Description

FIELD OF THE INVENTION

The present invention relates to the field of display technology, and particularly relates to a detecting apparatus and a detecting method.

BACKGROUND OF THE INVENTION

Currently, in the fabrication of a panel, an electrical detection needs to be performed on a display substrate or the assembled panel before bonding a driving chip, that is, a signal detecting device inputs a signal into the panel through a terminal of a signal line of the panel, so as to detect whether a defect exists in the panel.

In the process of performing the electric detection, a shorting bar is generally used to lead a signal line to a relatively spacious region, and a detecting probe is connected to a terminal of the shorting bar. Since intervals between terminals of the shorting bars may be relatively large, demand on accuracy of the detecting probes is relatively low. After the electric detection is finished, the shorting bar circuits need to be cut off or removed by way of laser cutting, and meanwhile, it is necessary to use a corresponding detecting apparatus to detect the areas of the shorting bar circuits, so as to ensure that the shorting bar circuits in the panel are completely cut off.

FIG. 1 is a schematic diagram of a structure of a detecting apparatus in the prior art, and FIG. 2 is a schematic diagram of a detecting image generated by an image generating unit in the detecting apparatus shown in FIG. 1. As shown in FIGS. 1 and 2, the detecting apparatus comprises: a base 3, an image generating unit 6 (which is generally a camera) and a detecting unit 7. Positioning pillars 4 for supporting a lower surface of a panel 1 and positioning the panel 1 are provided on the base 3. The image generating unit 6 is arranged above the panel 1, and is connected to the detecting unit 7. The detecting process of the detecting apparatus is as follows. At first, the image generating unit 6 emits detecting light 5, which lasts for a relatively short time, onto the area of a shorting bar circuit 2 on the panel, at this point, the shorting bar circuit 2 remaining on the panel will reflect the detecting light 5 to the image generating unit 6, while for the area of the panel where no shorting bar circuit 2 remains, the detecting light 5 will be transmitted to the base 3 directly and absorbed by the base 3. Then, the image generating unit 6 generates a detecting image of the area of the shorting bar circuit 2 on the panel according to the received reflected detecting light 5, and in the detecting image, it is white at a position corresponding to a part of the panel where the shorting bar circuit 2 remains, and it is back at a position corresponding to a part of the panel where no shorting bar circuit 2 remains. At last, the detecting unit 7 can determine whether the shorting bar circuit 2 is cut off based on the detecting image. Specifically, when it is black at a position that corresponds to a laser cutting area 20 in the detecting image, it can be determined that the shorting bar circuit 2 is cut off.

However, in a practical detecting process, since the detecting light emitted from the image generating unit 6 lasts for a short time and is of low brightness, and meanwhile wires in the shorting bar circuit 2 are relatively thin, the effect of reflecting of the detecting light 5 by the shorting bar circuit 2 is not good, and therefore, the detecting image generated by the image generating unit 6 cannot reflect the actual situation of the shorting bar circuit 2 accurately. For example, in a situation in which some shorting bar circuits 2 are not cut off in the laser cutting areas 20, but a part of the detecting image corresponding to the shorting bar circuit 2 that is not cut off is black due to bad reflecting effect by the shorting bar circuit 2, when the detecting unit 7 judges based on the detecting image, it will be determined that no shorting bar circuit 2 remains in the area, that is, it is mistakenly detected that the shorting bar circuit 2 is cut off, thus resulting in missed detection.

DETAILED DESCRIPTION OF THE EMBODIMENTS

To make those skilled in the art better understand the technical solutions of the present invention, a detecting apparatus and a detecting method provided by the present invention will be described in detail below in combination with the accompanying drawings.

FIG. 3 is a schematic diagram of a structure of a detecting apparatus provided by Embodiment 1 of the present invention, and FIG. 4 is a schematic diagram of a detecting image generated by the image generating unit in the detecting apparatus shown in FIG. 3. As shown in FIGS. 3 and 4, the detecting apparatus is configured to detect whether a shorting bar circuit 2 in a panel 1 is cut off, and the detecting apparatus comprises: a base 3, a light source module, an image generating unit 6 and a detecting unit 7. Positioning pillars 4 for supporting a lower surface of the panel 1 and positioning the panel 1 are provided on the base 3, and the image generating unit 6 is arranged above the panel 1 and connected to the detecting unit 7. The light source module is configured to generate detecting light 5 and cause the detecting light 5 to irradiate towards the image generating unit 6 after passing through the area of the shorting bar circuit 2 in the panel 1. In the present embodiment, the light source module comprises a second surface light source 10 provided on the base 3, and the detecting light 5 generated by the second surface light source 10 irradiates towards the image generating unit 6 after passing through the area of the shorting bar circuit 2 in the panel 1. Specifically, the detecting light 5 irradiates towards the upper surface of the panel 1 from the lower surface of the panel 1, and thus passing through the area of the shorting bar circuit 2 in the panel 1. It should be noted that, the second surface light source 10 may comprises a plurality of LED lamps. The image generating unit 6 is configured to receive the detecting light 5 irradiating thereon (i.e, the detecting light 5 transmitted out from the upper surface of the panel 1), and generate a detecting image of the area of the shorting bar circuit 2. The detecting unit 7 is configured to detect whether the shorting bar circuit 2 in the panel 1 is cut off based on the detecting image.

