Abstract: The present disclosure relates to a technical field of display panel manufacture, in particular relates to a film material attaching method and a film material attachment device. The method includes: putting a film material on a backing material on a base table, a side of the film material with an adhesive layer facing towards the backing material to be attached and aligning the film material and the backing material; pressing a corner of the film material on the base table by an attaching roller which will roll along a preset direction, wherein an included angle between the preset direction and either side of the corner of the film material is smaller than an angle of the corner of the film material. By attaching the film material using an attaching roller at an angle with respect to the film material, instead of attaching the film material directly at one side by an attaching roller in traditional attaching process, the present disclosure can solve the problem that a linear bubble is easily to be generated at the edge of the film material in the attaching process.

Abstract: An in-cell touch screen and display device, which multiplex the common electrode layer as self-capacitance electrodes using self-capacitance principle, modify the pattern of the common electrode layer to segment it into a plurality of independent self-capacitance electrodes, and add on the array substrate touch control data lines that connect the respective self-capacitance electrodes to the touch control detection chip. Orthographic projections of the respective touch control data lines on the array substrate are all within areas where gaps between the pixel areas reside, so as to not affect the aperture ratio of pixel. Embodiments of the present invention modify the structure of the common electrode layer to segment it into self-capacitance electrodes, thus avoiding additional processes of manufacturing an array substrate, saving the production cost, and improving the production efficiency.
