As shown in fig. 1, in the conventional method for detecting the alignment accuracy of the color resistor, by obtaining the distances y1, y2, x1 and x2 between each side of the color resistor 22 and each side of the limiting portion 11, when y1 and y2 are approximately equal or equal, and x1 and x2 are approximately equal or equal, it is determined that the color resistor 22 meets the requirement of the alignment accuracy.

The limiting portion 11 is provided with an opening region (not shown in the figure), the shape of the opening region is square, and the color resistor is positioned in the opening region. Taking the green color resistor as an example, when the green color resistor 22 is manufactured, the previously manufactured red color resistor 21 will block the limiting portion 11 corresponding to the green color resistor 22, so that when the alignment precision of the green color resistor 22 is detected, the image recognition device cannot accurately determine the boundary on the left side of the limiting portion, and further cannot detect the alignment precision of the green color resistor.

Referring to fig. 3 and 4, fig. 3 is a top view of a display panel according to an embodiment of the present disclosure.

As shown in fig. 3, the display panel 100 of the present embodiment includes: a substrate 10, at least one limiting portion 30 and at least one target color resist 42.

The substrate base plate 10 may be a glass base plate or a flexible substrate. The material of the substrate base plate 10 includes one or more of glass, silicon dioxide, polyethylene, polypropylene, polystyrene, polylactic acid, polyethylene terephthalate, polyimide, or polyurethane.

The limiting portion 30 is provided on the substrate base plate 10. With reference to fig. 4, the defining portion 30 includes an opening region 31; the opening region 31 includes a main body sub-region 311 and an auxiliary sub-region 312; in one embodiment, the auxiliary sub-region 312 is located on the upper side of the main body sub-region 311, the left side of the auxiliary sub-region 312 is flush with the left side of the main body sub-region 311, and the width d1 of the auxiliary sub-region 312 is smaller than the width d2 of the main body sub-region 311, the width is parallel to a first direction, such as a horizontal direction in one embodiment.

With reference to fig. 3, the target color resists 42 correspond to the defining portions 30, and the target color resists 42 are located in the opening regions 31 of the corresponding defining portions 30; wherein the target color resistance 42 in the main body sub-region 311 corresponds to the position of the set sub-pixel in the display panel; wherein the color of the sub-pixel is set to be the same sub-pixel as the color of the target color resist 42. In one embodiment, the target color resistor 42 includes a first sub-portion 421 and a second sub-portion 422; the first sub-portion 421 corresponds to the position of the auxiliary sub-area 312; the second sub-portion 422 corresponds to the position of the main body sub-region 311. In one embodiment, the material of the first sub-portion 421 is doped with a light absorbing material, so as to reduce the reflection intensity of the light by the first sub-portion, thereby improving the accuracy of pattern recognition of the first sub-portion. The light absorbing material is not particularly limited. In another embodiment, the material of the second sub-portion 422 is not doped with a light-absorbing material. In another embodiment, the material of the second sub-portion 422 is also doped with a light-absorbing material. In a preferred embodiment, the amount of light absorbing material in the first sub-portion 421 is greater than the amount of light absorbing material in the second sub-portion 422. In another embodiment, the materials of the first sub-portion 421 and the second sub-portion 422 are the same, i.e., the materials of the first sub-portion 421 and the second sub-portion 422 are not doped with the light-absorbing material.

In one embodiment, in order to further improve the accuracy of detecting the color resistance alignment accuracy, the reflection intensity of the limiting portion 30 to the light is greater than the reflection intensity of the target color resistance 42 to the light. In one embodiment, in order to facilitate the identification of the boundary of the defining portion and the boundary of the color resistor, the defining portion 30 is made of a metal material, and the target color resistor 42 is made of a resin. Of course, it is understood that the material of the defining part 30 is not limited to the metal material, and may be other materials as long as the light permeability different from the color resistance is ensured.

In one embodiment, to further improve the accuracy of detecting the color resistance alignment accuracy, the width d1 of the auxiliary sub-region 312 is smaller than 1/3 of the width d2 of the main sub-region 311. For example, the width d1 of the auxiliary sub-region 312 is 1/4 of the width d2 of the main sub-region 311.

