摘要： In the upper half and a lower half of a display area, scanning is implemented such that the directions of scan selection operations are different from each other. The upper half of the panel is scanned from the upper end to the center of the screen, and at the same time the lower half of the panel is scanned from the lower end to the center of the screen. Control is performed such that the difference between the start time of the scan selection operation of the upper half of display area and the start time of the scan selection operation of the lower half of the display area is scanning time of at least one or more scan lines. The configuration avoids a problem that a bright line is generated momentarily on the boundary line of the upper half and the lower half of the panel can be avoided.

摘要： There is provided a drive device for a light-emitting display panel which can reduce shadowing caused by an ON rate of light-emitting elements and a condition of dimmer setting to a level at which a problem is not posed. An analog video signal is supplied to a drive control circuit and an A/D converting circuit, and the analog video signal is converted into image data corresponding to each pixel in the A/D converting circuit. The image data is written in an image memory. The image data is read from the image memory every scanning operation, and the drive control circuit acquires a rate (ON rate of light-emitting elements in each scanning operation) of EL elements to be controlled to emit light. ON-drive data is read from a look-up table on the basis of the ON rate of the dimmer setting data. On the basis of the ON drive data, a drive current of a light-emitting element to be turned on is determined. Depending on ON-drive data corresponding to the ON rate and the dimmer setting, a light-emitting luminance of the light-emitting element is corrected, so that shadowing can be effectively suppressed from occurring.

摘要： In an upper half and a lower half of a display area, scanning is implemented such that the directions of scan selection operations are different from each other. That is, the upper half of the panel is scanned from the upper end to the center of the screen, and at the same time the lower half of the panel is scanned from the lower end to the center of the screen. Control is performed such that the difference between the start time of the scan selection operation of the upper half of display area and the start time of the scan selection operation of the lower half of display area is scanning time of at least one or more scan lines. By adopting such a scanning conformation, adjacent scan lines in the upper half and lower half of the display area are not simultaneously brought to a scan selection state, and thus a problem that a bright line is generated momentarily on the boundary line of the upper half and the lower half of the panel can be avoided. Further, since the time gap of scan timings close to the boundary line of the upper half and the lower half of the panel can be decreased, a problem that a figure which is moved and displayed as being laid across the upper half and the lower half is brought to a unnatural display state can be resolved.

摘要翻译： 在显示区域的上半部和下半部，进行扫描，使得扫描选择操作的方向彼此不同。 也就是说，面板的上半部从屏幕的上端扫描到屏幕的中心，并且同时将面板的下半部分从屏幕的下端扫描到屏幕的中心。 执行控制，使得显示区域的上半部分的扫描选择操作的开始时间与显示区域的下半部分的扫描选择操作的开始时间之间的差是至少一个或多个扫描线的扫描时间 。 通过采用这样的扫描构型，显示区域的上半部和下半部分的相邻扫描线不会同时变为扫描选择状态，因此存在在上半部分的边界线上立即产生亮线的问题 并且可以避免面板的下半部分。 此外，由于可以减少靠近面板的上半部和下半部分的边界线的扫描定时的时间间隔，所以存在如下问题：移动并显示为横过上半部和下半部 被带到不自然的显示状态可以解决。

摘要： After a command signal corresponding to a gradation whose light emission is controlled is outputted from a controller IC 4, based on this, a combination of respectively different intensity conversion data are extracted from a linear data table 11 and a γ correction data table 12. The respective intensity conversion data are analog converted by a first DAC 13 and a second DAC 14, and these are converted into a voltage level of a mean value by resistors R1, R2 and an addition circuit 15. By this voltage level of the mean value, an absorption current in a current mirror circuit 16 is controlled, and as a result, a drive current accompanied by y correction for the light emitting elements can be obtained by the current mirror circuit 16. The first DAC 13 and the second DAC 14 handle relatively simple intensity conversion data obtained from the linear data table 11 and the γ correction data table 12 and analog convert such data. Therefore, a light emission control circuit accompanied by γ correction can be realized without enlarging the circuit scale.

摘要： Light-emitting elements disposed on a light-emitting display panel are driven by constant currents, and the forward direction voltages of the light-emitting elements are obtained by a sampling/holding circuit. Then, the voltage output from a drive voltage source composed of a DC-DC converter is controlled by the forward direction voltages obtained by the sampling/holding circuit. For example, in a case in which the light emission luminance of the light-emitting display panel is changed or in other case, a sampling and holding operation is executed by the sampling/holding circuit in response to a control signal from a sampling timing control circuit at intervals shorter than ordinary intervals. With this arrangement, when light emission luminance of a light-emitting display panel is changed, the gentle changing characteristics of the light emission luminance thereof can be improved.
