24.4: Optical Sensor Embedded Input Display Usable under High-Ambient-Light Conditions

We have developed a new LCD having optical input function usable under high ambient-light conditions. Sensors having different sensitivities are dispersed in the panel, and a sensor driver circuit to control the sensor exposure time are formed monolithically in peripheral using LTPS technology. These two approaches contribute synergistically to widen the range of ambient light condition available for the input function.

Incorporation of input function into displays using LTPS TFT technology

— A new display in which an input function is incorporated has been developed by using LTPS TFT technology. A new circuit configuration that includes a lateral p-i-n diode with an in-pixel amplifier, an LTPS A/D converter on the periphery of the glass substrate and an external image-processing LSI is presented. The experimental results of two major applications of the image-capture function and touch-panel function are discussed.

New configuration of display device having image capture function suitable for LTPS TFT fabrication process is proposed. In this configuration, LTPS A/D converter integration to the glass substrate and operation to generate higher grayscale bitmap in the image processing LSI are involved.

Low‐temperature poly‐Si TFT‐LCD with an integrated analog circuit

— We have developed a 6-bit D/A converter and amplifier integrated low-temperature poly-Si TFT-LCD in which an integrated signal-line driver is driven by a 5-V power supply. We have employed a D/A converter including a new capacitor array and an original amplifier comprised of serially connected comparators to achieve high accuracy. The D/A converter performs gamma correction using upper significant bits of input data. Control signals for these circuits were generated by the integrated timing circuit. These advances in integration have been achieved for the first time using 3-μm design rule and improved LTPS TFT technologies and provide an advanced display system with lower power consumption, smaller module size, and higher durability.

48.2: Display Architecture Suitable for Multiple Ambient Light‐Sensor Integration Using LTPS Technology

We have developed a new LCD having multiple ambient light sensors (ALSs). Counters and a parallel-to-serial converter are formed in peripheral of the LCD panel, programmable clock drivers for the counters, and data registers to hold output of ALSs are included in a source driver LSI. The ALSs perform well in total showing nonlinear gamma property corresponding to the clock even for the case when one of the sensors is covered by a finger shadow.

43.4: An In‐Cell Capacitive Touch‐Sensor Integrated in an LTPS WSVGA TFT‐LCD

We have developed an in-cell capacitive touch-sensor integrated in an LTPS 7″ WSVGA TFT-LCD. The prototype having 256×150 sensors shows advantages such as smooth operation with no touch force, high position accuracy, multi-touch (10 or more), thin and light LCD module, and thus is suitable for various applications.

50.3: Novel Write‐erasable Input Display with Memory Circuits and Photo‐sensors

We have developed a new conceptual LCD with a memory circuit and a photo-sensor in each pixel. This LCD enables to display a still image in the low power consumption. In addition, direct writing and erasing a character in the LCD are available without calculating coordinates by using a light pen.
