Abstract: A voltage ratio regulator circuit for a spacer electrode of a flat panel display screen. Within one implementation of a field emission display (FED) device, thin spacer walls are inserted between a high voltage (Vh) faceplate and a backplate to secure these structures as a vacuum is formed between. A phosphor layer on the faceplate receives electrons selectively emitted from discrete electron emitting areas along the backplate (cathode) thereby forming images on the faceplate. The faceplate warms relative to the backplate, as a result of energy released by the phosphor layer, thereby generating a temperature gradient along the spacer walls. The top portion of each spacer wall becomes more conductive with increased temperature and acts to attract electrons that are emitted toward the faceplate. To counter this attraction, a spacer electrode is placed along each spacer wall at a height, d, above the backplate and maintained at a voltage, Ve. Electrodes of all of the spacer walls are coupled together. The spacer electrode at Ve and the high voltage supply at Vh are both coupled to a voltage ratio regulator circuit which maintains the ratio (Ve/Vh) using voltage dividers, an operational amplifier and other circuitry. The voltage ratio regulator compensates for variations in voltage supply performance. The time constants of the voltage ratio regular circuit is tuned to be near or slightly faster than the time constant of the inherent resistance and capacitance of the spacer wall. The invention can also correct for other sources of the voltage error on the spacer walls. The invention improves the electron path accuracy for pixels located near spacer walls.

Abstract translation: 一种用于平板显示屏的间隔电极的电压比调节器电路。 在场致发射显示器（FED）器件的一个实施方案中，在高电压（Vh）面板和背板之间插入薄间隔壁，以在两者之间形成真空来固定这些结构。 面板上的磷光体层接收从背板（阴极）离散的电子发射区域选择性发射的电子，从而在面板上形成图像。 作为由荧光体层释放的能量的结果，面板相对于背板加热，从而沿着间隔壁产生温度梯度。 每个间隔壁的顶部在温度升高时变得更加导电，并且用于吸引向面板发射的电子。 为了抵抗这种吸引力，沿着每个间隔壁沿着背板上方的高度d放置间隔电极并保持在一个电压Ve。 所有间隔壁的电极连接在一起。 Ve处的间隔电极和Vh处的高电压源均耦合到使用分压器，运算放大器和其他电路保持比率（Ve / Vh）的电压比调节器电路。 电压比调节器补偿电压供应性能的变化。 电压比常规电路的时间常数调整为接近或略快于间隔壁的固有电阻和电容的时间常数。 本发明还可以校正间隔壁上的电压误差的其它来源。 本发明改善了靠近隔离墙的像素的电子路径精度。

Abstract: Methods for compensating for brightness variations in a field emission device. In one embodiment, a method and system are described for measuring the relative brightness of rows of a field emission display (FED) device, storing information representing the measured brightness into a correction table and using the correction table to provide uniform row brightness in the display by adjusting row voltages and/or row on-time periods. A special measurement process is described for providing accurate current measurements on the rows. This embodiment compensates for brightness variations of the rows, e.g., for rows near the spacer walls. In another embodiment, a periodic signal, e.g., a high frequency noise signal, is added to the row on-time pulse in order to camouflage brightness variations in the rows near the spacer walls. In another embodiment, the area under the row on-time pulse is adjusted to provide row-by-row brightness compensation based on correction values stored in a memory resident correction table. In another embodiment, the brightness of each row is measured and compiled into a data profile for the FED. The data profile is used to control cathode burn-in processes so that brightness variations are corrected by physically altering the characteristics of the emitters of the rows.