The working principle of the detecting apparatus provided by the present embodiment is as follow.

At first, the light source module generates detecting light 5, and causes the detecting light 5 to irradiate towards the image generating unit 6 after passing through the area of the shorting bar circuit 2 in the panel 1. At this point, at a part of the area of the shorting bar circuit 2 where a part of the shorting bar circuit 2 remains, the detecting light 5 will be blocked by the part of the shorting bar circuit 2, while at a part of the area of the shorting bar circuit 2 where no shorting bar circuit 2 remains, the detecting light 5 will be transmitted into the image generating unit 6.

Then, the image generating unit 6 generates a detecting image of the area of the shorting bar circuit 2 in the panel 1 based on the received transmitted detecting light 5. In the detecting image, it is black at a position 8 corresponding to a part of the panel 1 where the shorting bar circuit 2 remains, while it is white at a position 9 (and position 20) corresponding to a part of the panel 1 where no shorting bar circuit 2 remains.

At last, the detecting unit 7 can detect whether the shorting bar circuit 2 is cut off according to the detecting image.

As shown in FIG. 5, the detecting unit 7 may comprise: a color determining module 11 configured to determine whether it is white at a position in the detecting image corresponding to a laser cutting area 20, if it is white at the position in the detecting image corresponding to the laser cutting area 20, it is determined that the shorting bar circuit 2 is cut off, if it is black at the position in the detecting image corresponding to the laser cutting area 20, it is determined that the shorting bar circuit 2 is not cut off. Further, the color determining module 11 may comprise: a grayscale calculation sub-module 12 and a grayscale comparison sub-module 13 which are connected to each other. The grayscale calculation sub-module 12 is configured to calculate a grayscale value at the position in the detecting image corresponding to the laser cutting area 20, and the grayscale comparison sub-module 13 is configured to determine whether the grayscale value is larger than a reference grayscale value, if the grayscale comparison sub-module 13 determines that the grayscale value is smaller than or equal to the reference grayscale value, it is determined that it is white at the position in the detecting image corresponding to the laser cutting area 20, if the grayscale comparison sub-module 13 determines that the grayscale value is larger than the reference grayscale value, it is determined that it is black at the position in the detecting image corresponding to the laser cutting area 20.

It should be additionally noted that, in the present embodiment, the base 3 may be covered by LEDs lamps, so as to meet requirements of detections of panels 1 with different sizes and shorting bar circuits 2 at different positions of the panel 1.

Compared to the prior art, the detecting apparatus provided by the present embodiment comprises the light source module, the detecting light 5 generated by the light source module irradiates towards the image generating unit 6 after passing through the area of the shorting bar circuit 2 in the panel 1 (i.e., passing through the panel 1), and the image generating unit 6 then generates a detecting image. As the detecting light 5 passing through the area of the shorting bar circuit 2 in the panel 1 lasts for a relatively long time and is of relatively high brightness, the detecting image generated by the image generating unit 6 is relatively clear, that is, the generated detecting image can reflect the actual situation of the shorting bar circuit 2 more clearly and accurately. In this case, the detecting result obtained by the detecting unit 7 based on the detecting image will be relatively accurate.

FIG. 6 is a schematic diagram of a structure of a detecting apparatus provided by Embodiment 2 of the present invention. As shown in FIG. 6, the present embodiment differs from the above Embodiment 1 in that, the light source module in the present embodiment comprises: a third surface light source 14 provided below the base 3, and the base 3 is a transparent base. The third surface light source 14 is configured to generate detecting light 5, and the detecting light 5 generated by the third surface light source 14 irradiates towards the image generating unit 6 after sequentially passing through the base 3, the lower surface and the upper surface of the panel 1.

In the present embodiment, the third surface light source 14 may comprise a plurality of LED lamps and a supporting plate for supporting the LED lamps.

Compared with the above Embodiment 1, the third surface light source 14 in the present embodiment is provided below the base 3, and the base 3 is provided as a transparent base 3, which can effectively avoid damage caused by contact between the third surface light source 14 and other device(s), thus effectively prolonging lifespan of the third surface light source 14.

