Aktivmatrix-Flüssigkristallanzeige

The invention relates to an active matrix liquid crystal display with liquid crystal cells arranged in lines and columns, which are located on a common reference potential on one side and gray-scale value signals can be switched on their other side. In order to enhance the voltage range within which the liquid crystal cells can be operated without altering image reproduction, a correction device (28) is provided which distorts the gray-scale value signals (20) reaching the liquid crystal cells (9) on the basis of information regarding the typical dependency between the optical transparency of the liquid crystal cells (9) and the voltage applied thereon and regarding the dependency of the difference in potential between the gray-scale value signals (2) and the reference potential (V0) in such a way that an at least an almost linear relationship between the optical transparency of the liquid crystal cells (9) and the undistorted gray-scale value signals (20') is obtained.

System and Method for Generating and Placing Combination Bets

A method and system for generating and receiving a combination bet may include presenting a plurality of betting events in a display resembling a slot machine. In one embodiment, the user may place a total wager for a combination bet prior to knowing what the betting events are. Placing the bet may spin the reels to randomly generate a plurality of betting events, and success in the combination bet may require that each individual bet is a winner. In another embodiment, the user may be able to spin the reels prior to placing the bet. Betting events still may be randomly generated, but the user may have the ability to select the events on which to wager. Events may comprise in-live sporting events, and the user may have the ability to select various event features, such as the type of events displayed and the odds for each event, in order to customize the betting experience to the user's interests and risk tolerance.

Active matrix LCD

The LCD has a matrix (24) of image points (25) controlled via line and column electrodes (33,35), each of the image points divided into individually controlled sub image points (26,27,28). An image point control device (34) is associated with each image point, for generating different switching signals (44) from the control signal (40) received via the line electrode (35), for providing different grey tones at the different sub image points.

LIQUID CRYSTAL DISPLAY WITH ACTIVE MATRIX

The invention relates to an active matrix liquid crystal display in which picture elements are arranged in lines and columns of a matrix and activated by way of line electrodes and column electrodes. To improve and expand the possibilities for image representation without an increase in the number of lines and columns to be activated, the picture elements (25) are subdivided into sub-elements (26, 27, 28) having corresponding sub- element electrodes (29) which are each connected via controllable switches (32) with the column electrode (33) assigned to the picture element (25). The controllable switches (32) are connected on the control side via a shared picture element control device (34) with the line electrode (35) assigned to the picture element (25). From a control signal (40) supplied to it via the line electrode (35) the picture element control device (34) generates connecting signals (44) which differ in time and place for the different switches (32) such that these sequentially ...

Active matrix liquid crystal display

In an active matrix liquid crystal display having liquid crystal cells arranged in rows and columns. One side of the liquid crystal cells is in contact with a common reference potential and it being possible to switch gray-scale signals through on the other side. In order to increase the voltage range within which the liquid crystal cells can be operated without distortion of the image rendering, a correction device is provided which distorts the gray-scale signals reaching the liquid crystal cell based on information concerning the typical dependence between the optical transparence of the liquid crystal cells and the voltage applied to them and as a function the potential difference between the gray-scale signals and the reference potential in such a way that an at least approximately linear relationship results between the optical transparence of the liquid crystal cells and the undistorted gray-scale signals.

Active matrix liquid crystal display

In an active matrix liquid crystal display, pixels are arranged in rows and columns of a matrix and are controllable via row electrodes and column electrodes. To improve and to expand the possibilities of image rendering without increasing the number of rows and columns to be controlled, the pixels are divided into sub-pixels with corresponding sub-pixel electrodes, each of which is connected to the column electrode assigned to the pixel via controllable switches. On the control side, the controllable switches are connected to the row electrode assigned to the pixel via pixel control unit which is common to them. From a control signal supplied to it via the row electrode the pixel control unit generates locally and chronologically different turn-on signals for the various switches so that they switch chronologically successive different gray-scale levels of a gray-scale signal present at the column electrode through to the sub-pixel electrodes. ...
