould group 10 and short in size screen are driven, the liquid crystal of corresponding grading structure point in preceding ITO layer 3 and rear ITO layer 7Son vertical arrangement, polarised light can not pass through.After TFT mould group 10 and short in size screen are driven, nothing in preceding ITO layer 3 and rear ITO layer 7Liquid crystal molecule at grading structure becomes oblique arrangement, and polarised light can pass through, namely from TFT mould group 10 be emitted polarised light according toIt is secondary to penetrate rear polarizer 9, rear glass 8, rear ITO layer 7, rear PI layer 6, liquid crystal layer 5, preceding PI layer 4, preceding ITO layer 3 and front glass 2, mostPreceding polarizing film 1 is passed through eventually, and the picture of TFT mould group 10 is visible.Because of the first grading structure and/or the second grading structure, so that TFTPicture boundaries become soft, alleviate vision conflict.
