| An electronic device may have a housing. Components such as keys may be mounted in openings in the housing. The housing may include a display housing portion and a base portion that are coupled using hinge structures. The keys may be used to form a keyboard in the base portion of the housing. Sensitive circuitry such as sensitive wireless circuitry may be shielded from electromagnetic interference by shielding the openings with a layer of conductive material. The layer of conductive material may be a metal layer that forms part of a reflector for a backlight structure. The backlight structure may be used to provide backlight for keys in the keyboard. The keyboard may include a support structure having openings through which the backlight passes to reach the keys. The openings may be bridged using conductive paths so that the support structure serves as a radio-frequency shielding structure. | ||||||

| 44 | LOW EMI KEYPAD CIRCUITRY | US13233214 | 2011-09-15 | US20130069805A1 | 2013-03-21 | Hong Chean Choo; Kien Beng Tan; Gee Heng Loh |
| Disclosed is keypad circuitry operable to detect a pressed key while reducing electromagnetic interference (EMI). The keypad circuitry is operable to reduce EMI in two ways: a) reducing the voltage swing occurring at the row circuitry and column circuitry of the keypad, and b) reducing the number of signal transitions by restricting the signal transitions to occurring at the column and row corresponding to a pressed key. By limiting signal transitions to occurring only at the row and column corresponding to a pressed key, fewer signal transitions occur, and thus, less EMI is produced. Additionally, reduced voltage swings at the row circuitry and column circuitry results in reduced EMI. | ||||||

| Architecture for a keyboard that supports the n-key rollover feature, while being compatible with well established, high volume, inexpensive manufacturing techniques. The design is a matrix design that uses resistors at each key rather than diodes, and employs novel circuits which allow any combination of simultaneous key presses to be detected using this resistive matrix. The resistors can be screen printed on the flexible sheets in a manner similar to the conductors. A resistive keyboard matrix employs circuit techniques that eliminate phantom key presses. The resistors can be created by screen-printing carbon ink. Additionally, various implementations of the decoder circuits can be employed to provide the n-key rollover feature on flexible sheets for inexpensive production. | ||||||
