摘要： A display panel 1, in which light-emitting elements E11 to EMN are connected in a matrix state to the respective intersecting positions of a plurality of signal lines A1 to AM and a plurality of scan lines K1 to KN, is used. A scan line Kn is set to a scan selection potential (ground potential), and a pulse voltage from a pulse power supply 4 is applied to the other scan lines. When switches Sa1 to SaM as data selection means in a data driver 2 are placed in a state shown in a drawing, respective currents are applied to light-emitting elements to be emitted in a forward direction as rush currents through the parasitic capacitances of light-emitting elements in a non-scan state when the pulse voltage rises.

摘要： Treating light emitting elements 2 in all the display pixels in a light emitting display panel as objects, a maximum value of the forward voltages is drawn by a multi-input comparator 3a and a peak hold circuit 3b. Based on the maximum value of the forward voltages, a voltage boost circuit 6 switching operates a power FET to supply a boosted output by this operation to a constant current circuit 1 as the operational voltage VH. In the case where the maximum value of the forward voltages increases due to trouble or the like and based on this increment the operational voltage VH excessively increases, the operation of the voltage boost circuit 6 is stopped by a control output from an analog comparator 7a which functions as a voltage limiter.

摘要： One frame (period) is divided into a plurality of sub-frames including a lighting period and a non-lighting period for a pixel, and gradation control is carried out by selecting the above-mentioned sub-frames and by summing the lighting periods of the pixel within one frame period. In addition, proportions of the above-mentioned lighting period and the non-lighting period for every sub-frame are changed so as to perform selection operation of a gamma value of a gradation characteristic. A sum of the lighting periods within one frame period of the pixel at the time of setting the maximum gradation by way of the above-mentioned gradation control is set to be the same at the time of selecting any gamma value selected by the above-mentioned gamma value selection operation. Thus, it is possible to control luminosity changes generated when switching gamma values of gradation characteristics, especially at the time of the maximum gradation, and reduce degrees of a user's sense of incongruity.

摘要： A light-emitting device (10) includes a first light-emitting region (100) and a second light-emitting region (200). The first light-emitting region (100) emits a light ray having a first color by making a first light-emitting layer group including at least two or more kinds of light-emitting layers emit light. In addition, the second light-emitting region (200) emits alight ray having the first color (for example, daylight color, natural white color, white color, warm white color, or incandescent color) by making a second light-emitting layer group including at least two or more kinds of light-emitting layers emit light. In addition, at least one kind of light-emitting layer included in the second light-emitting layer group emits a light ray having a different spectrum peak from all of the light-emitting layers included in the first light-emitting layer group. Therefore, the color-rendering properties of light emitted from the light-emitting device (10) are improved.

摘要： A clock signal in synchronization with a data writing signal, every scanning line, which is supplied from a light-emitting control circuit 4 to a scanning driver 6, is supplied to an oscillator 12 which generates a reference switching signal, according to a PWM method, in a DC-DC converter 8. Thereby, the timing at data writing every scanning line is in synchronization with the phase of a ripple component superimposed on a driving voltage Va from the DC-DC converter 8. Accordingly, a problem that there is caused a state in which light-emitting intensity is different every scanning line can be solved because the same voltage Vgs between a gate and a source is supplied every scanning line to a light-emitting driving transistor Tr2 at any time even if the ripple component by switching of the DC-DC converter is superimposed on the driving voltage Va. Thereby, a problem that the display quality of images is remarkably reduced can be prevented in a light-emitting driving operation of a display panel, wherein the operation has a configuration in which an organic EL element with a light-emitting intensity characteristic of a current dependence type, for example, is used as a pixel.

摘要： Power saving is more realized when a partial display is executed in active matrix type EL display elements. When the partial display is executed, a scan driver 2 repeatedly scans all the scan lines as executed ordinarily. In contrast, when a scan shifts from a display region to a non-display region, black display data is captured by a shift resister 1a in a data driver 1 for one horizontal period and latched by a latch circuit 1b. Then, while the non-display region is being scanned, the drive of the data driver 1 is stopped. Accordingly, in the scan of the non-display region, a non-display state is achieved by the black display data latched by the latch circuit 1b. Low power consumption can be realized because the drive of the data driver 1 operating at a high speed is stopped while the non-display region is being scanned.
摘要翻译：当在有源矩阵型EL显示元件中执行部分显示时，能够实现省电。当执行部分显示时，扫描驱动器2通常重复扫描所有扫描线。相反，当扫描从显示区域移动到非显示区域时，黑色显示数据由数据驱动器1中的移位寄存器1a捕获一个水平周期并由锁存电路1b锁存。然后，在扫描非显示区域的同时，停止数据驱动器1的驱动。因此，在非显示区域的扫描中，通过由锁存电路1b锁存的黑色显示数据来实现非显示状态。由于在扫描非显示区域的同时停止高速运转的数据驱动器1的驱动，所以能够实现低功耗。
