摘要:
A three-electrode surface-discharge alternating-current plasma display panel (AC PDP) has maintenance discharge electrodes that are in parallel with one another and addressing electrodes that are orthogonal to the maintenance discharge electrodes. The maintenance discharge electrodes are connected to one another, and the maintenance discharge electrodes are independent of one another and correspond to display lines that form a screen of the PDP. Wall charges are accumulated to serve as memory media. Display data are written to the screen in separate two periods, i.e., an addressing period in which wall charges are accumulated according to the display data, to prepare for maintenance discharge (sustain discharge) and a maintenance discharge period in which the maintenance discharge is repeated to emit light. The maintenance discharge in the maintenance discharge period is carried out on every other display line and the accumulation of wall charges in the addressing period is carried out on every display line. This arrangement scans every other display line on the screen according to interlaced display signals (video signals) without producing new display data by line interpolation, thereby shortening an addressing time.

A method of controlling the gray scale of a plasma display device has a forming step of forming a frame for an image by a plurality of subframes each having a different brightness, a setting step of setting the number of sustain emissions of each subframe in an anti-geometrical progression corresponding to the brightness of each subframe, and a displaying step of displaying the image on the plasma display device by a gray scale display having a specific brightness. The number of sustain emissions in each subframe is set individually by the each subframe, and this establishes a linear relation between the gray level and the corresponding brightness Therefore, an enhancement of display quality of the plasma display device can be realized.

摘要:
A display apparatus, that can prevent thermal destruction and burning with a simple structure, has been disclosed. In the apparatus it is judged that there is possibility of a pattern, whose area with high brightness is small, being displayed frequently, when a state in which the total light emission pulse number remains large occurs with high frequency, and if such a state is detected, the total light emission pulse number (sustain frequency) is reduced to prevent the thermal destruction and burning.
摘要:
A technique which relates to discharge in sustain operation of a PDP device and a driving waveform thereof, and which can improve luminous efficiency to achieve stability while reducing a possibility of failure of discharge is provided. In a generating operation of a sustain pulse in a sustain pulse generating circuit, after LU-ON (t1 to t2), a voltage applied on electrodes is raised up to a sufficiently-high voltage, namely, a sustain voltage according to an ON state of a CU circuit (t2 to t3), and discharge is started, CU is once turned OFF (t3), then a first discharge peak is formed (t11). Thereafter, CU is turned ON again before discharge is converged (t12) to raise a voltage value and form a second discharge peak (t14). Since a voltage Vi to start discharge is sufficiently high, a possibility of discharge failure is suppressed, and an effect of improvement in luminous efficiency is not ruined.
