    • There is provided a device for driving a light-emitting display panel in which output limiter element is added to a DC-DC converter which associates a boosting operation. In the drive device, even though a forward voltage of a monitor element increases to operate the limiter element, predetermined display quality can be assured without considerably disrupting a color balance. On a display panel, a display region in which display pixels of R, G, and B are arranged and an arrangement region for monitor elements which monitor forward voltages of R, G, and B are formed. Output voltages obtained by the respective DC-DC converters are controlled based on the forward voltages obtained by the monitor elements. An output limiter is constituted by zener diodes to prevent converter output values from being excessive by increases in forward voltages from the monitor elements due to aging. Limiter values obtained by the zener diodes are set at different levels.
    • 提供了一种用于驱动发光显示面板的装置,其中将输出限制器元件添加到将升压操作相关联的DC-DC转换器。 在驱动装置中,即使监视器元件的正向电压增加以操作限制器元件,可以确保预定的显示质量,而不会显着地中断色彩平衡。 在显示面板上,形成有布置有R,G,B的显示像素的显示区域,并形成监视R,G,B的正向电压的监视元件的配置区域。 基于由监视器元件获得的正向电压来控制由各个DC-DC转换器获得的输出电压。 输出限幅器由齐纳二极管构成,以防止转换器输出值由于老化引起来自监视器元件的正向电压的增加而过度。 由齐纳二极管获得的限幅值设定在不同的水平。
