KR-102964101-B1 - DISPLAY DEVICE

Abstract

The present invention relates to a display device capable of preventing the step difference of the wiring of a digitizer layer for detecting touch input using an electronic pen from being visible on the front of the display device. A display device according to one embodiment comprises a display panel for displaying an image on the front, a digitizer layer disposed on the back surface of the display panel and forming a magnetic field by first electrode patterns and second electrode patterns, a shielding member disposed on the back surface of the digitizer layer for shielding the magnetic field of the digitizer layer, and a rigid member disposed between the display panel and the shielding member.

Description

Display Device The present invention relates to a display device. As the information society develops, the demand for display devices to show images is increasing in various forms. For example, display devices are being applied to a wide range of electronic devices, such as smartphones, digital cameras, laptop computers, navigation systems, and smart televisions. Recently, in order to enhance the portability of display devices while simultaneously providing a large display screen, bendable display devices or foldable display devices with a display area that can be bent or folded are being released. Furthermore, recent display devices support touch input using an electronic pen (e.g., a stylus pen) in addition to touch input using a part of the user's body (e.g., a finger). By utilizing touch input with an electronic pen, the display device can detect touch input more precisely than when using only touch input with a part of the user's body. However, due to the step height difference of the wiring in the digitizer layer for detecting touch input using an electronic pen, the protective film placed on the digitizer layer may have an uneven, bumpy shape. Consequently, when the display device is not displaying an image and high-intensity light is shone onto the front of the display device, the bumpy shape of the protective film caused by the step height difference of the digitizer layer wiring can be visible to the user on the front of the display device.
