Abstract

The invention discloses a touch control graphics structure for an embedded capacitive touch screen. The touch control graphics structure comprises driving lines insulated with each other and in the first direction, and a plurality of sensing lines insulated with each other and in the second direction, wherein the first direction is vertical to the second direction; the driving lines are insulated with the sensing lines; and at least a part of opposite sides of the driving lines and the sensing lines are in an embedded structure. According to the invention, the embedded structure is formed between the driving lines and the sensing lines of the touch control graphics structure for the embedded capacitive touch screen, as a result, the lengths of the opposite edges of the driving lines and the sensing lines are increased, and further, mutual capacity effect of the driving lines and the sensing lines is enhanced, and sensitivity of touch control is improved.

Description

technical field [0001] The invention relates to the field of touch control, in particular to an embedded capacitive touch graphic structure. Background technique [0002] Since the world's first resistive touch screen appeared in 1974, touch technology has developed rapidly, and the industry has produced various types of products such as capacitive, resistive, infrared and acoustic wave. Among them, the capacitive touch screen has become the mainstream product in the current market due to its advantages of precise and sensitive positioning, good touch feel, long service life and support for multi-touch. [0003] Capacitive touch screens are divided into self-capacitive and mutual-capacitive. Since the mutual capacitive touch screen can realize multi-touch, the mutual capacitive touch screen has become the mainstream and future development trend in the capacitive touch screen market. [0004] At present, most of the mutual capacitive touch screens adopt an external structur...
