Furthermore, the terms "first," "second," and the like are used solely to distinguish one from another, and are not to be construed as indicating or implying relative importance.
It should be noted that, in case of conflict, different features in the embodiments of the present application may be combined with each other.
Referring to fig. 1, fig. 1 shows a schematic diagram of a partial Film structure and an Area size of a display panel 1', including an Active Area (AA) 10' and a non-display Area 20', where the display panel 1' may include a screen 11', a touch layer 12' and a polarizer 13' that are sequentially stacked, where the screen 11' may include an array substrate layer, a light emitting device layer and a package cover plate that are sequentially stacked, and the touch layer 12' may be located on the package cover plate, where the array substrate layer is a Thin Film Transistor (TFT) array substrate layer fabricated on a Low Temperature polysilicon Layer (LTPS).
The width of the non-display area 20' at the periphery (e.g., the lower end) of the display panel 1' is formed by the cutting margin A1 of the array substrate layer, the width A2 of the display bonding area 111', the distance A3 between the display bonding area 111' and the touch layer 12', the cutting margin A4 of the package cover plate, the width A5 of the touch bonding area 121', the distance A6 between the touch bonding area 121' and the polarizer 13', and the distance A7 between the effective display area 10' and the side of the polarizer 13' away from the effective display area 10 '.
Among the distances, reducing the distance A6 between the touch bonding area 121' and the polarizer 13' is a better way to achieve the super-narrow frame of the display panel 1', however, the phenomena of poor display and poor appearance may occur after reducing the distance between the touch bonding area 121' and the polarizer 13 '.
The inventors have analyzed the above display defects and appearance defects, and as shown in fig. 2 and fig. 3, the touch layer 12 'includes a touch area 12A', a touch bonding area 12B ', and a touch wiring area 12C' therebetween, and the polarizer 13 'is located on the touch area 12A'. Fig. 2 shows a bonding diagram when the distance between the touch bonding area 12B ' and the polarizer 13' is not shortened, and fig. 3 shows a bonding diagram when the distance between the touch bonding area 12B ' and the polarizer 13' is shortened (i.e., the distance between the touch bonding area 12B ' and the touch area 12A ' is shortened, and the width of the touch wiring area 12C ' is reduced). As can be seen from fig. 2, during bonding, the bonding ram 40 'may protrude toward one end of the polarizer 13' relative to the flexible circuit board 30', and therefore, the distance between the touch-sensing bonding area 12B' and the polarizer 13 'is set to be large in the prior art, so as to prevent the protruding bonding ram 40' from acting on the polarizer 13 'to scald the polarizer 13'. As shown in fig. 3, when the distance between the touch bonding area 12B ' and the polarizer 13' is shortened, the bonding press head 40' of the protruding portion may directly act on the polarizer 13', the polarizer 13' may be scalded by the high temperature of the bonding press head 40', the polarization performance of the polarizer 13' may be changed, and poor display may be caused, and in addition, the display panel 1' may be yellowed after the polarizer is scalded, which may cause poor appearance of the display panel 1 '.
In order to solve the technical problem, the inventor designs the following technical scheme, and the bonding pressure head is prevented from directly acting on the polarizer during bonding by changing the thickness of the flexible circuit board corresponding to the golden finger area.