FIG. 7 is a schematic diagram of a structure of a detecting apparatus provided by Embodiment 3 of the present invention. As shown in FIG. 7, the present embodiment differs from the above Embodiment 1 and Embodiment 2 in that, the light source module in the present embodiment comprises: a first surface light source 16 provided above the panel 1 and a reflecting mechanism provided below the panel 1. The first surface light source 16 is configured to generate detecting light 5, the detecting light 5 generated by the first surface light source 16 irradiates towards the reflecting mechanism after passing through the panel 1 (specifically, sequentially passing through the upper surface and the lower surface of the panel 1), and the reflecting mechanism is configured to reflect, to the area of the shorting bar circuit 2 in the panel 1, the detecting light 5 irradiating thereon (i.e., the detecting light 5 exiting from the lower surface of the panel 1), so that the detecting light 5 reflected by the reflecting mechanism irradiates towards the image generating unit 6 after passing through the area of the shorting bar circuit 2 in the panel 1 (i.e., sequentially passing through the lower surface and the upper surface of the panel 1). The first surface light source 16 may comprises a plurality of LED lamps.

In the present embodiment, the reflecting mechanism is a layer of reflecting film 17, and the reflecting film 17 is provided on the base 3. Specifically, the reflecting film 17 may be an aluminum film.

In practical manufacturing process, laser cutting of the shorting bar circuit 2 and detection of the cutting effect are performed on the same base 3, while in the process of laser cutting, a part of laser may penetrate the panel 1 and irradiate onto the base 3. Therefore, if an electric device (e.g., the second surface light source 10 in the above Embodiment 1 or the third surface light source 14 in the above Embodiment 2) is provided below the panel 1, the electric device can be easily damaged in the process of laser cutting.

In the present embodiment, by providing the first surface light source 16 above the panel 1 and covering the base 3 with one layer of reflecting film 17, the detecting light 5 can irradiate towards the image generating unit 6 after passing through the area of the shorting bar circuit 2 in the panel 1, without providing an electric device below the panel 1, and thus the above technical problem is effectively solved.

To facilitate adjusting irradiating direction of the detecting light 5, the light source module may further comprises a second adjusting unit 15. The second adjusting unit 15 is provided on the image generating unit 6 and connected to the first surface light source 16, and the second adjusting unit 15 is configured to adjust an irradiating direction of the detecting light 5 generated by the first surface light source 16. With the second adjusting unit 15, the detecting light 5 reflected by the reflecting film 17 can be easily controlled to irradiate towards the area of the shorting bar circuit 2 on the panel 1.

FIG. 8 is a schematic diagram of a structure of a detecting apparatus provided by Embodiment 4 of the present invention. As shown in FIG. 8, the present embodiment differs from the above Embodiment 3 in that, the light source module in the present embodiment comprises: a first surface light source 16, a reflecting mirror 19 and a first adjusting unit 18. The first adjusting unit 18 is provided on the base 3 and connected to the reflecting mirror 19, and the first adjusting unit 18 is configured to adjust a reflecting direction of the reflecting mirror 19.

In the present invention, the second adjusting unit 15 is configured to adjust the irradiating direction of the detecting light 5 generated by the first surface light source 16, so that the detecting light 5 irradiates towards the reflecting mirror 19. The first adjusting unit 18 is configured to adjust the reflecting direction of the reflecting mirror 19, so that the detecting light 5 reflected by the reflecting mirror 19 irradiates towards the area of the shorting bar circuit 2 on the panel 1.

In the present embodiment, the reflecting mirror 19 may be a plane mirror, a concave reflecting mirror or a total reflecting prism. When the reflecting mirror 19 is a concave reflecting mirror, the detecting light 5 can be converged. In this case, the detecting light 5 reflected to the area of the shorting bar circuit 2 by the concave reflecting mirror can have enhanced brightness, accordingly, the detecting image generated by the image generating unit 6 can be clearer, and thus accuracy of the detecting result can be effectively improved.

It should be noted that, the detecting image generated by the image generating unit 6 in the detecting apparatus provided by any one of the above Embodiments 2 to 4 may refer to that shown in FIG. 4, and detailed description thereof is omitted herein.

It should be noted that, in any one of the detecting apparatuses in the above Embodiments 1 to 4, the positions, in the vertical direction, of the image generating unit 6, the detecting unit 7 and the light source module with respect to the panel 1 may be changed, as long as the detecting light 5 emitted from the light source module can irradiate towards the image generating unit 6 after passing through the area of the shorting bar circuit 2 in the panel 1. For example, in FIG. 6, the image generating unit 6 may be provided below the panel 1 (or below the transparent base 3), and the third surface light source 14 may be provided above the panel 1.

The detecting apparatus provided by the embodiments of the present invention comprises: a base, a light source module, an image generating unit and a detecting unit. In the technical solution of the present invention, the light source module generates detecting light and causes the detecting light to irradiate towards the image generating unit after passing through the area of the shorting bar circuit in the panel, and the image generating unit then generates a detecting image. As the detecting light passing through the area of the shorting bar circuit in the panel lasts for a relatively long time and is of relatively high brightness, the detecting image generated by the image generating unit is relatively clear, that is, the detecting image can reflect the actual situation of the shorting bar circuit more clearly and accurately. In this case, the detecting unit can detect more accurately whether the shorting bar circuit in the panel is cut off based on the detecting image.
