摘要： An improved liquid crystal display device of the type having a liquid crystal display panel, a light guide plate below a surface of the display panel and located between a reflecting portion and a diffusing portion, and a light collecting lens located at one end of the light guide plate for collecting and transmitting light to the light guide plate for providing backlight to the display panel. The display device includes a light transmitter located between the light collecting lens and the light guide plate. The light transmitter optically connects the light collecting lens and the light guide plate and separates the light collecting lens from the display panel by a predetermined difference. The light transmitter allows light to be more evenly distributed or reflected onto the display panel so that images displayed on the panel have a more uniform brightness.

摘要： A liquid crystal display (LCD) includes liquid crystal display panel located within a housing. A backlight source is detachably connected to the housing for providing light to the display panel. When the backlight source is removed from the housing, outside light, such as ambient light, provides light to the display panel. The LCD includes a light collecting lens which transmits light to the display panel and which is either covered by the backlight source or exposed to an external light source when the backlight source is detached from the housing. When the backlight source is detached, the LCD has a small size and light weight, making it convenient for carrying and using outdoors. The LCD also consumes less power when the backlight source is detached.

摘要： A liquid crystal display apparatus includes a liquid crystal display panel having preset display characteristics, such as image brightness and contrast. A luminescent unit is optically connected with the display panel and provides light to the display panel in order to form an image on the display panel. The luminescent unit includes a light collector which collects ambient light and a light source, for generating light when the amount of ambient light is insufficient to generate a clear image. A control circuit is electrically connected to the display panel and automatically varies the preset display characteristics in accordance with the amount of ambient light collected by the light collector.

摘要： An analog value storing apparatus comprises a semiconductor field-effect device, including a substrate, a source and drain formed to define a channel region, a floating gate embedded in an insulating layer on the channel region, a control gate connected to the ground on the insulating layer above the floating gate, a write voltage source coupled to the source to supply a write voltage to charge the floating gate, a resistor having a relatively high resistance value inserted between the write voltage source and the source, and an analog value voltage source connected to the drain. As a result, the floating gate begins to be charged with the write voltage and the analog voltage and stops being charged with the voltage at the source determined as voltage division of the write voltage and the analog voltage by the high resistance value of the resistor and the internal resistance value of the device. Preferably, an array of a plurality of such devices is used and an analog signal is stored in the form of a series of sampled analog values sampled from the analog signal at the timing of addressing while such devices are addressed sequentially. The stored analog values are read out while the devices are addressed, whereby and original analog signal is reproduced.

摘要： A semiconductor memory device comprising a composite structure of semiconductor-insulation layer-floating gate-insulation layer-control gate, in which a periphery of said floating gate is formed to extend up to and immediately above at least one of source and drain regions, such that both overlap each other through the insulation layer therebetween of silicon dioxide and of a thickness of 200 to 400A for more than 0.35 microns in length but not exceeding two times the distance between the source and drain regions. In erasing the contents written in the inventive memory device, a voltage is applied between the substrate and at least one of the source and drain regions in a reverse bias direction with respect to a junction therebetween, while the control gate is supplied with the same potential as that of the substrate or grounded, said erasing voltage being selected to a relatively small value sufficient to cause a Fowler-Nordheim tunnel phenomenon through the first insulation layer between the floating gate and at least one of the source and drain regions at said overlapping area.
