Sputtering of the cathodes of a cold cathode fluorescent lamp is reduced or eliminated by removing electrodes altogether from the sealed envelope containing the gaseous medium. Electric field is then applied by means of electrically conductive members outside the tube. Alternatively, the current passing between electrodes can be spread over multiple sub-electrodes so that the current flow and sputtering experienced by each individual sub-electrode will be reduced. Different designs are employed to facilitate heat dissipation for high power and high intensity cold cathode fluorescent lamp applications. Thus, a container for the fluorescent lamp tube may be omitted altogether and adjacent rounds of a spiral-shaped lamp may be attached together by an adhesive material. Alternatively, the container may be open at one end to facilitate heat dissipation. Or the container for the lamp and the housing from the driver may each contain a hole to allow air circulation to carry away heat.

Strips of field emitters arranged in rows overlap grid electrodes when viewed in the viewing direction to define pixel dots. Scanning electrical voltages are applied to the rows of field emitters to perform scanning and data potentials are applied to the grid electrodes to control the brightness of the display. Potentials applied to the grid electrodes also focus the electrons from the field emitters. A metal mesh with grid electrodes fabricated thereon to form an integrated structure greatly simplifies the manufacture of the display.

Cold cathode field emitter flat screen display

An improved cathodoluminescent device with a one piece spacer structure which is rigidly connected to two sets of grid electrodes. The spacer structure defines holes therein that spatially match pixel dots on an anode on a face plate. One set of grid electrodes comprises layers of electrically conductive material on surfaces within at least some of the holes of the spacer structure. The two sets of grid electrodes and different spacer layers may be attached together to form a one piece spacer structure integral with the two sets of grid electrodes. The display device is then simply assembled by matching each of the holes of the spacer structure with a pixel dot on the face plate, and attaching the structure to the face plate and a back plate.

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.
