Technical field
The present invention relates to display screen technology fields, more particularly to a kind of screen comprehensively.
Background technique
Currently, screen has been mainstream comprehensively.In order to realize comprehensive screen, it usually needs reduce the height of display screen lower frame.
This just need to shed on the source line for determining lower frame height area's height, driving chip height and golden finger height reduce.
The mainstream scheme for reducing lower frame height at present is, by the driving chip of display screen by COF technique, to move away from display
Screen, is placed on winding displacement, as long as the lower frame of such display screen stays point space, meets source line and sheds area's height and golden finger
Height.In addition, in order to further decrease lower frame height, it will usually using the less LTPS screen of source line or
AMOLED display screen can be such that the area's height that sheds of source line is reduced in this way.By both methods, can make following
Frame becomes very little, reaches 2mm or so or smaller, greatly improves screen accounting.But COF technique+LPTS screen or COF technique+
AMOLED screen, the use of two schemes, there are two main disadvantage, first is that cost can be made to improve not using COF technique
It is few；Second is, in order to reach screen effect comprehensively, the area's height that sheds of source line must also be reduced simultaneously, thus mesh
Before can only select LTPS screen or AMOLED screen, the screen of A-Si cannot be selected, greatly limit use scope.
