Backlight Module, the light source of TFT-LCD, is constructed by optical films, light guide plate, LED light bar, back-cover and plastic case. Because the liquid crystal molecule only function as the penetration level that doesn't illuminate spontaneously, it is necessary to add a backlight module. Without a backlight source, the liquid crystal display module would only present a pitch-black screen, and no matter how the internal liquid crystal molecules rotate, nothing would be visible from the outside. Backlight sources can be classified into two types according to their light emission:. A backlight module is a core component of an LCD, providing stable, high-brightness light for clear image display. It's the system that turns invisible light into the vivid images you see. As an LCD display manufacturer, CNK Electronics Co.

An electro–optic modulator (EOM) is an optical device in which a signal-controlled element exhibiting an electro–optic effect is used to modulate a beam of light. The modulation may be imposed on the phase, frequency, amplitude, or polarization of the beam. Modulation bandwidths extending into the gigahertz range are possible with the use of laser-controlled modulators. The electro–opti. Phase modulationPhase modulation (PM) is a modulation pattern that encodes information as variations in the instantaneous phase of a. A phase modulating EOM can also be used as an amplitude modulator by using a. This alternative technique is often used in where the requirements of phase stabi. Depending on the type and orientation of the nonlinear crystal, and on the direction of the applied electric field, the phase delay can depend on the polarization direction.
