摘要： A liquid crystal display device having output buffers corresponding to column lines, and comprising analog switches provided between output ends of the output buffers and the column lines respectively, and a switch controller for on-off controlling the analog switches. A DA converter is provided in the preceding stage of the output buffers, and the switch controller turns off the analog switches during a DA conversion period of the DA converter or during a precharge period prior to DA conversion, and turns on the analog switches during a predetermined period other than such periods. The output buffers are disconnected from or connected to the column lines when the analog switches are turned off or turned on. Therefore the output circuit can be separated from a capacitive load by disconnecting the output buffers from the column lines through turning off the analog switches during a DA conversion period of a DA converter provided in the preceding stage of the output circuit or during a precharge period prior to DA conversion, hence preventing increase of the output current of each output buffer while ensuring sufficient change of the signal potential.

摘要： An image pickup device capable of stably detecting an object irrespective of use conditions while reducing manufacturing costs is provided. When illumination light from a backlight 15 is emitted to a proximity object from an I/O display panel 20, an electric charge for charging is accumulated in each of image pickup pixels 33 in accordance with total light amount as a summation of reflected light Lon originating from the illumination light and environment light (outside light) L0. Moreover, when the above-described illumination light is not emitted, an electric charge for discharging is released from each of the image pickup pixels 33 in accordance with light amount of the environment light L0. Thereby, a component by the environment light L0 is subtracted in an image pickup signal obtained from each of the image pickup pixels 33, so object information about the proximity object is obtainable without influence of the environment light L0. Moreover, in a light reception drive circuit 13, a smaller number of necessary frame memories 13A for producing a picked-up image from the image pickup signal than that in related art are necessary.