In one embodiment, the length L1 of the auxiliary sub-region 312 is greater than 1/3 of the length L2 of the main sub-region 311, so that the left side of the defining part 30 and the left side of the target color resistor 42 can be easily identified, and the accuracy of the precision detection is improved.

In an embodiment, in order to further improve the accuracy of the precision detection, the auxiliary sub-region 312 and the main sub-region 311 are communicated to improve the accuracy of the pattern recognition of the image recognition apparatus.

In one embodiment, in order to further improve the accuracy of the precision detection and simplify the manufacturing process, the auxiliary sub-region 312 is rectangular, and the main sub-region 311 is square. Of course, the shape of the auxiliary sub-area 312 may also be trapezoidal or other shapes. In a preferred embodiment, the opening region 31 has an L-shape.

Because the auxiliary sub-area is added, the auxiliary sub-area 312 is located on the upper side of the main sub-area 311, the left side of the auxiliary sub-area 312 is flush with the left side of the main sub-area 311, and the width of the auxiliary sub-area 312 is smaller than the width of the main sub-area 311, when the manufactured color resistor 41 blocks the limited portion of the target color resistor 42, a difference is formed between the target color resistor and the graph of the limited portion, that is, a left graph identification detection point (shown as an ellipse in fig. 3) is provided, so that the boundary between the left side of the target color resistor corresponding to the auxiliary sub-area and the left side of the limited portion can be obtained through an image identification device, and further the left deviation of the target color resistor is determined, that is, the alignment accuracy of the color resistor can be detected, further, the color deviation or the light leakage phenomenon.

Referring to fig. 5 and 6, fig. 5 is a top view of a display panel according to another embodiment of the present disclosure.

The display panel of the present embodiment is different from the display panel of the previous embodiment in that: the auxiliary sub-region 312 of this embodiment is also located at the lower side of the main sub-region 311.

That is, in conjunction with fig. 5 and 6, the auxiliary sub-region 312 is located at the upper and lower sides of the main body sub-region 311.

Of course, in another embodiment, the auxiliary sub-region 312 may be located at the lower side of the main sub-region 311.

Returning to fig. 5, the target color resistor 42 of the present embodiment includes two first sub-segments 421.

It is understood that in other embodiments, another auxiliary sub-region may be disposed on the left side and/or the right side of the main sub-region 311, that is, the shape of the opening region is not limited to the above shape.

On the basis of the above embodiment, since the auxiliary sub-area 312 of the present embodiment is also located at the lower side of the main sub-area 311, a greater difference is formed between the target color resistance and the pattern of the definition portion, so as to provide a plurality of left pattern recognition detection points (as shown by the ellipses in fig. 5), that is, at this time, the first distance between the left side of the first sub-portion 421 and the left side of the definition portion 30 can be detected at both the upper left corner and the lower left corner.

It is to be understood that fig. 3 to 6 are only given as examples and do not limit the present invention.

s101, acquiring a first distance y1 between the left side of the first sub-part 421 and the left side of the defining part 30;

for example, the defining portion 30 corresponds to the target color resist 42. The light can be irradiated to the display panel, and the target color resist 42 and the limiting portion 30 both reflect the light, but the intensities of the reflected light are different. Therefore, the pattern of the reflected light of the first sub-portion 421 and the pattern of the reflected light of the limiting portion 30 are recognized by the image recognition device, so as to obtain the distance between the left side of the first sub-portion 421 and the left side of the limiting portion 30.

S102, acquiring a second spacing y2 between the right side of the second sub-portion 422 and the right side of the defining portion 30;

s103, obtaining a third distance x1 between the upper side of the second sub-portion 422 and the upper side of the defining portion 30;

s104, obtaining a fourth distance x2 between the lower side of the second sub-portion 422 and the lower side of the defining portion 30;

s105, detecting the alignment accuracy of the target color resistance according to the difference value between the first distance y1 and the second distance y2 and the difference value between the third distance x1 and the fourth distance x 2.

When the difference between the first distance y1 and the second distance y2 is within a preset range, and the difference between the third distance x1 and the fourth distance x2 is also within a preset range, it is determined that the alignment accuracy of the target color resistance meets the process requirement. The preset range is a range close to 0.
