Abstract

The invention discloses an implement method of ON CELL. The implement method comprises a liquid crystal display, a flexible printed circuit (FPC) and a conductive thin film with a touch function. The manufacture method of the conductive thin film with the touch function includes the following steps: an indium tin diode (ITO) layer is coated on the thin film in a vacuum sputtering mode, coating photoresist, exposing the photoresist, developing and hardening the photoresist, etching the ITO thin film layer, eliminating the photoresist to form an ITO electrode and manufacture the conductive thin film with the touch function; pasting the FPC on the conductive thin film with the touch function through the heat press method, then pasting the pasted conductive thin film with the touch function on the liquid crystal display, and attaching one side face of the FPC to one side face of the liquid crystal display. The conductive thin film with the touch function is adopted on the liquid crystal display, so the integration of the liquid crystal display and touch screen components is realized and the display function can not be affected. Products are enabled to be lighter and thinner, and material cost and manual cost are reduced.

Description

technical field [0001] The invention relates to the field of electronic components, in particular to an ONCELL implementation method. Background technique [0002] ONCELL refers to the method of embedding the touch panel function between the color filter substrate and the polarizing plate. The original technology is to combine the LCD screen and the touch screen panel components together; paste the FPC on the Sensor by hot pressing, then paste the cover plate and the hot-pressed Sensor together with optical transparent glue, and finally attach the LCD screen and The pasted parts are assembled together. Disadvantages of this method: the overall product is heavy and thick, and the touch screen panel material and production costs are high. Contents of the invention [0003] The purpose of the present invention is to provide a realization method of ONCELL, which uses a thin film with touch function on the liquid crystal screen to replace the traditional external capacitive t...
