Description
Technical field
The utility model is related to Screen Technology field, the flexible circuit board positive and negative of specifically a kind of screen is staggered black resistance
Body of light structure.
Background technology
Since display industry is to shielding and the market demand of high screen accounting comprehensively, with as shown in Figure 1 with the non-carrier of backlight
Liquid crystal display die set (side shines) shows AMOLED (face shines) with novel organic luminorphor as shown in Figure 2 and with such as Fig. 3 institutes
MiniLED (face shines) display shown exists evident from screen accounting disadvantage, this is because liquid crystal display LCD principles institute itself
It causes, needing the space of constantly diminution side emitting as the LCD of carrier using backlight approaches to be promoted in high screen accounting and final structure
AMOLED and MiniLED.
Refering to Fig. 4, back light module unit structure is by side-emitting LED collocation light guide plate and optical film material, finally by side light source
Uniform conversion is area source, and it is following parameter to be converted into area source to be related to primary structure core from the point light source of side-emitting LED：
LED light source net-pont design and LED light is avoided to cause light beam to generate by optical film material leaded light according to LED light emitting angles.
In the case that structure allow (i.e. non-comprehensive screen and screen accounting structure of less demanding) can in optical film material and
Design avoids light from importing more than the secret note of 0.6mm width with light blocking between FPC；The raising of screen accounting will mainly reduce in Fig. 5
The black bar shape being laterally arranged region, limit secret note structure space on optical film material, can cause LED effectively shine
The incident light generated under angle passes into optical film material and imports regular incident light in visible area, causes Integral luminous unevenness existing
As such as the black ellipse body region in Fig. 6.
Utility model content
It is staggered black light blocking body structure the purpose of this utility model is to provide a kind of flexible circuit board positive and negative of screen,
To solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions：
A kind of flexible circuit board positive and negative of screen is staggered black light blocking body structure, including flexible circuit board, the flexibility
For wiring board with black light blocking body in the attaching connection that is staggered of zigzag shape, the black light blocking body and light guide plate pass through double faced adhesive tape phase
Connection, the upper surface of black light blocking body is connected with diffusion barrier.
As further program of the utility model：The thickness of the double faced adhesive tape is 0.01-0.03mm.
As the utility model further scheme：Black light blocking body between the flexible circuit board and diffusion barrier is
Non- exceptionally straight state.
As the utility model further scheme：The black light blocking body is soft material.
As the utility model further scheme：The material of the black light blocking body is PI.
Compared with prior art, the utility model has the beneficial effects that：
1, since the black light blocking body between flexible circuit board and diffusion barrier is non-exceptionally straight state, and black light blocking body
With certain width, thereby, it is ensured that the flexibility of black light blocking body；
2, it since the material of black light blocking body is PI, is taken with being staggered for PI by being spread in the light blocking and structure of PI
Match, PI, which increases gum, to be ensured closely to attach with light guide plate, spread simultaneously and cost PI again and can prevent the attaching of PI and do not cause closely
Light leakage phenomena；
3, tradition can be substituted using the improved structure of the utility model using the improved structure of the utility model
Secret note light blocking is spread, secret note width spaces can be saved, so as to shorten luminous short lower border frames, screen accounting is promoted, adapts to
All kinds of mobile phones, industry control, vehicle-mounted, AR/VR, all kinds of comprehensive screens of white point.

Specific implementation mode
The technical solution of this patent is described in more detail With reference to embodiment.
The black light blocking body structure referring to Fig. 7, a kind of flexible circuit board positive and negative of screen is staggered, including flexible circuit board
1, the flexible circuit board 1 is with black light blocking body 2 in be staggered attaching connection, the black light blocking body 2 and the light guide plate of zigzag shape
3 are connected by double faced adhesive tape, and the upper surface of black light blocking body 2 is connected with diffusion barrier 4.The thickness of the double faced adhesive tape is 0.01-
0.03mm.Black light blocking body 2 between the flexible circuit board 1 and diffusion barrier 4 is non-exceptionally straight state.The black light blocking body
2 be soft material.The material of the black light blocking body 2 is PI, thickness 0.0125mm, has good light blocking effect, and to whole
Body structural thickness influences limited.
The operation principle of the utility model is：Since the black light blocking body 2 between flexible circuit board 1 and diffusion barrier 4 is non-
Exceptionally straight state, and black light blocking body 2 has certain width, thereby, it is ensured that the flexibility of black light blocking body 2；Since black hinders
The material of body of light 2 is PI, by spread in the light blocking and structure of PI with the collocation that be staggered of PI, PI increase gum ensure and
Light guide plate 3, which closely attaches, while the attaching of PI is costed PI again and can be prevented in diffusion does not lead to light leakage phenomena closely；Shield comprehensively, is short
Border does not have the useful space and goes light blocking come diffusion secret note structure (0.6mm-0.8mm) of arranging in pairs or groups, and uses changing for the utility model
Diffusion secret note structure is eliminated into type structure, diffusion is directly carried to black light blocking body 2, can met equally
Under border structure situations, FPC increases technique and cost without contrary class technique, can make screen still using front assembling
Module frame promote 0.8mm or more, promote screen accounting, it is all kinds of comprehensively to adapt to all kinds of mobile phones, industry control, vehicle-mounted, AR/VR, white point
Screen.
