摘要:
A segmented optical shutter (200) is used with a high-resolution display (101) to provide a dynamic user interface (400) for a portable electronic device (100). To reduce optical interference corresponding to a correlation function for transmitted light occurring between the photospacers (209) in the segmented optical shutter (200) and the black matrix (107), the photospacers (209) are disposed along a light transmitting substrate (204) of the segmented optical shutter (200) in a quasi-random arrangement. The quasi-random arrangement, which may include varying the horizontal and vertical placement of the photospacers (209), repeating asymmetrical subsections of photospacer configurations, varying the size or shape of the photospacers (209), or combinations thereof, misaligns the photospacers (209) relative to the black matrix (107) or other elements to reduce optical interference and moiré patterns that may otherwise be perceptible to a user.

An illuminated keypad (400) includes a substantially transparent keypad (420) having a plurality of actuator buttons (412), a plurality of switches (404) residing substantially and correspondingly below the plurality of actuator buttons, a display laminate layer (415) residing between the plurality of actuator buttons and the plurality of switches, and a light source (417) reflectively illuminating a pattern of a symbol on the laminate layer by radiating light through the substantially transparent keypad. The display laminate can include a driver layer (406) having a conductor pattern configured in the pattern of the symbol to be displayed on the substantially transparent keypad, a transparent conductor layer (410), and an electrically active ink layer (408) disposed between the transparent conductor layer and the driver layer.

A transflective color liquid crystal display (200) with internal rear polarizer (275) has a front polarizer (260), a front substrate (210), a first color filter layer (212), a front transparent electrode (240), a liquid crystal layer (250), a rear transparent electrode (230), a rear polarizer (275), a reflector (235), and a rear substrate (220). The inclusion of an internal rear polarizer (275) results in little optical path difference between a reflective mode and a transmissive mode of the transflective color LCD (200). The internal rear polarizer (275) also results in little parallax, because the internal reflector (235) is very close to an image-forming layer (250). Additionally, a second color filter layer (214) can be added behind the internal reflector (235) to enhance the brightness and color saturation of the transflective color LCD (200) with internal rear polarizer (275) during the transmissive mode.

Techniques and mechanisms for providing illumination of a display. In an embodiment, a light guide includes a first portion to receive light, a second portion to output some or all of the light, and a third portion configured to propagate the light between the first portion and the second portion. The third portion forms a first deflection structure which adjoins, and extends between, respective surface regions of the first portion and the second portion. A light source is coupled to provide edgewise illumination of the light guide via the first portion. In another embodiment, the light propagates through the third portion and into a region, between two parallel planes, in which the second portion is located.
摘要:
A method performed by a processor of a electronic device, including rendering (402), on an electronic display, a line segment having a first direction and moving in a second direction. The method also includes a step of determining (404) whether the direction of the line segment (the first direction) is in the same direction that the line segment is moving (the second direction). If the processor determines that the line segment is not moving in the same direction of the direction of the line segment (the first direction), then the processor performs (408) a first action, such as adjusting the color intensity of the line segment. If the processor determines that the line segment is moving in the same direction of the direction of the line segment (e.g., the two directions are substantially parallel to each other), then the processor performs (406) a second action.

Disclosed herein are a plurality of displays for an electronic device including a display layer (102, 104), a light guide layer (108), and a damping material layer (110) coupled between the light guide layer and the display layer. The display layer in one embodiment is a liquid crystal display layer, but other types of display layers may be used. The light guide layer may serve as a back light for the display layer, and may be between approximately 0.05 mm and 2 mm in thickness. Devices described herein include at least one interposed layer of acoustic and/or mechanical energy absorbing material, also referred to herein as damping material, between the display layer susceptible to vibration, and a hard layer near the display layer. The damping material as described herein may reduce the audio noise. The energy absorbing layer may take the form of an audio energy absorbing sheet interposed between layers of the display.
