Description

Touch display panel for smart electronic products

technical field

The utility model relates to a touch screen, in particular to a touch display panel for intelligent electronic products.

Background technique

As customers have higher and higher requirements for the display and touch of smart electronic products, after many manufacturers adopt the full bonding technology of touch display panels for smart electronic products, the benefits brought by the thinning of the products not only improve the design of the products, It also simplifies the production process of the supply chain, reduces costs, and no longer needs to purchase touch screens and LCD panels from different manufacturers.

At present, the high cost and low yield of full-lamination display modules make it impossible for many manufacturers to achieve mass production, resulting in only a handful of manufacturers actually applying full-lamination technology. Now the main bonding method is to directly attach the OCA optical adhesive to the upper polarizer of the finished display screen, and then set the touch screen on the OCA optical adhesive of the upper polarizer, so that the touch screen and the finished display screen are bonded together. Processing method The existing polarizers are inconvenient to install and need to be bonded three times, and the cost of OCA optical adhesive is relatively high. The release films on both sides are consumables but occupy a large cost. If the release films on both sides are not matched properly, Cause defective products and increase production costs. At the same time, this processing method will cause the optical glue to overflow into the backlight plate of the finished display screen, so that the backlight plate cannot transmit light normally, resulting in defective products and increasing production costs.

The touch module includes a first plastic film layer and a second plastic film layer having an ITO sensing electrode layer, and the first plastic film layer and the second plastic film layer are bonded by a fourth OCA optical glue;

The display module includes an upper transparent substrate and a lower transparent substrate, and a liquid crystal layer and a TFT film layer are sequentially arranged between the upper transparent substrate and the lower transparent substrate;

The surface of the upper polarizer in contact with the second OCA optical glue is covered with an ink layer, and the ink layer is located at the edge area of the upper polarizer, thereby forming a display area in the central area of the upper polarizer.

The technical scheme further improved in the above-mentioned technical scheme is as follows:

1. In the above scheme, the first plastic film layer is PET film, polypropylene film, polyethylene film or polyvinyl chloride film.

2. In the above scheme, the second plastic film layer is PET film, polypropylene film, polyethylene film or polyvinyl chloride film.

3. In the above solution, the thickness of the first OCA optical glue, the second OCA optical glue and the third OCA optical glue is 0.05~0.25mm.

Due to the application of the above-mentioned technical solutions, the utility model has the following advantages compared with the prior art:

The utility model uses a touch display panel for intelligent electronic products, which realizes that the polarizer, the display screen, and the touch screen are completely pasted together in a seamless manner. The strength is improved by being closely combined with the display screen, which reduces the interference caused by the noise of the display screen to the touch signal, and does not need to consider dust and water vapor; secondly, because the present invention combines the polarizer with OCA optical adhesive The upper polarizer of the semi-finished display screen with a backlight is bonded. After the touch screen and the upper polarizer are bonded, the backlight and the lower polarizer of the display are assembled together, thus preventing the optical glue from spilling into the backlight Inside, it is ensured that the backlight panel can transmit light normally, which will not cause defective products and reduce the production cost.
