摘要： A D/A conversion circuit which can perform D/A conversion at high speed and with high precision is disclosed. The D/A conversion circuit comprises an analog reference power supply, an output buffer, a multiplexer, a pre-buffer, and a current changeover switch. The pre-buffer operates with a power supply voltage different from that of the analog reference power supply, and outputs a voltage substantially equal to an output voltage of the analog reference power supply. For a predetermined period after logic of digital data changes, the output voltage of the pre-buffer is supplied to the output buffer, and an input parasitic capacitor of the output buffer is charged/discharged. After the predetermined period elapses, the output voltage of the analog reference power supply is supplied to the output buffer. Therefore, a charging/discharging current of the input parasitic capacitor does not flow through the analog reference power supply, and fluctuation of the output voltage of the analog reference power supply can be suppressed.
摘要翻译：公开了一种可以高速，高精度地执行D / A转换的D / A转换电路。 D / A转换电路包括模拟参考电源，输出缓冲器，多路复用器，预缓冲器和电流切换开关。预缓冲器以与模拟基准电源不同的电源电压工作，并输出基本上等于模拟基准电源的输出电压的电压。在数字数据的逻辑变化之后的预定时间内，预缓冲器的输出电压被提供给输出缓冲器，并且输出缓冲器的输入寄生电容器被充电/放电。经过预定时间后，模拟基准电源的输出电压被提供给输出缓冲器。因此，输入的寄生电容器的充电/放电电流不会流过模拟基准电源，并且可以抑制模拟基准电源的输出电压的波动。

摘要： A transparent electroluminescent display panel overlaps at least a part of a conventional instrument panel, and forms a combined display panel assembly. Overlapping front and back panel displays are selectively displayed. The front electroluminescent panel displays additional information such as navigation maps, and is turned off when such additional information is not required while the back panel is turned on. The present invention eliminates undesirable reflected images of the back panel vaguely shown on the front panel when the front panel is on and the back panel is off. A light attenuator, eliminates the reflected images. It decreases the intensity of light emitted from the front panel to the back panel, and is disposed between the back and the front panels or built into the electroluminescent panel, so that the reflected images are eliminated.

摘要： The primary object of the present invention is to provide a touch panel which has an excellent contact level between a undercoat layer and a substrate on which the undercoat layer is formed. The secondary object of the present invention to provide a touch panel which is lightweight and provided with a wide operating temperature and impact resistance. The primary object is achieved by providing a metal layer between a conductive-layer forming member and an undercoat layer, the metal layer being formed from a single metal element or an alloy of metal elements. The secondary object of the present invention is achieved by using an amorphous polyolefine base resin sheet for forming conductive-layer forming members of the touch and display substrates and using a material for forming a supporting member so that a difference between linear expansion coefficients of the supporting member and each of the conductive-layer forming members is kept within 1×10−5/° C.
