Field
The present disclosure relates to a display device and a method of manufacturing the same and more particularly, to a display device including an in-cell touch sensor.
Description of the Related Art
Conventionally, a touch screen panel has been manufactured separately and then bonded to a display panel when implementing a display device capable of recognizing a user's touch. That is, a touch electrode has been formed separately using a glass substrate, a plastic substrate, a film or a sheet as a supporting member. Then, the supporting member on which the touch electrode is formed has been bonded to a display panel with an adhesive sheet or an adhesive to implement a touch function.
In recent years, the conventional technology has been replaced with a technology of forming a touch sensor in a display panel according to the trend toward lightweight and slim display devices. That is, a touch electrode is deposited on a display panel using the display panel as a supporting member without a separate supporting member, or a touch sensor is disposed within the display panel. Thus, a display device including the display panel with a touch function has been implemented.
When a touch sensor is formed within a display panel, the touch sensor is physically very close to various components of the display panel. Thus, the interference between the touch sensor and the other components needs to be considered. In order for the touch sensor of the display device to recognize a user's touch more precisely, it may be necessary to consider factors that cause unintended interference in the touch sensor. However, due to the industry trend toward ultra-slim display panels, unintended interference has not been addressed to satisfaction.
Further, two types of touch sensors are embedded together in the display device to recognize a user's touch to provide the user with various user-interfaces (UI) and user-experiences (UX) while displaying an image. In order for such multiple touch sensors to recognize a user's touch harmoniously without interfering with each other, it may be necessary to optimize the positional relationship between the two types of touch sensors.
