摘要： A substantially U-shaped gas discharge lamp (1′), containing mercury for the gas discharge, is connected to a high-frequency driver circuit (6′). To ensure that the gas discharge lamp operates with minimum loss and maximum light yield, the respective output terminals (4′, 5′) of the high-frequency driver circuit are not electrically grounded and the central section (11′) of the gas discharge lamp is capacitively coupled to an electric ground. A substantial reduction of lamp current in the central section is ensured, thus lowering thermal production in the central section of the gas discharge lamp. Accordingly, the central section becomes the coldest place in the gas discharge chamber and the place where condensation of the mercury occurs. The mercury vapor pressure can thus be regulated and the light yield optimized.

摘要： A high-resolution field emission display that applies a field emission device (or a field emission array) being an electron source element to a flat panel display device. The field emission display includes an upper plate and a lower plate that face each other, wherein the lower plate and the upper plate are vacuum-packaged in parallel positions. A dot pixel of the lower plate includes a high-voltage amorphous silicon thin film transistor formed on the glass substrate of the lower plate, a diode type field emission film partially formed on the drain of the high-voltage amorphous silicon TFT, a passivation insulation layer formed on the high-voltage amorphous silicon TFT and the lateral side of the diode type field emission film, and an electron beam focusing electrode/light-shading film which vertically overlaps with the high-voltage amorphous silicon TFT on some parts of the passivation insulation layer and is formed on a lateral side of the diode type field emission film. A dot pixel of the upper plate includes a transparent electrode formed on the glass substrate of the upper plate, and a red, green or blue phosphor formed on some parts of the transparent electrode. Therefore, the high-resolution field emission display device can obtain an effect of focusing the electron beam trajectory and a light-shading effect for the TFT at the same time, and thus remarkably enhance the performance and the resolution of the field emission display.

摘要： A PDP apparatus in which degradation in image quality such as display missing points does not occur, even if the peak luminance is increased, has been disclosed. In the PDP apparatus, the display load ratio of each subfield is detected and a sustain pulse cycle is changed according to the display load ratio of each subfield. Moreover, an adaptive sustain pulse number change means is provided, which calculates the total amount of variations in time by summing the variations in time in a display field caused by the changes in the sustain pulse cycles and increases/decreases the number of sustain pulses of each subfield according to the total amount of variations in time.
