The disclosure relates to a display device having an improved structure of a frame on which a display panel is mounted in a bezel-less display device.
In general, a display device is a device that displays a screen, such as a monitor, a television (TV), or the like. Display devices use self-emissive display panels, such as organic light-emitting diodes (OLEDs), and non-emissive display panels, such as liquid crystal display (LCD) panels.
Recently, bezel-less display devices have become more popular due to their fuller screen and simpler design. A bezel-less display device may include a display panel that displays an image and a frame on which the display panel is mounted. When the display panel is seated on the frame, the frame may form the appearance of a four-sided border of the bezel-less display device.
The bottom of the display panel is connected to a chip-on-film (COF) that transmits a drive signal from a drive printed circuit board (PCB) to the display panel. The COF is required to be folded and organized on the back of the display panel so that it is not visible from the exterior of the product. To fold and organize the COF to the back of the display panel, first the frame at the bottom of the display panel needs to be separated from the display panel and spread away, then the COF needs to be inserted into a space between the display panel and the frame, and finally the COF needs to be folded to the back of the display panel, resulting in inconvenience. In addition, the COF may be damaged in the process of organizing the COF.
To organize the COF as described above, the frame assembled on the bottom of the display panel is assembled with a screw, so that after the COF is organized, the frame is assembled on the bottom of the display panel. However, since the frame is assembled on the bottom of the display panel by screws, a separate bracket for assembling the screws is required to be pre-assembled to the frame assembled on the bottom of the display panel. In addition, since the frame is assembled with screws to the bottom of the display panel, the screws may be exposed to the outside.
Provided is a display device including a frame on which a display panel is seated in a bezel-less display device is divided into a first frame forming an upper, left, and right border appearance of the display panel, and a second frame forming a lower border appearance of the display panel.
Further, provided is a display device in which a second frame forming a lower border appearance of a display panel is hooked to a lower portion of the display panel.
