Next, a display device according to another embodiment of the present invention will be described.

6 is a completed perspective view showing a display device according to another embodiment of the present invention, FIG. 7 is an enlarged perspective view showing a portion 'P2' of FIG. 1, and FIG. 8 is cut along the line BB of FIG. 6. 9 is an enlarged cross-sectional view of a portion 'S2' of FIG. 8.

6 to 9, the display device 200 according to another embodiment of the present invention may include a display panel 110, a design film 220, a light source unit 230, and an adhesive 140. have. Here, 'L' shown in the drawing is a design that is displayed as light is emitted to the outside during a standby time when the display apparatus 200 is turned on or off, and may not be displayed at a time other than the standby time. In addition, the 'L' is a design displayed as light is emitted to the outside for a predetermined time after the power of the display apparatus 200 is turned on, so that the mood function of the display apparatus 200 may be implemented. .

The display apparatus 200 according to another exemplary embodiment of the present invention has the same configuration as that of the design film 220 and the light source unit 230, which is different from the display apparatus 100 according to the exemplary embodiment of the present invention. Play a role. Accordingly, duplicate description of the same configuration will be omitted, and the configuration of the design film 220 and the light source unit 230 will be mainly described.

The design film 220 is formed to include the transparent substrate 121, the ink layer 222, and the light emitting pattern 223. The design film 220 is attached to one surface of the display panel 110 so that a part of the external design of the display apparatus 200 may be formed. To form.

Since the transparent substrate 121 has been sufficiently described above, a detailed description thereof will be omitted.

The ink layer 222 is similar to the ink layer 122. However, the ink layer 222 is formed to include the first ink layer 222a and the second ink layer 222b having a lower saturation than the first ink layer 222a, thereby forming the second ink layer 222b. Some areas may be the light emission pattern 223.

Specifically, the first ink layer 222a is a dark opaque ink (for example, a peripheral region of the region where the light emission pattern 223 is to be formed) of the second surface 121b of the transparent substrate 121. For example, dark black ink). The first ink layer 222a blocks the light generated from the light source 230 without transmitting it.

The second ink layer 222b is formed of light opaque ink (for example, light black ink) on the second surface 121b of the transparent substrate 121 and the first ink layer 222a. The second ink layer 222b transmits light generated from the light source unit 230.

The light emission pattern 223 is a region of the second ink layer 222b that contacts the second surface 121b of the transparent substrate 121. The light emission pattern 223 is formed of a second ink layer 222b formed of light opaque ink, and receives light generated from the light source 230 to be emitted outside the first surface 121a of the transparent substrate 121. do. Accordingly, the light emission pattern 223 may display the 'L' design of FIG. 6 during a standby time when the display apparatus 200 is turned on or off, and after the display apparatus 200 is turned on For some time, the 'L' design of FIG. 6 may be displayed. In this case, the light emission pattern 223 must be formed in a region corresponding to the 'L' design of the second surface 121b of the transparent substrate 121 in order to display the 'L' design on the display apparatus 200. do. Meanwhile, although the 'L' design is shown as a picture design in FIG. 6, other designs such as letters and numbers are possible, and thus the present invention is not limited to the L 'design.

As described above, the light emission pattern 223 may be formed using the first ink layer 222a formed of the dark opaque ink and the second ink layer 222b formed of the light opaque ink. Both the first ink layer 222a and the second ink layer 222b may be formed of dark opaque ink, but the second ink layer 222b may be formed to have a thickness thinner than that of the first ink layer 222b. In this case, the light emission pattern 223 receives the light generated from the light source unit 230 using the second ink layer 222b having a thin thickness and emits the light to the outside of the first surface 121a of the transparent substrate 121. Thus, the 'L' design of FIG. 6 may be displayed during a standby time when the display apparatus 200 is turned on or off, and the 'L' of FIG. 6 may be displayed for a predetermined time after the power of the display apparatus 200 is turned on. 'The design can be displayed. This is because even if the second ink layer 223b is formed of a dark opaque ink, light can be transmitted to some extent if it is thinly formed.

The light source unit 230 is similar to the light source unit 130. However, the light source 230 is installed on one surface of the display panel 110 facing the ink layer 222, and generates light to supply light to the light emission pattern 223. The light source 230 may include a light source 231 and an exterior layer 232 surrounding the light source 231. Here, the light source 231 may be formed by coating a light emitting material for generating light by a power source (not shown) to be a thin coating layer. The light source 231 may be formed of, for example, a light emitting material for a light emitting diode (LED) or a light emitting material for an organic light emitting diode (OLED), but the present invention is not limited thereto. The light source 231 may be electrically connected to a power source (not shown) installed on the other surface of the display panel 110 through a connection means such as a flexible printed circuit board (FPCB).

As described above, the display apparatus 200 according to another embodiment of the present invention forms the light emitting pattern 223 using the second ink layer 222b formed of the light opaque ink on the design film 220, thereby providing a power source. The light of the desired design can be emitted to the outside during the waiting time on or off or for a certain time after the power on. Accordingly, the display apparatus 200 according to another embodiment of the present invention may allow the user to recognize that the power on or off operation is being performed, or may implement a mood function after the power is turned on.

The design film 320 is similar to the design film 220. However, the design film 320 further includes a light emitting pattern 123 of the design film 120 shown in FIG. 5. Since the design film 320 includes not only the light emission pattern 223 but also the light emission pattern 123, the design film 320 receives the light generated from the light source unit 220 and is external to the first surface 121a of the transparent substrate 121. It is possible to further increase the efficiency of the discharge.

As described above, the display apparatus 300 according to another embodiment of the present invention includes a design film 320 including the light emission pattern 223 as well as the light emission pattern 223, thereby turning on or off the power.
