For above-mentioned purpose of the present invention, feature and advantage can be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated, wherein:
Figure 1A is the synoptic diagram of existing display panel.
Figure 1B is the partial enlarged drawing of Figure 1A.
Fig. 2 A is the partial schematic diagram of the display panel of one embodiment of the invention.
Fig. 2 B is the synoptic diagram in the connection pad district of Fig. 2 A.

Embodiment
Fig. 2 A is the partial schematic diagram of the display panel of one embodiment of the invention.Please refer to Fig. 2 A, the display panel 2000 of present embodiment comprises a substrate 2100 and a plurality of chip bearing film 2200.The non-display area 2140 that substrate 2100 has viewing area 2120 and is positioned at viewing area 2,120 one sides.A plurality of connection pads district 2142 is arranged in the non-display area 2140.
Fig. 2 B is the synoptic diagram in the connection pad district of Fig. 2 A.Please also refer to Fig. 2 A and 2B, dispose a plurality of first pins 2144 and at least one the first displacement mark will 2146 in each connection pad district 2142, and the first displacement mark will 2146 is positioned at a side of all first pins 2144.Chip bearing film 2200 correspondences are attached at substrate 2100, and wherein each chip bearing film 2200 has a plurality of second pins 2220 and at least one the second displacement mark will 2240.
Fig. 2 C is the synoptic diagram of first and second displacement mark will of Fig. 2 B.Shown in Fig. 2 C, in the display panel 2000 of present embodiment, desirable situation is to utilize mode pressing first pin 2144 and second pin 2220 of hot pressing, and first pin 2144 can engage fully with second pin 2220, and this is the situation of good alignment spacing (Fine Pitch).
Yet, in the process of pressing first pin 2144 and second pin 2220, the breathing that first pin 2144 and second pin 2220 are understood because of material, and have second pin 2220 inaccurate easily with engaging of first pin 2144.Generally speaking, we are considered as the skew of second pin 2220 with it.
In order to detect the side-play amount of second pin 2220, we are designed to the form of a plurality of counting scale 2146a, 2146b, 2146c, 2146d, 2146e and 2146f with the first displacement mark will 2146, and the second displacement mark will 2240 is an index.Thus, the testing staff just can detect the side-play amount of second pin 2220 easily by the contraposition of the first displacement mark will 2146 and the second displacement mark will 2240.
For example, suppose that desirable situation is that the second displacement mark will 2240 is in alignment with between scale 2146c and the 2146d.When the second displacement mark will 2240 be in alignment with scale 2146e and 2146f between the time, we just can know: in the pressing process, first pin 2144 and the 2220 generating material breathing of second pin make that second pin 2220 after the pressing is offset default position.By counting scale and index, the testing staff can utilize simple visual type, just can detect the situation that second pin 2220 has skew easily.In addition, more can detect the side-play amount of second pin 2220 easily.In other embodiments, except whether visual second pin 2220 that detects that utilizes the testing staff is offset and side-play amount, also can be to utilize computer or other modes to detect.
In addition, in order to allow the testing staff can the identification of more convenient ground, therefore the first displacement mark will 2146 in Fig. 2 B has two, and the corresponding second displacement mark will 2240 also has two, and these two first displacement mark will 2146 lay respectively at the both sides of all first pins 2144, and two second displacement mark will 2240 lays respectively at the both sides of all second pins 2220.Therefore, the testing staff can utilize the first displacement mark will 2146 of one group of correspondence wherein and the second displacement mark will 2240 to detect to get final product easily.
Present embodiment is to serve as the counting scale with the first displacement mark will 2146, and the second displacement mark will 2240 illustrates for index.The present technique field has knows the knowledgeable usually, after reading the embodiment of this instructions, can be easily with the first displacement mark will 2146 and the second displacement mark will, 2240 usefulness other shape and count scale, mode substitutes.
It should be noted that we can also utilize above-mentioned detection method to define a pickup zone 2148 in connection pad district 2142, to promote the pin joint rate of display panel 2000.Simply, pickup zone 2148 is exactly behind pressing first pin 2144 and second pin 2220, the zone of second pin, 2220 no side-play amounts.In pickup zone 2148, first pin 2144 and second pin 2220 behind the joint have accurate good alignment spacing.
After defining pickup zone 2148, we can also be in the manufacturing process of display panel 2000, optionally first pin 2144 only is made in the pickup zone 2148 in the connection pad district 2142, or optionally pressing is positioned at first pin 2144 and second pin 2220 of pickup zone 2148, just can improve the joint rate of pin.After pin joint rate improved, the yield of display panel 2000 also and then improved, and can also save that display panel 2000 has flaw simultaneously and needed the man-hour and the manpower of heavy industry.
In addition, we also can adjust the quantity and the spacing of first pin 2144 according to circumstances, and the quantity of corresponding second pin 2220 and spacing.So, not only can dwindle the size of substrate 2100 and chip bearing film 2200, also can save the material cost of making pin.
In sum, the method for the pin joint of the detection method of the pin of display panel of the present invention, display panel joint and display panel has following advantage at least:
One, the testing staff can need rework to judge display panel whether flaw to be arranged by the displacement mark will side-play amount of the pin that engages of identification easily, can save detection man-hour and manpower.
Two, utilize the side-play amount of the pin that engages, in the connection pad district of substrate, define the pickup zone, and be positioned at the pin that engages in this district, have accurate good alignment spacing.
Three, only pressing is positioned at the pin of pickup zone, or only first pin is made in the pickup zone, can improve the joint rate of pin, saves the man-hour and the manpower of display panel heavy industry.
Four, adjust the quantity and the spacing of first pin and corresponding second pin that are positioned at the pickup zone according to circumstances, the size that can dwindle substrate and chip bearing film also can be saved the material cost of making pin simultaneously.
Though the present invention discloses as above with preferred embodiment; right its is not in order to limit the present invention; any the technical staff in the technical field; without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is as the criterion when defining with claims.
