Embodiment Construction
[0077] Throughout the specification, a light source is specified as comprising one or more light emitting diodes. The invention is however not limited to such electro-optical transducers, but covers all light source types, such as incandescent bulbs or "fluorescent" bulbs.
[0078] exist Figure 1 to Figure 30 , the keyboard contains multiple keys as shown in the figure. However, the invention is not limited to this type of keyboard, but rather, can be extended to keyboards having a single key, keys, buttons, and switches in which the invention can be implemented.
[0079] Throughout the specification, an electrical contact is defined as an electrical contact that makes electrical contact, for example, when a user presses a keyboard key to which the contact is connected. However, the invention can be implemented with all contactor types, such as contacts using conductive rubber, mechanical contacts, touch or non-touch membranes, contacts using optical switches, reactance cha...

Abstract
A display device comprising a light source (630) for back-lighting a display surface (610, 620), a modulating means (640) for modulating at least one physical characteristic of the light source, and at least two filters (612 to 614 and 622 to 624) provided in the display surface and each corresponding to a physical characteristic value modulated by the modulating means and to a message to be displayed on said display surface, wherein said filters are placed on an optical path along which the light rays from the light source travel, and the messages at least partially overlap on the display surface. In certain embodiments, at least two of said filters are placed one on top of the other in the display surface. In other embodiments, at least two of said filters each consist of a set of filters, and the sets of filters are alternately juxtaposed in the display surface. In specific embodiments, the modulating means (640) varies the spectral band of the light reaching the filters (612 to 614 and 622 to 624), and said filters have different spectral bands of transparency.
Description
technical field [0001] The present invention is directed to a display device and display method and a keyboard using the same. It can especially be used in portable electronic devices with several modes of operation, such as telephone and game, telephone and remote control, radio, portable television, portable music player, positioning system, game console, personal digital assistant, Internet access terminal And public displays, such as advertising boards or signs and so on. Background technique [0002] Portable electronic devices are undergoing a process of miniaturization demanded by users and made possible by technological advances. The keyboards of these devices therefore also tend to be miniaturized, which makes them difficult to use: the pitch between two keys has the same dimension as the diameter of a finger, resulting in a large number of data entry errors and / or a very limited number of keys and Entering each symbol involves pressing the keypad several times. ...
