Abstract

The present invention relates to a touch sensor having enhanced durability and optical characteristics and a method of manufacturing the same. The method includes the steps of: supplying a touch sensor to an annealing chamber, the touch sensor including a base film and a touch sensor layer formed on the base film; and performing an annealing process on the touch sensor in the annealing chamber, wherein a thickness of a transparent electrode unit constituting the touch sensor layer ranges from about 35 nm to about 150 nm. According to the present invention, by optimizing the thickness and annealing conditions of the transparent electrode unit that affect the durability and optical characteristics of the touch sensor, flexibility and durability of the touch sensor can be simultaneously enhanced while minimizing degradation of the optical characteristics of the touch sensor.

Description

technical field [0001] The present invention relates to a touch sensor with improved durability and optical characteristics. More particularly, the present invention relates to a touch sensor and a method of manufacturing the same, which can simultaneously improve the flexibility and durability of the touch sensor by optimizing the thickness and annealing conditions of transparent electrode units that affect the durability and optical characteristics of the touch sensor, and enable Degradation of optical characteristics of the touch sensor is minimized. Background technique [0002] In general, a touch sensor is a device configured to detect a touch point that responds to a touch when a user touches an image displayed on a screen with a finger or a stylus. [0003] Touch sensors are usually manufactured in such a way as to cover a display device such as a liquid crystal display (LCD) or an organic light emitting diode (OLED). [0004] In recent years, research on flexible ...
