摘要： PROBLEM TO BE SOLVED: To provide a drive apparatus in which the lower power consumption and higher reliability are attained at the same time, by suppressing differences in wave shapes between pulse voltages, regardless of the differences among impedances which are parasitic on the path between a recovery capacitor connected to each terminal of the capacitive load and the capacitive load.
SOLUTION: Two pulse generation sections (1X and 1Y) alternately apply a pulse voltage to both ends of a capacitive load (Cp). Power recovery sections (2X and 2Y) alternately turn on and turn off recovery switch elements (Q3X, Q4X, Q3Y and Q4Y), in synchronization with the rising/falling of the pulse voltage. Recovery inductors (LX and LY) resonate with the capacitive load (Cp) in the rising/falling periods of the pulse voltage. With this resonance, power is exchanged efficiently between the recovery capacitors (CX and CY) and the capacitive load(Cp). Between two recovery capacitors (CX and CY), second terminals (J2X and J2Y) are connected by a conductor (3C) and are substantially always maintained at the same potential.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for inspecting a display panel such as EL. SOLUTION: A Vdd voltage is applied to the source terminal of a driving TFT 11a and a VS1 voltage is applied to the cathode terminal of an EL element 15. ON voltage applied to gate signal lines 17a and 17b makes TFTs 11b, 11c, and 11d turn on, and a source signal line 18 enters an open state. A current Iw does not flow and all the current flowing to the driving TFT 11a becomes a current Idd flowing to the EL element 15. Pixels displayed on the display panel, therefore, all illuminate. If there is a pixel which does not illuminate, breakage of a TFT or low capacity is estimated.

摘要： PROBLEM TO BE SOLVED: To exactly and speedily acquire the optimal solution of a parameter group corresponding to request performance by making discrete the space of a circuit parameter within a realizing block and calculating the parameter while utilizing a genetic algorithm. SOLUTION: The realizing block of (n) circuit parameter spaces is equally divided and made discrete into np and when np discrete values are prepared, the number of (n) parameter sets becomes (np+1)n. In order to provide the optimal solution from a lot of sets, one set of parameter is regarded as one gene and (m) genes are extracted at random and regarded as an individual group. Therefore, (m) calculated results can be provided corresponding to the individual group having (m) genes. These calculated results are collated with the evaluation function of the request performance so that the individual conversion correction of (m) genes can be performed. The result is utilized for the next calculation and similar processing is repeated. Therefore, the individual group is converged by repeating the exchange of several generations and finally, most of individuals are optimized to the request performance.

摘要： PROBLEM TO BE SOLVED: To improve the luminance by increasing the light emitting area during an interlace emitting. SOLUTION: Reduction in the luminance is prevented by enlarging the area of a light emitting portion in accordance with an interlace signal. Moreover, in order to prevent the occurrence of a maloperation, sustain electrodes are divided into two groups A and B and the phases are made different from that of scan electrodes. In odd fields, addresses are made valid only for odd scan electrodes and A.C. pulses are applied to only sustain electrodes A during a light emitting. In even fields, addresses are made valid only for even scan electrodes and pulse voltages are applied between even scan electrodes and the sustain electrode group B for light emission. In oder to prevent the occurrence of a wrong discharging, odd scan electrodes and the sustain electrode group A and even scan electodes are made into a same phase so that no voltage is applied. Thus, utilizing the selection for every interlace, the area of non-light emitting portion is made small.
