摘要： A touch panel using an optical sensor has a simple construction and can accurately detect an input position. An illuminating lights emitted from illuminating means are turned into lights having a high directivity in an X-axis direction and in a Y-axis direction of the prism lens sheet and thereafter enter from side faces of a light guide panel as incident lights. The incident lights advance in the inside of the light guide panel toward opposite side faces while being subjected to a total reflection and are received by the optical sensor arrays. When an input pen or a fingertip touches a surface of the light guide panel, the lights are refracted or absorbed at a touched position and hence, a quantity of received lights at the optical sensor arrays is reduced.

摘要： In a conventional display device using light emitting elements, white color cannot be accurately displayed since the luminance of each sub-pixel varies for each color. Therefore, in order to achieve the uniformity in luminance of each sub-pixel, the amount of current or the current density flowing in light emitting elements is required to be changed for each color. In that case, a power source is necessarily provided for each color, thus an external circuit is increased, leading to increase in the cost and power consumption. According to the invention, a variable channel-size MOS transistor is used as a transistor for driving a light emitting element. When a signal voltage applied to a control gate is controlled for each sub-pixel, the amount of current or the current density flowing in light emitting elements can be adjusted and luminance of each sub-pixel can also be adjusted for each color.

摘要： A display method and device obtains advantages of both an analog gray scale method and a digital gray scale method by performing display in multiple display modes. In a display mode-specific video signal generation circuit, an input video signal is output, as an analog value without any change, as a binary digital value, and as a multi-valued digital value. As a result, the display mode changes in a timely manner. Accordingly, a clear image can be displayed. In other words, an analog signal and a digital signal are switched and input to a source driver. In addition, the display device also switches and outputs an analog signal and a digital signal such that the display device can have the advantages of both the analog gray scale method and the digital gray scale method.

摘要： It is an object to provide a display device in which a problem of light leakage from a liquid crystal element in black display is reduced or overcome and the contrast is improved. It is another object to provide a pixel circuit having a function to control a lighting state of a backlight based on each pixel. These objects are achieved by turning off a light-emitting element in display of a black gray scale, and by providing a light-emitting element in each pixel and providing, in a pixel circuit, a function to individually control lighting and non-lighting of the light-emitting element depending on a gray scale to perform display. When a backlight is provided in each pixel, a light-emitting element that is a backlight is turned off when a black gray scale is displayed, whereby reduction in contrast due to light leakage from a liquid crystal element can be prevented.
