Liquid Crystal Displays (LCD). Liquid crystal displays, once limited to small devices such as calculators, are now displacing color CRT (cathode ray tube) displays in commercial quantities. The ability to fabricate these display devices at high quality and at low cost is partially due to the wider spread use of photopolymer-based materials. Photopolymer technology is being used for the alignment of liquid crystal (LC) elements (49), the orientation of ferroelectric materials (50), the synthesis of LC polymers (57) and the manufacture of color filters for liquid crystal display applications (52). 

In a liquid-crystal display (LCD) device, the two electrodes are parallel and separated by a thin layer of liquid crystal (see Figure 2.2). The liquid crystals in this layer naturally adopt a helical structure. 

Over the last 50 years, remarkable improvements in the performance of vapor-deposited OLEDs have been made. Operating voltages have been decreased from a few kilovolts to a few volts, at the same time efficiencies are now approaching 100 lm/W. These improvements in device performance have made commercial displays based on vapor-deposited OLEDs viable. This technology is now poised to compete with liquid crystal displays (LCDs) in an expanding flat panel display marketplace. 

G.3.3.3 Liquid Crystal Displays (LCDs). Liquid crystalline polymers, first intro-dnced in Section 1.3.6.3, are ntilized for a different type of computer and television display, the liquid crystal display (LCD). Most of today s laptop computers and handheld devices ntilize color flat panel displays where the light transmission from the... 

A PLZT reflective display is similar in appearance to the common liquid crystal display (LCD). The structure of the device is shown schematically in Fig. 8.16 a suitable PLZT composition is the slim-loop quadratic 9.5/65/35. 

Therefore, the wide variety of molecular properties provides unlimited possibilities of generating machines and devices, as illustrated in Fig. 44. Many of them [e.g., organic light emitting devices (OLEDs), liquid-crystal displays (LCDs)] are already available as commercial products. 

LCD is short for liquid crystal display. LCDs are devices that use liquid crystals to create images. Liquid crystal images are being used in watch faces, laptop computer screens, camcorder viewers, virtual reality helmet displays, and televisiou screens. 

Indium has a number of interesting properties. For example, it has a low melting point for metals, 313.9°F (156.6°G). When pure, it sticks very tighdy to itself or to other metals. This property makes it useful as a solder. Solder is a material used to join two metals to each other. Other uses of indium are in the manufacture of batteries, electronic devices, liquid crystal displays (LCD), and in research.
