Recently, the display module 100 has moved beyond a flat surface to implement a curved screen by using a bendable display 180 such as LED (Light Emitting Diodes) or OLED (Organic Light Emitting Diodes). available.

LCDs, which have been mainly used in the prior art, received light through a backlight unit because it was difficult for LCDs to emit light on their own. The backlight unit is a device that uniformly supplies a light source and light supplied from the light source to a liquid crystal positioned on the front side. As the backlight unit became thinner, it was possible to implement a thin LCD, but it is difficult to implement the backlight unit with a bendable material, and when the backlight unit is bent, it is difficult to uniformly supply light to the liquid crystal, resulting in a problem in that the brightness of the screen changes.

On the other hand, in the case of LED or OLED, since each element constituting the pixel emits light on its own, it can be implemented curved without using a backlight unit. In addition, since each element emits light itself, even if a positional relationship with neighboring elements is changed, its own brightness is not affected. Therefore, it is possible to implement a bendable display 180 using LED or OLED.

OLED (Organic Light Emitting Diodes, Organic Light Emitting Diodes) displays 180 appeared in earnest in the middle of 2010, and are rapidly replacing LCDs in the small and medium display market. OLED is a display made using a self-luminous phenomenon that emits light when current flows through fluorescent organic compounds.

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

An LED (Light Emitting Diode, Light Emitting Diode) display 180 is a technology that uses one LED element as one pixel, and can implement a bendable display 180 by reducing the size of the LED element compared to the prior art. Conventionally, a device called an LED TV uses LED as a light source for a backlight unit that supplies light to an LCD, but the LED itself did not constitute a screen.
