    • Control side equipment and at least one equipment under control are commonly interconnected via a data line and a strobe line. The equipment under control is provided with means for retaining the logic of a strobe pulse when it is received from a strobe line. When the control side equipment has set data on the data line and provided the strobe pulse on the strobe line, the logic hold means of the equipment under control holds the logic of the strobe pulse and the data set on the data line is fetched therefrom into the equipment. Thereafter, the logic hold is released to thereby inform the control side equipment that the equipment under control is ready for receiving the next data. The control side equipment monitors the strobe line and, upon detection of the information, sets new data on the data line and sends out a strobe pulse. Thereafter, similar operations are carried out, by which data are sequentially transferred from the control side equipment to the equipment under control. In the case of transferring data from the equipment under control to the control side equipment, when the control side equipment sends out a strobe pulse representing that it is ready for receiving data, the logic hold means of the equipment under control holds the logic of the strobe pulse, data is set on the data line and then the logic hold is released, by which the control side equipment is informed that the data to be transferred has been set. Upon detection of releasing of the logic hold by monitoring the strobe line, the control side equipment fetches the data from the data line and when it has become ready for receiving the next data, it sends out a strobe pulse again, thus, fetching data one after another.

    • A method and a system for driving an electro-luminescence display panel of a matrix type has a compensation pulse applied to all the cells prior to or in the front of a pedestal pulse on every frame cycle. The level of the compensation pulse is higher than the pedestal pulse but low enough not to light the cells by itself. The duration of the compensation pulse is long enough to saturate charge polarization in the EL material of the cell, as a dielectric, at the applied voltage. Therefore, brightness of the lighted cell is kept constant regardless of the number of lighted cells on the same data electrode. Each of two power-receiving terminals of push-pull scan drivers is connected to a pulse generator respectively. One of the two power-receiving terminals may be floated from the pulse generator while data pulse is applied to the data electrodes. This configuration prevents damage of the CMOS drivers by latch-up caused therein, as well as reducing power consumption produced by charging current of the data pulses into non-lighted cells.
    • 用于驱动矩阵型电致发光显示面板的方法和系统具有对每个帧周期的基准脉冲之前或之前的所有单元施加的补偿脉冲。 补偿脉冲的电平高于基座脉冲,但足够低,不能自己点亮单元。 在施加的电压下,补偿脉冲的持续时间足够长以使电池的EL材料中的电荷极化作为电介质饱和。 因此,与同一数据电极上的点亮单元数量无关地,点亮单元的亮度保持恒定。 推挽扫描驱动器的两个受电端子中的每一个分别连接到脉冲发生器。 两个电力接收终端中的一个可以从脉冲发生器浮起,而数据脉冲被施加到数据电极。 这种配置防止CMOS驱动器由于其中引起的闩锁而损坏,以及减少由数据脉冲的充电电流产生的功率消耗到非点亮的单元。
