摘要： A touch-sensitive light guide film has an emitting layer, a light guiding layer, a flexible transparent layer and a light source. The emitting layer has a first circuit. The light guiding layer located on one side of the emitting layer has a second circuit and a receiving space. The receiving space is concavely or thoroughly disposed on the light guiding layer. The flexible transparent layer disposed between the emitting layer and the light guiding layer, has a through hole and a receiving hole. The through hole is relative in position to the first circuit and the second circuit, and in the through hole, the first circuit and the second circuit may contact when the flexible transparent layer is compressed. The light source is disposed on the emitting layer and penetrating the receiving hole and protruding into the receiving space.

摘要： A key device includes a bottom plate, a light guiding membrane switch, and a keycap. The light guiding membrane switch is disposed on the bottom plate and includes a lower membrane layer, an upper membrane layer, a light guiding spacing layer, a reflective layer, and an adhering layer. The upper membrane layer is disposed above the lower membrane layer and farther from the bottom plate than the lower membrane layer. The light guiding spacing layer is disposed between the lower membrane layer and the upper membrane layer and includes opposite upper and lower surfaces. The reflective layer is securely fastened on the upper surface. The adhering layer is adhered between the reflective layer and the upper membrane layer, and a position and a shape of the adhering layer correspond to a position and a shape of the reflective layer.

摘要： A mobile terminal keyboard comprises a keyboard body and a key, where sidewalls of the key can produce a cavity so as to form a capsule structure. The keyboard body and the sidewalls can be made of a transparent material; and transparent liquid can be included in the cavity. The mobile terminal keyboard can be convenient for a user and humanized. Light can pass through the transparent liquid in the cavity from one or more directions and generate refraction to form a colorful effect. The liquid in the cavity also can be deformed to generate various color changes on the press of a key.

摘要： A key switch arrangement is able to accomplish the compatibility with a normal keyboard in respect of profile without increasing the height of the keyboard and reduce the cost without adding new members for a light source. The key switch arrangement includes a key-top having an optically transparent key-top having a cutout letter part formed thereon, an optically transparent membrane sheet having a contact, an optically transparent plate member arranged under the membrane sheet, and a light source arranged in the membrane sheet. The light source emits light to pass the plate member and the membrane sheet to illuminate the cutout letter part on the key-top.

摘要： Two transparent conductive panels are separated by a perimeter of elastic adhesive that forms a sealed gap in which transparent insulative fluid is interposed. The fluid has a refraction index close to that of the panels to improve light transmittance through the device. The small width of the gap improves response time and prevents formation of a vacuum in the gap. The panels are connected to a position detection circuit that determines coordinate position of an applied pressure point. Spacers in the gap reduce the chance of accidental large-area contact which would result in an erroneous position command. The elasticity of the adhesive and the small gap width provide better temperature variation tolerance in addition to improved consistency and reliability of operation.

摘要翻译： 两个透明导电板由弹性粘合剂的周边分开，形成密封间隙，其中插入有透明绝缘流体。 流体的折射率接近面板的折射率，以提高通过该装置的透光率。 间隙的小宽度改善了响应时间并且防止了间隙中形成真空。 面板连接到确定所施加的压力点的坐标位置的位置检测电路。 间隙中的间隔减少意外的大面积接触的机会，这将导致错误的位置命令。 粘合剂的弹性和小间隙宽度提供了更好的温度变化公差，同时提高了操作的一致性和可靠性。

摘要： An apparatus front panel has a mechanical user interface in the form of a mechanically controllable regulation and setting elements on the face of the front panel. The front panel is manufactured at least in part from a transparent material in which electrical conductors and components are arranged in order to electrically connect the controllable regulation and setting elements from the face of the front panel with the electrical equipment present in the apparatus via a front panel connection. The front panel is constructed so that it can be attached at least in part to a substantially flat indicia-bearing element such as in front of a screen, in front of a display, or over a printed base or the like.

摘要： Fine particles, of predetermined composition and sized to be within a predetermined size range, are deposited on, and thereafter adhere in random distribution to, one of two adjacent surfaces, serving to keep the surfaces uniformly spaced apart except when an external force causes them to make local contact. The particles are conveniently applied in the form of a spray of a suspension of particles and a fluid carrier material, preferably water with alumina particles, or an aqueous solution of a chloride salt of an alkaline earth metal such as calcium, potassium or sodium when small glass beads are used as the particles. Brown alumina particles (approximately 96% Al.sub.2 O.sub.3) in the size range 3-50 microns, so utilized, are found well suited as parallel surface spacers in optically transparent touch sensitive overlay (TSO) panels. Particle distribution densities in the range 300-1,000 particles per inch are satisfactory for TSO panels, with the higher particle density requiring a higher actuation pressure to be applied.

摘要： The see-through coordinate input tablet is formed of two oppositely facing elements each made of a transparent substrate provided with fine metal wires running in parallel on the inward surface of the substrate, the running directions on the two substrates being perpendicular to each other. At least either one of the elements is provided with a detecting resistor along a side periphery crossing the end portions of the parallel-running metal wires so that the accuracy and reliability in the detection of the coordinates of the inputted point can be improved.

摘要： A custom prototype membrane switch panel, kit, and method for construction. Two membranes, an insulative spacer for use therebetween, and a plurality of conductive elements disposable between each membrane and spacer are provided. Spacer apertures in registry with the elements permit electrical contact therebetween upon displacement of one membrane toward the other. The elements are comprised of conductive ink bonded to an insulated backing in any desired geometric shape or shapes, and may be provided individually or plurally in sheet form separable therefrom for disposition between the spacer and membranes. Elements of different colors facilitate tracing different conductive paths created thereby in the resultant switch panel, and the backing automatically electrically insulates crossovers between the elements. One or more of the membranes or spacer has features, alone or in combination, of transparency, having a graphic grid network superimposed thereon, or being hingable to one or more remaining membrane or spacer, facilitating aforementioned registration.
