摘要： A dual-sided electrophoretic display (700) having a first region (701) and a second region (702) is provided. Each of the first region (701) and the second region (702) includes selectively operable members (703,704) that function as pixels for presenting images on the electrophoretic display (700). Each of the selectively operable members (703,704) is driven by a driver circuit (710) by way of corresponding thin film transistors and capacitors (742,742), which are opaque. As the selectively operable members (704) of the second region (702) are bigger than are the selectively operable members (703) of the first region (701), the aperture ratio of the selectively operable members (704) of the second region (702) is greater than in the first region (701) when viewed from the rear side (730). Thus, a contrast ratio of the second region (602), when viewed from the rear side (730) is sufficiently high that text, icons, and characters presented in the second region (602) are legibly visible on the rear side (730).

摘要： 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.

摘要： An X-radiation protection circuit in a television receiver which permits safe operation at higher voltages and beam currents with corresponding increased video presentation brightness without the production of hazardous X-radiation by means of a control loop in which current in the high voltage sweep transformer generates a feedback signal to a conventional shutdown circuit. Excessive transformer current evidencing high electron beam current automatically lowers the turn-on voltage of the shutdown circuit providing for CRT operation at maximum safe high voltage levels and electron beam currents in accordance with "Isodose" safety curves for CRT operation.
