Patent number: 8847895Abstract: A touch panel which is used as an input device for an electronic device, etc., and an electronic device including the touch panel are provided. A touch panel includes a first substrate, and a second substrate spaced from the first substrate by a distance and having a contact surface. A fluid is filled in a gap between the first substrate and the second substrate, and an input button area is delimited due to movement of the fluid when a driving voltage is applied. If a thickness of the gap between the first substrate and the second substrate is reduced below a threshold thickness value in the input button area, the driving voltage is cut off.Type: GrantFiled: March 8, 2010Date of Patent: September 30, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Seong-taek Lim, Sung-hyuk Park, Sung-hee Lee

Patent number: 8847897Abstract: The touch-operating input device is configured so that when the control circuit turns on the main light source corresponding to each of the translucent operation buttons that can be operated, the control circuit, on condition that the translucent operation button corresponding to the main light source that is turned on is operated, turns off the sub-light source corresponding to the translucent operation button that is turned on simultaneously with the main light source. Ease of operation is increased by enabling the operator to distinguish operated translucent operation buttons from translucent operation buttons that have not been operated according to whether or not the main light sources are lit.Type: GrantFiled: February 22, 2010Date of Patent: September 30, 2014Assignee: Toyo Denso Kabushiki KaishaInventors: Naohiro Sakai, Yoshitaka Noguchi, Shigeharu Nezu

Patent number: 8847899Abstract: An input device processing system comprises a sensor module that transmits a first transmitter signal with a transmitter electrode and receives a resulting signal with a receiver electrode. The first transmitter signal comprises a first transmitter frequency, and the resulting signal comprises effects corresponding to the first transmitter signal. A demodulation module demodulates the resulting signal to produce a first signal (e.g., an upper sideband signal) and a second signal (a lower sideband signal), selectably determines a first measurement of a change in capacitive coupling between the transmitter electrode and the receiver electrode based on at least one of the first and second signals, and determines positional information for an input object based on the first measurement.Type: GrantFiled: September 15, 2011Date of Patent: September 30, 2014Assignee: Synaptics IncorporatedInventors: Clyde Washburn, Eric Bohannon, Imre Knausz, Kirk Hargreaves
