LCD Back Light Photo Electric Sign ※ Features and Strengths 1. Provides bright and clear image to an electric sign, compared with other products through an application of back light, a core part of LCD technology. 2. Can be utilized as greatly clear and high quality photo panel with 5 million pixels during the day time and as a photo electric sign at night.

Description 1. The built-in back light in this medium is one of the core technologies for TFT-LCD. Because LCD is non-luminous itself, it is a unit to arrange light evenly to the information display. LCD consists of CCFL, a light guide plate and various thin Related technology patent No and No

Description 2. Our photo electric sign of LCD back light uses the high quality photo panel and special film with more than 5 mega pixels in order to realize prime photo image. Our product can be used as a high quality and highly clear photo panel during the day time, and can be used as a photo electric sign which maximizes the effect of the back light unit at night. Through electricity charge and supply as well as high capacity lithium battery inside the medium, our product is perfectly equipped with the condition as a PR system beyond time and space limit. This medium was developed in May, 2003, and is the product launched for the first time for various PR purposes. Our product provides an image different from existing products or new image, compared with the electric sign inserted with existing fluorescent light. We confidently present our product as an optimum for various PR activities.

Specification Dimension: 70 x 50 (Size is adjustable) LCD Back Light Unit Toshiba - Harrison (CCFL) Light Source Toray – Saehan Special Photo Film Sanyo High Capacity Lithium Battery and Charging Device 12V, 3A or Higher. 110/220 Adaptor

Technological Feature 1 Our product is brighter and clearer than other products, because it applies a back light, which is the core part of LCD, and utilizes our own patented LCD pattern. Because fluorescent light becomes brighter as it becomes smaller, 2.0mm of it is used, and so about 50% has been brighter than before. General fluorescent light is 40W, but our product uses 4.5W 4EA, and thus uses about 18W. Accordingly, power consumption is reduced at least by half. The life span of the fluorescent light used in our product is 40,000 hours, which is 8 fold longer than general one with 5,000 hours of life. In this regards, our product has a great merit in terms of durability.

Technological Feature 2 Special photo film, rather than general photo film, is used for the screen of an electric sign, and for this reason, clearness to the extent to express high quality digital screen with 5 mega pixels is provided. We think excellent PR will be made utilizing this film.

Technological Feature 3 Our product is used for multipurpose. With innovative development of PCB inverter, general DC adaptor can be used. Also, lithium battery and storage battery can be used for 6 hours. In view of all this, during various PRs period, our product can be used without separate power supply. In the case of lithium battery, which is mainly used for potable equipment consuming great electricity such as note book, we understand that lithium battery has not been used in the product of photo electric sign yet. Considering this, our product will be of great help to various events or PR activities.
