Abstract
An embedded touch panel and a manufacturing method are provided. Touch drive lines of a touch panel adopt a segmented structure design so that spacings between the touch drive lines and the touch sense lines are changed, and changes of the spacings cause changes of capacitance values between the touch drive lines and the touch sense lines. Through detecting an amount of change of the capacitance value, a magnitude of a user's pressing force is determined to make a further judgment as to whether it is a light press or a heavy press so as to retrieve a corresponding instruction. Only four masks are needed to fabricate the structure of the touch circuit lines. The manufacturing process is relatively simple to reduce the manufacturing cost.
