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.

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.

The present invention relates to a flat parallel light source using the principle of the mirror reflection and diffuse reflection, which comprises a light source, a diffuse reflective chamber with high reflectance walls, a light coupler, a small hole array at the top surface of said diffuse reflective chamber, a mirror reflective cone array on the small hole array, and a convex lens array on said cone array. The light generated by the light pass through the light coupler into the diffuse reflective chamber, and then pass through the small hole array, mirror reflective cone array, and lens array to form parallel light. The flat parallel light source can generate a high intensity parallel light with excellent parallelism or a given scattering angle parallel light. It can be used for backlighting for all kinds of LCDs, and other equipment where parallel light is needed. It can also be used in LCDs to increase the brightness of the display image and reduce power consumption.

A new kind of Active-Matrix LCD, called Out-Active-Matrix LCD ('OAM-LCD'), is formed by depositing the active-matrix on the outside surface of the LCD substrate. Each active component is connected with a related dot electrode of the LCD cell through thin conductive lead, which is hidden in the substrate. This OAM-LCD not only makes the large screen LCD feasible, but also is easy to manufacture. The OAM-LCD can use transmission LC or scattering LC. This new OAM-LCD can be used for making large screen hang-on-wall TV, and super large screen mosaic video display both indoor and outdoor applications. OAM-LCD's features include high brightness, high efficiency, good color quality, long lifetime, low cost and high contrast, especially under high ambient illumination, such as trader direct sunlight.
