Crystal Display Devices

A recent publication describes a pragmatic approach for developing a thermosetting anisotropic conductive adhesive film to electrically connect a flexible circuit to ITO terminal pads [121], The basic components are a solid high molecular weight bisphenol-A diglycidyl ether, a liquid bisphenol-F diglycidyl ether, a phenoxy resin M = Tg = 94°C), (2,3-epoxypropyl) 

A process for chip-on-glass bonding of bumped integrated circuits to ITO conductors has been developed by using a two-part isotropic epoxy adhesive loaded with silver flakes [122]. The first observation is that the volume resistivity and contact resistance depend on the type of flakes and the percentage by weight of particles dispersed in the adhesive composition. According to the kind of flakes, the volume resistivity of adhesives loaded with 75-80 wt% silver varies 

Currently, the limit of the connection pitch of anisotropic adhesives is held to about 100 xm to circumvent possible shorting between neighbouring conductors. An ideal process would be to avoid the use of a conductive adhesive by performing a direct metal-to-electrode contact between the conductive tracks of the flexible circuit and the electrodes of both the electronic driver and the display panel.

Worked Example 10.1 shows how to calculate the Frank-Oseen free energy and use it to predict the response of a liquid crystal to a magnetic or electric field. Such calculations are used to design practical liquid-crystal display devices. They also can be used to determine the values of the elastic constants.

Polymer Network Stabilized Liquid Crystal Displays. The alignment of liquid crystals plays an important role in the operation of a display. The alignment is conventionally induced by the display cell surfaces, but by distributing the surface of a polymer network through out the bulk of the liquid crystal, new properties are possible, and the performance of conventional devices can be improved. This short section will mention some of the conventional liquid crystal display devices modified by these polymer networks. 

Polyimides have been widely used in the advanced microelectronics industry such as passivation or stress-relief layers for high-density electronic packaging, interlayer dielectric layers for wafer-level semiconductor fabrication, or alignment layers for liquid crystals in advanced liquid crystal display devices (LCDs) owing to their outstanding thermal, mechanical and good insulation properties with low dielectric constant, good adhesion to common substrates and superior chemical...

In general, a color liquid crystal display device consists of a color filter and an electrode substrate which face each other (49). A spacer is provided in the gap between the layers to keep a ceU gap between the color filter and the electrode substrate constant and uniform. As the spacer, pearls with a fixed particle diameter are dispersed.
