The broadcast reception unit 110 may include a tuner unit 111 and a demodulation unit 112.

Meanwhile, unlike the drawing, the display device 100 includes only the external device interface unit 171 and the network interface unit 172 among the broadcast receiver 110, the external device interface unit 171, and the network interface unit 172. It is also possible to do so. That is, the display device 100 may not include the broadcast reception unit 110.

The tuner unit 111 may select a broadcast signal corresponding to a channel selected by the user or all previously stored channels among broadcast signals received through an antenna (not shown) or a cable (not shown). The tuner unit 111 can convert the selected broadcast signal into an intermediate frequency signal or a baseband video or audio signal.

For example, if the selected broadcast signal is a digital broadcast signal, the tuner unit 111 may convert it into a digital IF signal (DIF), and if the selected broadcast signal is an analog broadcast signal, it may be converted into an analog baseband video or audio signal (CVBS/SIF). That is, the tuner unit 111 can process digital broadcasting signals or analog broadcasting signals. The analog base band video or audio signal (CVBS/SIF) output from the tuner unit 111 may be directly input to the control unit 180.

Meanwhile, the tuner unit 111 can sequentially select broadcast signals of all broadcast channels stored through a channel memory function among received broadcast signals and convert them into intermediate frequency signals or baseband video or audio signals.

In addition, the content, image quality, size, etc. of the image provided to the display module 180 can be controlled differently depending on the viewer or surrounding illumination detected by the sensing unit to provide an optimal viewing environment. As smart TVs advance, the number of functions mounted on the TV increases and the number of sensing units 20 also increases.

The input unit 130 may be provided on one side of the main body of the display device 100. For example, the input unit 130 may include a touch pad, physical buttons, etc. The input unit 130 can receive various user commands related to the operation of the display device 100 and transmit control signals corresponding to the input commands to the control unit 180.

Recently, as the size of the bezel of the display device 100 has become smaller, the number of display devices 100 in which the input unit 130 in the form of a physical button exposed to the outside has been minimized has increased. Instead, a minimal physical button is located on the back or side, and user input can be received through the remote control device 200 through a touchpad or a user input interface unit 173, which will be described later.

The storage unit 140 may store programs for processing and controlling each signal in the control unit 180, or may store processed video, audio, or data signals.

Programs stored in the storage unit 140 are not particularly limited as long as they can be executed by the control unit 180. The storage unit 140 may perform a function for temporarily storing video, voice, or data signals received from an external device through the external device interface unit 171. The storage unit 140 can store information about a certain broadcast channel through a channel memory function such as a channel map.

Although FIG. 1 shows an embodiment in which the storage unit 140 is provided separately from the control unit 180, the scope of the present invention is not limited thereto, and the storage unit 140 may be included in the control unit 180.

The storage unit 140 includes volatile memory (e.g., DRAM, SRAM, SDRAM, etc.), non-volatile memory (e.g., flash memory, hard disk drive (HDD), and solid state drive (Solid- It may include at least one of state drive (SSD), etc.).

Recently, the display device 100 is a display module 150 that can be bent, such as LED (Light Emitting Diodes) or OLED (Organic Light Emitting Diodes), to implement a curved screen beyond a flat surface. can be used.

LCDs, which were mainly used in the past, received light through a backlight unit because it was difficult for the LCD to emit light on its own. The backlight unit is a device that uniformly supplies the light source and the light supplied from the light source to the liquid crystal located on the front. As the backlight unit became increasingly thinner, it was possible to implement a thin LCD, but it is difficult to implement the backlight unit using a flexible material, and when the backlight unit is bent, it is difficult to supply light uniformly to the liquid crystal, causing a problem in that the brightness of the screen changes.

On the other hand, in the case of LED or OLED, each element that makes up the pixel emits light on its own, so it can be implemented in a curved manner without using a backlight unit. In addition, since each element emits its own light, even if the positional relationship with neighboring elements changes, its own brightness is not affected, so the flexible display module 150 can be implemented using LED or OLED.

OLED (Organic Light Emitting Diode) panels appeared in earnest in the mid-2010s and are quickly replacing LCD in the small and medium-sized display market. OLED is a display made using a self-luminous phenomenon that emits light when a current flows through a fluorescent organic compound. The picture quality response speed is faster than that of LCD, so there is almost no afterimage when displaying a video.

OLED uses three types of phosphor organic compounds, including red, green, and blue, which have a self-luminous function. Electrons and positively charged particles injected from the cathode and anode are used to emit light. Since it is a light-emitting display product that utilizes the phenomenon of self-emitting light by combining within organic materials, there is no need for a backlight (halo device) that reduces color.

The LED (Light Emitting Diode) panel is a technology that uses one LED element as one pixel, and the size of the LED element can be reduced compared to the prior art, making it possible to implement a flexible display module 150. Previously, devices called LED TVs used LEDs as a light source for the backlight unit that supplied light to the LCD, but the LEDs themselves did not constitute a screen.

The display module includes a display panel, a coupling magnet located on the back of the display panel, a first power supply, and a first signal module. The display panel may include a plurality of pixels (R, G, B). A plurality of pixels (R, G, B) may be formed in each area where a plurality of data lines and a plurality of gate lines intersect. A plurality of pixels (R, G, B) may be placed or arranged in a matrix form.
