    摘要: It is an object of the invention to provide a display device which performs high grayscale display in accordance with display contents and a game machine with an improved realistic sensation. The invention is a display device characterized by including a pixel portion which performs display based on a video signal and a driver circuit portion inputted with the video signal, wherein the driver circuit portion has a unit for controlling a grayscale in accordance with display of the pixel portion. In a liquid crystal display device, luminance of a lighting unit is controlled based on a signal from the unit for controlling a grayscale whereas a current supplied to a light emitting element is controlled in a light emitting device. By applying such a display device to a game machine, a realistic sensation can be improved.

    摘要: A display device in which the current load of wirings are distributed and display variations due to voltage drop are suppressed. An active matrix display device of the invention comprises a first current input terminal, a second current input terminal, and a plurality of current supply lines extending parallel to each other. Each current supply line is connected to a plurality of driving transistors in a line. One end of each current supply line is connected to the first current input terminal via a first wiring intersecting with the current supply lines, and the other end thereof is connected to the second current input terminal via a second wiring intersecting with the current supply lines. Accordingly, a current is supplied to each current supply line from both the first and the second current input terminals. The first and the second current input terminals are provided separately from each other.

    摘要: A display device with high-definition, in which display unevenness due to a voltage drop in a wiring or display unevenness due to a variation in characteristics of TFTs are suppressed. The display device of the invention comprises a first wiring for transmitting a video signal and a second wiring for supplying a current to a light emitting element. The first wiring and the second wiring extend parallel to each other, and are formed so as to overlap with each other at least partly with an insulating layer interposed therebetween.

    摘要: To provide a display device whose display can be recognized even in dark places or under the strong outside light. The display device performs display by controlling the number of gray scales in accordance with the intensity of outside light, which means a display mode can be switched in accordance with the data to be displayed on the display screen. A video signal generation circuit is controlled in each display mode in such a manner that it directly outputs an input video signal with an analog value, outputs a signal with a binary digital value, or outputs a signal with a multivalued digital value. As a result, gray scales displayed in pixels are timely changed. Accordingly, clear images can be displayed while maintaining high visibility in various environments, in the wide range from, for example, dark places or indoors (e.g., under a fluorescent lighting) to outdoors (e.g., under the sunlight).

    摘要: The present invention provides a semiconductor device in which a power line is not affected by noise due to a voltage drop caused by instantaneous high-current consumption in the buffer portion and that has no possibility that a logic portion malfunctions. In a case where the same potential is supplied to a logic portion and a buffer portion, by a method in which separate FPC terminals are used for the logic portion and the buffer portion, or by a method in which the FPC terminal is shared but a power line is branched for the logic portion and the buffer portion at a point close to the FPC terminal, a problem that the logic portion is affected by noise generated by a voltage drop of the power line due to instantaneous high-current consumption in the buffer portion can be prevented.
