The present invention relates to an LCD module used as a computer monitor or a display such as a television, a mobile phone, navigation, PMP, PDF, PSP, etc. More specifically, to form a light emitting frame having a variety of shapes and colors on the edge of the LCD module By using the frame's original color printing unit, it is possible to selectively use a display having a preferred border color according to the user's preference, but when the frame is emitted, the entire outside of the LCD panel is brightened. The improvement is, of course, mixed with the color provided from the light emitting means to express a new color, and the LCD module having a direct-view color light emitting frame that can be utilized as a mood mood light at night.

In recent years, various display apparatuses are being manufactured to have a thinner thickness using LCDs, and display apparatuses using such LCDs are used as liquid crystals of televisions or mobile phones as well as computer monitors.

Unlike CRT, which has been used in the related art, the LCD is an electric device that transmits various electrical information generated by various devices to visual information by using a change in transmittance of the liquid crystal according to an applied voltage. Backlight is required, but it is a kind of flat panel display that is widely used because it consumes less power and is convenient to carry.

Such LCDs are generally STN-LCD (advanced liquid crystal display), TFT-LCD (thin film transistor liquid crystal display), UFB-LCD (Ultra Fine & Brightness-LCD), TFD-LCD (thin film diode liquid crystal display), It is classified as organic EL and the most widely used among them can be defined as TFT-LCD.

In particular, the thin film transistor liquid crystal display widely used in recent years is composed of a thin film transistor and a lower plate on which pixel electrodes are arranged, an upper plate composed of a color filter and a common electrode for displaying colors, and a liquid crystal filled between the two glass substrates. On both sides of the two glass substrates, polarizing plates for linearly polarizing visible light (natural light) are attached to each other. This type of liquid crystal display is called TFT-LCD.

TFT-LCD consists of a switching element TFT, a capacitor formed by the liquid crystal between the upper and lower electrodes, an auxiliary charger, a gate electrode that controls the on / off of the TFT, and an image signal electrode. Stored in the two chargers described.

In addition, by applying a voltage to the gate of the TFT forming the pixel by an external peripheral circuit, the transistor is turned on so that the image voltage can be input to the liquid crystal, and then the image voltage is applied to the liquid crystal. After storing the information, the transistor is turned off so that the charge stored in the liquid crystal charger and the auxiliary charger is preserved so that the image is displayed for a certain time. When voltage is applied to the liquid crystal, the arrangement of the liquid crystal changes. When the light is transmitted, diffraction occurs and the light is transmitted through the polarizing plate to obtain a desired image. Since the 1990s, the liquid crystal display has been put into practical use, and the market scale is rapidly expanding, and is widely used in various fields throughout the industry.
