Embodiment approach

[0152] According to some exemplary embodiments, the second connection electrode BE2 may be located on the second buffer film BF2, so that the sensing electrode RE may pass through the second connection electrode BE2 and the next sensing electrode RE in the first direction (x-axis direction). Electric connection.

[0153] Each of the first connection electrode BE1 and the second connection electrode BE2 can be made of a stacked structure of aluminum and titanium (Ti / Al / Ti), a stacked structure of aluminum and ITO (ITO / Al / ITO), APC alloy, and APC alloy and The ITO stack structure (ITO / APC / ITO) is made, but not limited to this.

[0154] The sensor insulating layer TINS ​​is formed on the driving electrode TE, the sensing electrode RE, and the second connection electrode BE2. The sensor insulating layer TINS ​​may be formed of an inorganic layer (for example, a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer)...

Abstract

The application relates to a sensor unit and a method for detecting cracks. The sensor includes: a hole; a sensing area formed around the hole, wherein at least one sensor is in the sensing area; anda crack detector configured to output a first crack signal if a comparison value obtained by comparing a detected value from the at least one sensor with a reference value exceeds an error range.

Description

[0001] Cross references to related applications [0002] This application claims the priority and rights of Korean patent application No. 10-2019-0023910 filed on February 28, 2019, and the entire content of the Korean patent application is incorporated herein by reference. Technical field [0003] Aspects of some exemplary embodiments of the present disclosure relate to a sensor unit, a display device including the sensor unit, and a method of detecting a crack using the sensor unit. Background technique [0004] With the development of the information society, various demands for display devices continue to increase. Accordingly, various types of display devices may be utilized, such as a liquid crystal display (LCD) device, a plasma display panel (PDP) device, and an organic light emitting display (OLED) device. [0005] In order to expand the display area, the display device may include a hole in the display area in which a sensor such as a camera device is positioned. [0006] Du...
