Optical film OCF - T

THERMOPLASTIC OPTICAL CLEAR FILM is the best choice for the combination of touch screen and display screen. Applied to the transparent optical element and TP/LCM all kinds of size, all in all the laminating process is superior to the OCA index optical cellophane tape, adopt the products of the OCF, the indicators products meet and exceed OCA glue application products, for customers to solve the important issues of the finished product defective rate is high, many times to improve the strength of panel, a number of factors lead to the production cost greatly reduced. It is an excellent solution in TP/LCM field.

The OCF film has been used in touch screen production for more than 3 years, and has been used by several manufacturers to meet the technical requirements. The applied bonding process has become mature through continuous improvement of supporting equipment. The use of OCF film will bring high quality and economic products to customers.

8prominent characteristics
  • 01
    Excellent optical performance, over 96% transmittance, non - corrosive to ITO film.
  • 02
    The OCF film has the function of explosion-proof film. Its tensile strength is much better than that of OCA.
  • 03
    It can be applied to all kinds of materials with a wide range of applicability.
  • 04
    Senders ability strong, easy to adjust, the thickness of the diaphragm Μ Μ 100 M to 200 M, diaphragm simple easy to die cutting processing.
  • 05
    Applicable products have wide range of specifications and sizes, no size boundary applies to all kinds of products, from watches to color televisions, and all sizes fit the screen.
  • 06
    The touch screen fully laminating process using OCF film is simple. Compared with the OCA adhesive process route, the short operation is simple and convenient, the processing cycle is short, and the batch can be continuously produced.
  • 07
    Compared with the cost of OCA adhesive equipment, process supporting equipment is greatly reduced, with simple operation and low maintenance cost.
  • 08
    The yield of primary products is more than 95% using OCF film. The defective products can be remanufactured on site before curing without loss, and the production cost can be greatly reduced.

Corollary Equipment
Vacuum plate bonding machine ky-42zk
This equipment is the fitting between the glass SENSOR of projective touch screen and the glass COVER LENS, and the full bonding between the touch screen and tft-lcm. The bonding medium is OCF solid optical adhesive, which is easy to operate, accurate and simple to position, high efficiency, stable quality and stable operation.
Features
        

The table has a high-precision platform

The vacuum is made of the German lebo high vacuum pump, and the negative pressure is high and can be adjusted, so the vacuum time is as short as 5-15 seconds.

Large cylinder is used up and down to make the cavity compacted tightly and the vacuum chamber is sealed to ensure high vacuum.

When the upper plate is heated, the temperature is uniform, making OCF soft under the heat and controlling the bonding bubbles and spacing.

Controlled by PLC and touch screen, stable operation and simple operation.

Cylinder lock cover plate, easy to operate.

Using air cylinder down pressure, precision pressure valve regulation, balance strength.

Using air cylinder down pressure, precision pressure valve regulation, balance strength.

Use special material, not easy to deform.

Using electrophoretic aluminum profile, beautiful appearance.
