Abstract:
A touch control keyboard includes a plurality of keycaps, a plurality of touch key parts, a plurality pairs of conductive distributions, a first circuit board, and a second circuit board. An upper part of each keycap includes a touch key part having a coupling capacitor. The touch key parts and the pair of conductive distributions and the first circuit board are electrically connected. The first circuit board detects the coupling capacitors of the touch key parts by using the pair of conductive distributions to generate a first key signal. The second circuit board detects keystrokes of the keycaps to generate a second key signal.

Abstract:
La présente invention concerne un capteur tactile multicontacts comportant une couche d'interaction déformable élastiquement (10) et une couche support (11), la couche d'interaction (10) présentant à sa surface inférieure un réseau de pistes conductrices (12), la couche support (11) présentant à sa surface supérieure un réseau de pistes conductrices (13) non parallèles au réseau de pistes conductrices (12) de la couche d'interaction (10). Les couches d'interaction (10) et support (11) sont séparées par une première série d'entretoises rigides isolantes (14). Une deuxième série d'entretoises conductrices (15) est disposée au contact d'au moins l'un des deux réseaux de pistes conductrices (12,13). L'impédance et les dimensions de ces entretoises (14) de deuxième série sont déterminées pour empêcher le contact au repos et permettre l'entrée en contact local lors d'une déformation de la couche d'interaction (10), entre les entretoises (15) de la deuxième série et le réseau de pistes conductrices de la couche opposée auxdites entretoises (15) de la deuxième série. La présente invention concerne égalementun contrôleur d'un tel capteur, un écran tactile multicontacts comprenant un tel capteur et un clavier comprenant un ensemble de touches discrètes constitué par un tel capteur.

Abstract:
An environmentally protected keyboard display and input device which may be utilized in conjunction with a variety of digital control systems such as automated bank tellers or building security systems. The keyboard display and input device includes a unitary, transparent flexible keyboard (16) having thickened portions forming keys (36). The keyboard forms an environmental seal including a peripheral gasket to protect an underlying, transparent, pressure sensitive switching assembly (18), which, in turn, overlies a corresponding visual display (24) of alphanumeric characters which indicate the significance of the individual pressure sensitive switches and corresponding keys overlying each character. Pins (66, 68) are formed on the underside of the flexible keyboard (16), below each key (36), to focus and concentrate pressure exerted on each key to the corresponding presure sensitive switch below. An optical grid (22) is provided to restrict the viewing of the alphanumeric characters to the user of the device, to prevent compromising the data input.
Abstract:
Improving the accuracy of input is desired for touch panels, but is difficult to attain by using existing transparent electrode films. The formation of a transparent conductive film constituted of an oxide film having a particular composition comprising indium (In), zinc (Zn), titanium (Ti), and oxygen (O), or a transparent conductive film constituted of an oxide film having a particular composition comprising indium (In), zinc (Zn), titanium (Ti), gallium (Ga), and oxygen (O) on a transparent substrate has enabled the provision of touch panels having improved input accuracy.
Abstract:
An in-mold molding touch module includes a plastic film, a touch circuit and a molding rind. The plastic film includes an inner surface and an outer surface for handling and touching. At least one region of the inner surface and a corresponding region of the outer surface define a touch area. The touch circuit is arranged on the inner surface in the touch area. The molding rind is integrated on the inner surface by an in-mold injecting mode to contain the touch circuit for forming a one-piece body. In addition, the invention also provides a method for manufacturing an in-mold molding touch module.
Abstract:
A touch screen assembly includes a first outer layer (102) and a second outer layer (110) separated by a separator layer (118). The first and second outer layers are transparent, and the separator layer has openings (120) at button locations where buttons will be defined. On each of the outer layers is a layer of transparent conductor (104, 112). On the first outer layer the transparent conductor is in the form of a contiguous trace or path. The touch screen assembly is placed on a display element (203) and images displayed on the display element can be seen through the touch screen assembly. Images such as characters are displayed at button locations, and when a user presses on one of the images the conductive layers on the first and second outer layers of the touch screen assembly come into contact.
