摘要： An induction voltage signal induced at a detection electrode of a detection pen is binarized by a slice voltage "e.sub.s ". The number of pulses existing in the binary signal is counted by a counting device. The resulting count value obtained by the counting device and the number of times of electrode scanning in an x-coordinate detection period or a y-coordinate detection period are compared with each other by means of a comparator. When the number of pulses is greater, an error detection alarm signal is output by an alarm device. Thus the existence of the pulses based on the error detection signal is detected in the binary signal based on the induction voltage signal from the detection electrode to output the error detection alarm signal. The above arrangement allows the coordinates at the tip end of the detection pen to be detected in a stable and correct manner even when external noise is detected.
摘要翻译：在检测笔的检测电极处感应的感应电压信号通过片电压“es”进行二值化。存储在二进制信号中的脉冲数由计数装置计数。通过计数装置得到的计数值和x坐标检测期间或y坐标检测期间的电极扫描次数通过比较器进行比较。当脉冲数较大时，报警装置输出错误检测报警信号。因此，基于来自检测电极的感应电压信号，在二进制信号中检测基于误差检测信号的脉冲的存在，以输出误差检测报警信号。即使检测到外部噪声，上述布置允许以稳定和正确的方式检测检测笔的尖端处的坐标。

摘要： A display screen of an onboard display device is disposed so that a speedometer is displayed in front of a driver of a vehicle. When a right-turn instruction is detected, a blinker is displayed and a rightward rear view image outside the vehicle is displayed on the right side of the display screen. When a left-turn instruction is detected, a blinker is displayed and a leftward rear view image outside the vehicle is displayed on the left side of the display screen. Displaying the image in different positions of the display screen according to the right or the left turn instruction facilitates an intuitive determination of a meaning of the image and makes it easier to drive the vehicle.

摘要： The present projection display apparatus includes an illumination source, an LCD panel including a polarizing plate, a light projecting and receiving combinational lens, a screen, a light pen, a detection-use polarizing plate, a CCD, and a control circuit for controlling an operation of the LCD panel upon receiving a signal from the CCD. The combinational lens throws light of a display image from the LCD panel to project the light on the screen. Meanwhile, the lens receives light from the display image and luminescent spot light from the pen to focus them on the LCD panel and then reflect the same to make them incident on the CCD via the detection-use polarizing plate. The detection-use polarizing plate does not transmit the light of the display image.

摘要： In a coordinate detection period, a first electrode drive circuit sequentially selects source electrodes Sn of the TFT LCD panel to connect the same to an x-signal current amplifying circuit, and to apply an AC voltage to the non-selected electrodes. The x-signal current amplifying circuit detects a detection current flowing through the selected electrode, the magnitude of which corresponds to a distance to a finger (or a conductor pen), to obtain an x-coordinate detection voltage. A second electrode drive circuit and a y-signal current amplifying circuit operate in similar fashion to obtain a y-coordinate detection voltage. A coordinate detection circuit then obtains the x- and y-coordinate values of the designated position based on the x-coordinate detection voltage and the y-coordinate detection voltage, thus enabling pointing by a codeless pen and a finger.

摘要： An M-sequence signal is generated in an M-sequence generation circuit, and the M-sequence signal, which is successively delayed by a column-electrode driving circuit or a row-electrode driving circuit, is applied to a column-electrode group or a row-electrode group. A correlator finds a correlation between the M-sequence signal and a detection signal that has been detected by amplifying electrostatically induced voltage that appeared in the detection electrode of an electronic pen so that a position specified by the electronic pen is detected by a detection circuit as a coordinate signal. Thus, it is possible to obtain a coordinate detection signal having a superior S/N ratio without reducing the coordinate detection speed, and consequently to carry out a coordinate detecting operation with high precision.
