摘要： PURPOSE:To efficiently detect an X coordinate by applying voltage pulses to X electrodes in a specific pattern and successively converging a position area in contact with a detector. CONSTITUTION:During a vertical blanking interval coordinate detection circuit 111 supplies data for applying voltages to the X electrodes x0 to xm-1 in the different patterns for respective line periods through a selector 112 to an X electrode driving circuit 103. That is, the X electrodes x0 to xm-1 are successively equalized into line period number multiples 2 and the voltage is applied to the X electrode of the area on a very right side and the X electrodes of every other present area from the area. For instance, the detection voltage of a pen 104 in contact with the X electrode x2 becomes a voltage level higher for the voltage applying pulse of an (N-1)-th line period (m=2N) and detection data become '1'. By making the detection data and bit data successively correspond to each other in the coordinate detection circuit 111, it is detected that the X coordinate is 2.

摘要： PURPOSE:To obtain an excellent display by switching a line select voltage Vgon which does not turn on a TFT in the beginning and then switching the voltage, to a voltage which turns on the TFT after a prescribed period of time later, so that luminance variation and the generation of a bright line are reduced when a line AC driving system is used for a Vcom AC driving system, and thus eliminating the influence of voltage variation upon a voltage impressed to liquid crystal. CONSTITUTION:A line select voltage switching signal 116 generated by a line select voltage switching signal generating circuit 115 switches line select voltages by a power source circuit 117. The line select signal Vgon selected by the power source circuit 117 is outputted to a gate driver 128. The gate driver 128 selects a line where a display is made according to a CL3 clock 113, but the line select voltage VgonL which does not turn On the TFT is impressed so that the influence of an AC point and voltage variation due to a rise in the line select voltage is not exerted.

摘要： PURPOSE:To drive a crystal display device by means of reduced number of parts by storing one horizontal line of display data temporarily, time-sharing the stored data into multiple times, and distributing the data time-sheared and transmitted into a corresponding signal line of a crystal panel. CONSTITUTION:A data conversion means 104 converts serial display data 100 into parallel crystal display data 105. A data shift means 110 takes in crystal display data 105 by means of a shift clock 106 to output as parallel crystal display data 111. A data latch output 112 latches a horizontal line of data simultaneously in synchronous with a latch clock 107 and arranges data at the same horizontal line to produce crystal display data 113. A multiplexer 114 devides one horizontal time in multiple times and outputs them sequentially by a line data selection signal 10. A line data distribution means 116 inputs crystal display data 115 and outputs simultaneously to a signal line 117 to feed the voltage corresponding to image data to a pixcel.

摘要： PROBLEM TO BE SOLVED: To realize high image quality display by arranging a liquid crystal driver on one side of a liquid crystal panel, reducing a mounting area and inverting at a row and to contract circuit scale of a power source circuit by incorporating an alternating current circuit of a reference voltage of liquid crystal drive to the liquid crystal driver in a liquid crystal display apparatus. SOLUTION: Since the display device has a voltage generation means for generating two alternating current reference voltages driving alternating current from an input reference voltage and an alternating current signal and a means for outputting to be converted into a liquid crystal application voltage different in the alternating current drive at each output to the liquid crystal panel from display data, the two alternating current reference voltages and the alternating current signal, the output in the same liquid crystal driver can be made a liquid crystal drive voltage different from alternating current timing.
