Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a liquid crystal display panel structure and a manufacturing method thereof. Background technique [0002] At present, with the development of science and technology, thin film transistor liquid crystal display (TFT-LCD) has become the mainstream product of information display due to its advantages of excellent display quality and reasonable price. Optimization. [0003] The liquid crystal display panel consists of upper and lower glass substrates: the upper glass substrate is a color filter substrate, which carries a color filter film (CF, Color Filter) displaying RGB three primary colors; the lower glass substrate is an array substrate, which is an array of TFT control switches . In the production process of liquid crystal display panels, the sealing of the array substrate and the color filter substrate and the current conduction between the two substrates are...

AI Technical Summary

Problems solved by technology

In the process of realizing the above-mentioned solution 1, the inventors found that there are at least the following problems in the prior art: since the conductive glue is point-connected, the upper and lower substrates can only achieve electrode conduction through the point where the conductive glue is located, which is not conducive to the connection between charges. Moreover, since the conductive adhesive occupies a certain position, the fluctuation range of the position of the sealing glue is reduced, and the defect rate of the product increases to a certain extent; in addition, the metal at the position of the conductive adhesive is easily corroded

[0007] In the process of realizing the above two solutions, the inventor found at least the following problems in the prior art: the glass spacer is mixed in the frame sealant, mainly to support the upper and lower glass substrates, and it must be evenly distributed with the sealant. The frame glue is coated on the glass substrate, once the distribution is uneven, it will cause some glass spacers to gather together

In the whole process, it is easy to cause the glass spacer to be unevenly distributed in the sealant and gather together, resulting in uneven thickness of the surrounding box of the LCD panel, resulting in defects, and it is impossible to maintain the upper and lower glass substrates. Appropriate gaps between them will cause uneven distribution of the electric field, resulting in partial or overall unevenness of the screen, which will affect the display quality of the product; in addition, the conductive balls in the second scheme will also appear in the uneven distribution of the sealing glue , affecting the conduction of current between the two substrates, which in turn affects the display quality of the product
