    • In a so-called multiline driving system, (1) a selected period is divided into a plurality of subselected periods (t11, t21, t31 and t41) and the subselected periods are dispersed in one-frame period, and (2) each subselected period is further divided into a plurality of divided subselected periods ((s1, s2), (s3, s4), (s5, s6), (s7, s8)). The potentials of selected signals are interchanged in the divided subselected periods in one frame so as to offset the influence of a spike-like voltage from the scanning signal impressed upon adjacent scanning electrodes. By this invention, (1) uneven display in the direction of signal electrodes (generally, in the longitudinal direction) can be suppressed, (2) uneven display in the direction of signals electrodes does not become more marked and no flickering occurs even when displayed contents momently change, and (3) no uneven display occurs in the direction of the scanning electrodes (generally, in the lateral direction).

    • A display device employing a multi-line driving method, which improves display quality by applying contrivances to the construction of a data line driving circuit and a scanning line driving circuit. Frame memories (252) are prepared for two frames, for example, and they are alternately switched between input and output for each frame. When the memory of only one frame is used, the data corresponding to the number of scanning lines driven simultaneously are gathered together and simultaneously written. In this way, the deterioration of display quality can be prevented. A decoder in a data line driving circuit is formed into a ROM (262). Accordingly, the construction of the data line driving circuit can be simplified. The voltage applied to each data line is fixed during the period in which it does not contribute to image display. In this way, cross-talk can be prevented. Data necessary for selecting a scanning line and data necessary for determining a voltage to be applied to the scanning line are separately processed in a scanning line driving circuit (2200). In this way, the construction of the scanning line driving circuit can be simplified. When a scanning voltage pattern is periodically changed, the scanning line driving circuit and the data line driving circuit exchange information on the scanning voltage pattern with each other.
    • 一种采用多线驱动方法的显示装置,其通过对数据线驱动电路和扫描线驱动电路的构造施加设计来提高显示质量。 例如,帧存储器(252)准备用于两个帧,并且它们在每帧的输入和输出之间交替地切换。 当仅使用一帧的存储器时,与同时驱动的扫描线数相对应的数据被聚集并同时写入。 以这种方式,可以防止显示质量的恶化。 数据线驱动电路中的解码器形成为ROM(262)。 因此,能够简化数据线驱动电路的结构。 施加到每个数据线的电压在其对图像显示没有贡献的时段期间是固定的。 以这种方式,可以防止串扰。 在扫描线驱动电路(2200)中分别处理选择扫描线所需的数据和确定施加到扫描线的电压所需的数据。 以这种方式,可以简化扫描线驱动电路的结构。 当扫描电压图案周期性地改变时,扫描线驱动电路和数据线驱动电路将关于扫描电压图案的信息彼此交换。

    • A carrier used for an IC handler for conveying devices to be tested. Even when devices have narrow lead pitches, this carrier can easily and stably carry and position them. Two contact holes having an elongated shape and substantially parallel to each other are formed in the bottom of a box-shaped body whose upper surface is open, in a gap corresponding to the gap of lead pin arrangements of two lines of lead pins of the devices to be accommodated therein. Each contact hole has a length corresponding to the length of each lead pin arrangement and has a width capable of accommodating each lead pin arrangement. Carrier guides are formed in the proximity of both ends of each contact hole in the longitudinal direction in such a manner as to protrude upward by a predetermined height from the bottom of the box-shaped body. The length between the side surfaces of these carrier guides is selected so that the devices can be accommodated between their opposed side surfaces in a direction transversely crossing the contact holes. On the other hand, a socket for applying electrical signals to the device has two rows of socket terminals in the same number and with the same pitch as those of each lead pin arrangement of the device, with substantially the same gap as the gap between the contact holes, and a thin sheet-like insulating member is interposed between adjacent socket terminals of each socket terminal arrangement. The socket terminal is fitted into the contact hole during the test and is electrically connected to the lead pins of the device.

    • A display driving method, wherein only one voltage of an unselected scanning line is used, and when the displaying of an image by display elements is not carried out, the voltage level of data lines corresponding to the display elements is the voltage level of the unselected scanning line. The power consumption of the display can be reduced. The smallest possible area out of the whole screen is used for the displaying of an image, and the other area is put in a display-off state (display-off mode) by using this driving method. For example, the reduction of the consumption of the display in a standby mode is effected. The image display area and the area in a display-off state can be set freely, respectively. When the multiline driving method and the above-described driving method are combined, the power consumption can further be reduced.
