Description
Technical field
The utility model relates to technical field of flat panel display, is specifically related to a kind of OLED screen body.
Background technology
In the design of OLED screen body, the configuration design of product needs the overall design of fit, during for narrow limit product design, when the width running into narrow limit is less than chip length, the result caused cannot complete the design of screen body often, or needs client to increase product design design, can not reach the requirement of client's original design, so just cause meeting the demand of market to narrow limit product, make portioned product demand can not order.
Existing conventional OLED screen body, the ornaments such as such as bracelet, chip (IC) nation fixed end project organization is as follows:
As shown in Figure 1, the chip (IC) 2 of screen body and flexible PCB 5 are positioned at screen object table terrace 3 position, namely, the length direction of chip 2 is parallel with the length direction of screen body viewing area (AA) 1, chip 2 is positioned at the long side of screen body viewing area (AA) 1, if this kind of arrangement makes screen body viewing area (AA) about 1 placed in the middle, increase is then needed to be positioned at the width shielded above body viewing area (AA) 1, to increase width equal with the width of screen object table terrace 3, otherwise screen body viewing area (AA) about 1 cannot be realized arrange between two parties.Screen body lead-in wire 4 all needs the Bump end causing chip 2, and screen body lead-in wire 4 is drawn from screen body 1 end, directly will cause the Bump end of chip 2.As shown in Figure 2.
During the screen body that design width is narrow in the prior art, there is following methods:
(1) by selecting the chip (IC) that length is less, the length of chip (IC) at least needs the long limit size being less than screen body viewing area (AA), fixed on screen body by COG (Chip On Glass) mode nation, be used for driving screen body viewing area (AA).Existing COG chip Bump Pitch (contact separation) is minimum is 25um, is generally 28um ~ 30um, if when running into high-resolution product, still cannot realize conventional nation fixed.
(2) realized by the mode of COF (Chip On FPC), chip (IC) is fixed in flexible circuit board, but the current technique of Pitch value of COF almost can only accomplish 30um, when running into high resolving power equally, screen body viewing area short of width is drawn to make all effective lead-in wires, causes realizing nation fixed.
Utility model content
For this reason, the utility model, in order to when not increasing screen body whole width size, realizes COG nation fixed, reaches screen body viewing area and arranges between two parties up and down.The utility model provides a kind of OLED screen body.
Adopt technical scheme as described below:
A kind of OLED screen body, comprise screen body viewing area, go between with the screen body that screen body is electrically connected and go between with described screen body the chip be connected, described chip is arranged at outside the narrow limit of described screen body viewing area, and described screen body lead-in wire is arranged along the long limit of described screen body viewing area.
The length dimension of described chip is greater than the narrow limit size of described screen body viewing area.
The length direction of described chip is parallel with the length direction of described screen body viewing area or is obliquely installed.
Described OLED screen body is also provided with I/O lead areas, and described I/O lead areas and described chip are arranged at the same side on narrow limit, described screen body viewing area, and the top of described I/O lead areas is provided with the metal level for reducing lead impedance.
Described metal level is the one in MoAlMo layer, Au layer, Ag layer, TiAlTi layer or Mo layer.
The utility model has following beneficial effect relative to prior art:
A. chip is arranged at the outside on screen narrow limit, body viewing area by the utility model, the exterior lateral area making screen body show head of district limit is exclusively used in COM/SEG cabling, can realize shielding the placed in the middle setting of body viewing area on narrow edge direction, meet the requirement of user to product design size.
B. the utility model is applicable to the situation that chip length size is greater than screen body narrow limit size, chip can carry out free placement in the narrow limit exterior lateral area of screen body viewing area, and carries out the lead-in wire of COM/SEG, and structure is simple, lead-in wire is convenient, is more conducive to the layout to longer scale chips.
C. the utility model is also provided with I/O lead areas on OLED screen body, I/O lead areas and chip are arranged at the same side of shielding narrow limit, body viewing area, the top of I/O lead areas is provided with the metal level for reducing lead impedance, because I/O lead areas lead-in wire is long, by the ITO layer number capable covering layer of metal layer of I/O lead areas, realize the reduction of lead impedance.
