Description

Easy to detect panel structure

This creation is related to a panel field, in particular a panel structure that facilitates optical inspection of the quality of the adhesive bond.

With the development of optical technology, the display has been changed from the traditional display of the image tube to the current electronically driven liquid crystal deflection. The liquid crystal display has a relatively thin overall thickness and a relatively light weight. Referring to FIG. 1A and FIG. 1B , the main structure of the liquid crystal display is to form a liquid crystal panel between the two substrates 7 to form a liquid crystal panel, and the liquid crystal layer is driven by the circuit to change the color between the two substrates 7 . A water-repellent colloid layer 6 (optical glue) is applied for bonding. In the process of fabricating the liquid crystal panel, after the two substrates 7 are attached, the condition of the waterproof colloid layer 6 is checked through the optical instrument 5. Generally, the items to be inspected include the width, thickness and uniformity of the waterproof colloid layer 6, and the width is too In a short time, it may cause damage to liquid or dirt running into the two substrates 7 in the subsequent process. The same glue layer such as unevenness (such as bubbles 61 or voids) may cause the above situation, resulting in the above situation. The panel is damaged in subsequent processes and becomes a defective product. When the optical instrument 5 inspects the waterproof colloid layer 6 of the panel, the thickness of the waterproof colloid layer 6 is only 3.5 μm to 5 μm, even if the water-repellent colloid layer 6 of various colors is close to colorless at this thickness (3.5 μm to 5 μm). Light), the image of the inspection area is enlarged by the optical instrument 5, but the contrast between the two parts of the waterproof colloid and the non-waterproof colloid (bubble 61) is not obvious, whether through computer image comparison or human eye judgment, It is very easy to generate erroneous judgments and prolong the overall working time, resulting in many problems of increased production costs and low yield. Therefore, how to solve the above problems and deficiencies, that is, the creators of the case and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

In order to improve the above problems, the main purpose of this creation is to provide a panel structure with obvious contrast in color detection. Another main object of the present work is to provide a panel structure using a water-repellent colloid having photoreactive properties. In order to achieve the above object, the present invention provides a panel structure for facilitating inspection, comprising: a first substrate having a first surface; at least one second substrate having a second surface, the first and second sides correspondingly covering; And at least one fluorescent water-repellent gel layer is filled between the first and second substrates. In one embodiment, the first substrate, the second substrate, and the fluorescent water-repellent gel layer collectively define a sealed space, and a circuit layer is disposed in the sealed space. In one embodiment, the phosphor water-repellent gel layer has a width and a height, the width being 600 to 1450 times the height. In one embodiment, the width of the phosphor water repellent layer is 3 millimeters (mm) and the height is 5 micrometers (μm). In one embodiment, the width of the phosphor water repellent layer is 5 millimeters (mm) and the height is 3.5 micrometers (μm). In one embodiment, the phosphor water repellent layer is composed of a mixture of a fluorescent agent and an optical adhesive (Optical Clear Adhesive. OCA). In one embodiment, the phosphor water repellent layer is applied to the first and second sides of the first and second substrates near the edge.

The above object of the present invention, as well as its structural and functional features, will be described in accordance with the preferred embodiments of the drawings. Please refer to FIG. 2A, FIG. 2B, FIG. 2C and FIG. 2D for an exploded view, a perspective view, a cross-sectional view and a partial schematic view of the second embodiment of the first embodiment. The panel structure of the present invention includes a first a first substrate 1 having a first surface 11 and a second surface 2 having a second surface 21, the first surface and the second surface 11 and 21 Correspondingly, the phosphor waterproofing layer 3 is applied to the first and second faces 11, 21 of the first and second substrates 1, 2 near the edge. The first substrate 1, the second substrate 2 and the fluorescent water-repellent gel layer 3 jointly define a sealed space, and a circuit layer 4 is disposed in the sealed space. The fluorescent water-repellent gel layer 3 has a width W and a height. H, the width W is 600 to 1450 times the height H, and the fluorescent water-repellent gel layer 3 is composed of a mixture of a fluorescent agent and an optical adhesive (Optical Clear Adhesive. OCA). Please refer to Figures 1A, 1B, 2A, 2B, 2C and 2D together. When performing the test, the optical instrument 5 emits light of a specific wavelength (such as ultraviolet light or X-ray) to excite the fluorescent water-repellent gel layer 3 The fluorescent agent emits fluorescence, and then the detection is performed in this state (the image of the bonding place is enlarged by the optical instrument 5, and the image comparison or the human eye judgment is selected by the computer), because the fluorescent waterproof colloid layer 3 is specified. The light of the wavelength is excited and brightened, and the color difference of the portion filled with the fluorescent waterproof colloid and not filled with the fluorescent waterproof colloid is increased, and the portion having the fluorescent waterproof colloid is bright on the display of the optical instrument 5. Color (the color depends on the material of the phosphor), and the part without the fluorescent gel (such as bubbles or voids) will show a dark color on the display of the optical instrument 5, so that the subsequent detection is performed by the computer. Whether it is compared or judged by the human eye, it can be clearly seen whether the coating of the fluorescent water-repellent gel layer 3 is uniform and full, and when the fluorescent water-repellent gel layer 3 is not excited by light of a specific wavelength, Will be restored to Color or optical adhesive (Optical ClearAdhhesive.OCA) of the base color. The width W and the height L of the fluorescent water-repellent gel layer 3 have a certain ratio, the width W is 600 to 1450 times the height L, and the width W is preferably 3 mm (mm) to 5 mm (mm), and the height. L is the height of the corresponding circuit layer 4 and is approximately 3.5 micrometers (μm) to 5 micrometers (μm). When the width W of the fluorescent water-repellent gel layer 3 is less than 3 mm (mm), the water repellency will be poor in subsequent processing (such as flushing or brewing cleaning liquid), which may cause the cleaning liquid to penetrate into the confined space. The integrity of the circuit layer 4 is destroyed, so that the width W of the preferred fluorescent water-repellent gel layer 3 is not less than 3 millimeters (mm). Please refer to FIG. 3A and FIG. 3B , which are a perspective view and a cross-sectional view of the second embodiment of the present invention. The present embodiment is substantially the same as the first embodiment, so the repeated portions are not described again, and the difference lies in the second substrate 2 . A plurality of first substrates 1 are disposed on the surface of each of the first substrate 1 and the second substrate 2, and the fluorescent water-repellent gel layer 3 is coated on the first surface. The first face 11 of the substrate 1 is near the edge. In this embodiment, the second substrate 21 of the second substrate 2 has a plurality of first substrates 1 , and after detecting the completion of the fluorescent water-repellent gel layer 3 , the portion of the second substrate 2 that does not cover the first substrate 1 is not covered. Cut and make a number of independent panels. In summary, the panel structure of the present invention improves the conventional problem of detecting that the chromatic aberration of the two substrates is not obvious, and improves the inconvenience of detection by means of light excitation, so that the contrast on the detection is more obvious. Easy to detect. The present invention has been described in detail above, but the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited. That is, all changes and modifications made in accordance with the scope of this creation application shall remain covered by the patents of this creation.
