Embodiment
To make those skilled in the art more fully understand the technical solution of the utility model, under
Face is described in further detail with reference to the drawings and specific embodiments to the utility model.
Embodiment 1：
As shown in Figure 1 and Figure 2, the present embodiment provides a kind of display module, can be used to prepare display device.The display module
With the display surface for being shown and away from the back side of display surface.The back side of display module, which is provided with, to be used to mark contraposition device
The alignment mark 1 of 2 para postion；Alignment mark 1 includes multiple contrapositions located at diverse location and identified, for determining alignment device
The bit errors of part 2.
Wherein, display module can be liquid crystal display die set, or other display modules such as OLED display modules,
This is not specifically limited.
Wherein, aligning the finger of device 2 needs to be arranged at the device of the ad-hoc location (para postion) of display module, such as flexible
Circuit board (FPC), printed circuit board (PCB) etc., it can also be other devices for needing to align to align device 2 certainly, herein not
Repeat again.
And alignment mark 1 is the visual mark in display module, it includes multiple visual contraposition marks, is used for
The para postion of mark contraposition device 2 and the bit errors for determining contraposition device 2.
In the present embodiment, illustrated exemplified by aligning device 2 and being FPC.
Display module has the one side (display surface) that can be shown, and away from the back side of display surface.In FPC and liquid crystal
Show that the display surface of module carries out bonding later, it is necessary to which the part that FPC is protruded to display module is turned over by the display surface of display module
The display module back side is folded to, and is aligned to ad-hoc location (para postion).In the present embodiment, in the contraposition position at the display module back side
The place of putting is provided with alignment mark 1, so as to can quickly and accurately determine to turn down position when FPC is turned down.
In actual mechanical process, certain error (bit errors) occurs in FPC turnovers, and the bit errors are with showing
The yields of device is directly related.In the present embodiment, alignment mark 1 include it is multiple contraposition identify, after being turned down by FPC with it is each right
The position relationship of bit identification, such as the contraposition by determining to overlap with the FPC after turnover identify, or after FPC turnovers and each
The distance of mark is aligned, can precisely determine FPC turnover error.Aligning accuracy can accurately be determined according to turnover error,
So as to carry out quality grading to display device according to the aligning accuracy.It is understood that turnover error is smaller, turnover essence
Degree is higher, and the display device quality of prepared completion is also better.
Preferably, fringe region of the alignment mark 1 located at the back side of display module.
Why FPC needs to align when turning down, and is in order that the signal input part of the FPC after turnover can be in display module
The ad-hoc location of fringe region protrudes, so as to after completion display device is prepared, be easy to the signal input part input signal.
Alignment mark 1 is located at fringe region, alignment mark 1 can be made closer to signal input part, so that FPC contrapositions are more smart
It is accurate.
Preferably, as shown in figure 1, it is multiple contraposition mark in the first direction (vertical direction in Fig. 1) interval be uniformly arranged.
Wherein, the direction of error is easily produced when first direction is preferably and aligned, such as shown in Fig. 2, FPC would generally be vertical when turning down
In producing error on the direction of turn-line (turn-line direction is horizontal direction in Fig. 1, and first direction is vertical direction), then may be used
The direction is set to first direction, make it is multiple contraposition mark set in the direction, so as to FPC turnover contraposition after, according to its
The contraposition mark of coincidence determines its bit errors.
Spacing distance between contraposition mark is related to the accuracy of detection of bit errors, and spacing distance is nearer, then measured
Bit errors it is more accurate, accuracy of detection is higher.
It is understood that contraposition mark is more, detectable error range is bigger.
Preferably, contraposition mark includes scale part and identification division.Identification division is used for home position, and its shape can be with
For line segment, round dot etc., it is not limited specifically；Scale part is used for the positional information for marking explanation identification division, and it is to show mould
(determine) to be labeled explanation to contraposition mark according to actual conditions on the basis of certain point or line segment in group.For example, when FPC turnovers pair
During position, a side (in Fig. 2 lower side of display module) vertical with FPC turnovers direction is right as benchmark using in display module
Contraposition mark is labeled.Information according to being overlapped after FPC turnover contrapositions or close contraposition identifies (is specially that this is right
The scale part of bit identification), you can directly to determine bit errors.For example, FPC should be aligned to contraposition corresponding to scale 50
Mark, and actually align to contraposition mark corresponding to scale 52, then bit errors are 2.Meanwhile prepare different display devices
When, different is required to FPC para postion, then alignment mark 1 need not be reset, directly by register guide corresponding to different scales
Knowledge is aligned as standard para postion.
Preferably, the display module includes display panel and glue frame, and display panel has the display surface for being used for being shown；
Deviate from the glue frame of display surface side located at display panel, alignment mark 1 is located at glue frame on the side of display panel.
FPC generally directly contacts at the back side of turnover to display module with the glue frame of display module, therefore can be by register guide
Note 1 is directly arranged in glue frame, is aligned when being turned down in order to FPC.
Preferably, the display module includes：Located at the metal-back of display module fringe region, alignment mark 1 is located at metal
On shell.
As shown in the above, the main purpose for needing to align after FPC turnovers is the signal incoming end for making FPC specific
Position protrudes from the fringe region of display module, and under normal circumstances, the fringe region of display module is provided with metal-back (lower iron
Part), therefore can be aligned by alignment mark 1 on metal-back when being turned down in order to FPC.
The present embodiment provides a kind of display module, and the back side of display module is provided with multiple contrapositions and identified, and passes through the register guide
Knowledge can help to align the progress accurate contraposition of device 2.Meanwhile according to contraposition device 2 and the position relationship of each contraposition mark, can be with
Bit errors when contraposition device 2 is aligned precisely are determined, so as to effectively improve the yields of product, meanwhile, also can basis
The bit errors carry out quality grading, simplify Quality Detection technique.
Embodiment 2：
As shown in Figure 1 and Figure 2, the present embodiment provides a kind of display device, including the display module provided in embodiment 1.It is aobvious
Showing device can be Electronic Paper, oled panel, mobile phone, tablet personal computer, television set, display, notebook computer, DPF,
