Splicing unit thin, lightweight Character LCD Modules liquid crystal mosaic

LCD full name in English LiquidCrystalDisplay, TFT Display Module is the structure of two parallel glass in which the liquid crystal placed, the middle two pieces of glass with many tiny vertical and horizontal wires, or to control rod through the energized crystal molecules change direction, reflecting the light generated screen.
LCD consists of two glass composition, thickness of 1mm, during which the liquid crystal material contains 5 m evenly spaced intervals. Because the liquid crystal material itself is not light, so both sides of the screen with the lamp as a light source, and in the back there is a backlit LCD display panel (or even light panels) and reflective film, backlit panels are composed of a fluorescent substance can emit light, its main function is to provide a uniform background light.
Light emitted by the backlight passing through the polarizing filter layer after the first layer containing the liquid crystal droplets thousands crystal layer.
The droplets of the liquid crystal layer are included in the small cell structure, one or more cells constitute one pixel on the screen. Between the glass and the liquid crystal material is a transparent electrode, the electrode is divided into rows and columns, the intersection of row and column, the voltage is changed by changing the optical state of the liquid crystal, the liquid crystal material acts like a small light valve .
The liquid crystal material is the control circuit portion and a peripheral driving circuit portion. When the Low Temperature Display of the electrode generating an electric field, the liquid crystal molecules will be distorted, and thus will pass through one of the refraction of light in a regular, and then through the second layer of the filter layer filtering is displayed on the screen.
The LCD is only in recent years developed a splicing technology, its greatest advantage is its low power consumption, light weight, long life, no radiation, screen brightness uniformity, etc., but the biggest drawback is that LCD larger patchwork . Only a fraction of a millimeter and DLP patchwork is unable to compete. The display requires very sophisticated users, a little bit of regret, which is currently only occupy LCD splicing key factor in low-end market.
To reduce patchwork, patchwork gives users reduce the interval sense, LCD manufacturers have been stitching also constantly work with. Among the many manufacturers, Samsung is undoubtedly the most praiseworthy. In recent years, Samsung has introduced a more narrow patchwork LCD splicing unit, from the initial 7.3mm, to 6.7mm, and then in 2011 launched a new 5.5 mm LCD splicing unit, Samsung lead the way, and continue to regard the patchwork breakthrough, setting off a wave of LCD splicing again and again.
