▎ 摘 要
NOVELTY - The device (11) has a flexible display for displaying images in first and second touch areas, where the first touch area is configured to rotate with respect to the second touch area along a folding axis. Multiple first and second column electrodes are respectively integrated into the first and second touch areas. Multiple row electrodes are integrated into and extended across the first and second touch areas. Multiple drive-sense circuits are operated to drive sensor signals on the first column electrodes, the second column electrodes and the row electrodes. A processing module is coupled to multiple drive-sense circuits. The processing module senses electrical characteristic of the row electrode, the first column electrode or the second column electrode based on the sensor signals. The processing module determines proximal touch to the first touch area or the second touch area based on the electrical characteristic. USE - Computing device for processing sensor signals from a sensor to determine a touch on a touch screen of an electronic device such as a cellular phone, a laptop, a tablet, an e-reader, a personal computer (PC), a workstation, a video game device, a server and a television, utilized at in-home automation to industrial systems, health care and transportation facility. Uses include but are not limited to bodies, automobiles, airplanes, boats, ships, trucks, motorcycles, cell phones, televisions, touch-screens, industrial areas, appliances, motors and checkout counters. ADVANTAGE - The device reduces power consumption so that manufacturers can offer better image qualities without affecting battery life, allows a touch screen circuitry to utilize low voltage signal, thus reducing power requirements and adverse effects of cross-coupling between multiple wires, utilizes a common frequency component by the drive-sense circuit for self-capacitance measurements and different frequencies components for mutual capacitance measurements, employs higher frequencies to detect folds and rolls of flexible displays while lower frequencies are employed to detect touches in touch areas of the flexible displays by avoiding interference between the touch detecting signals and the fold detecting signals, and decreases effective mutual capacitance to increase impedance at a given frequency when finger capacitance is effectively in series with the mutual capacitance of sensor layers. DETAILED DESCRIPTION - The flexible display is an organic light-emitting diode (OLED) display or an active matrix organic light emitting diode (AMOLED) display. The flexible display is made of a flexible glass, a flexible metal or a flexible plastic. The first column electrode, the second column electrode and the row electrode are formed of a substantially transparent metal, graphene or indium tin oxide (ITO). DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of an electronic device having three separate touch screen displays. 11Electronic device 17First touch screen display
