A light transmitting container is used to house a cold cathode fluorescent lamp (CCFL) to reduce heat loss and to increase the luminous efficiency of the lamp. An electrical connector configuration is connected to an electrode of the lamp and adapted to be electrically and mechanically connected to a conventional electrical socket. A driver circuit in the container converts 50 or 60 Hz power to the high frequency power suitable for operating the CCFL. At least one of the electrodes of the CCFL is outside of the container to facilitate heat dissipation. A two-dimensional array of CCFLs may be held by a module housing to form a display for displaying still or moving images and characters. The above-described CCFL configurations may also be used for displaying traffic information. A monochromic, multi-color and full-color cold cathode fluorescent display (CFD), comprises: some shaped white or multi-color or red, green, blue three primary color CCFLs, reflector, base plate, temperature control means, luminance and contrast enhancement face plate, shades and its driving electronics. CFD is a large screen display device which has high luminance, high efficiency, long lifetime, high contrast and excellent color. CFD can be used for applications both of outdoor and indoor even at direct sunlight, to display character, graphic and video image.

Cold cathode fluorescent lamp and display

A light transmitting container is used to house a cold cathode fluorescent lamp (CCFL) to reduce heat loss and to increase the luminous efficiency of the lamp. An electrical connector configuration is connected to an electrode of the lamp and adapted to be electrically and mechanically connected to a conventional electrical socket. A driver circuit in the container converts 50 or 60 Hz power to the high frequency power suitable for operating the CCFL. At least one of the electrodes of the CCFL is outside of the container to facilitate heat dissipation. A CCFL having an elongated tube portion and enlarged portions for housing larger electrodes is proposed to enhance the longevity and brightness of the CCFL. Larger electrodes are used to generate more electrons in the CCFL, thereby generating more light. Larger electrodes also reduces the temperature of the tube material of the CCFL to enhance the lifetime of the device.

An active matrix LCD employs a two-terminal or three-terminal switch structure employing an electrically conductive wire. The wire has an insulating layer thereon forming a wire structure. The wire structure is placed in a groove in a transparent substrate and an electrode layer is deposited on the insulating layer at spaced intervals to form an array of diodes connected in parallel. By applying a suitable voltage to the wire, all of the diodes in parallel are turned on to charge the electrodes to desired electrical potentials on one side of the liquid crystal material. An array of electrodes matching the position of the diodes on the other side of the liquid crystal material are charged to the desired potentials in order to control the color and brightness of the display by controlling the light transmittance of the liquid crystal cells between the two sets of electrodes. In another embodiment, a three-terminal switch device is used instead, where the switch includes an insulating layer on a conductive wire and a semiconductor layer on top of the insulating layer. A conductive layer is then formed on top of the semiconductor layer to provide a source and a drain electrode with the wire acting as the gate of an array of transistors. When the common gate of the transistors is at On potential, the drain electrodes may be charged to the desired potentials in order to control the color and brightness of the display.
