A method and system for programming, calibrating and driving a light emitting device display, and for operating a display at a constant luminance even as some of the pixels in the display are degraded over time. The system may include extracting a time dependent parameter of a pixel for calibration. Each pixel in the display is configured to emit light when a voltage is supplied to the pixel's driving circuit, which causes a current to flow through a light emitting element. Degraded pixels are compensated by supplying their respective driving circuits with greater voltages. The display data is scaled by a compression factor less than one to reserve some voltage levels for compensating degraded pixels. As pixels become more degraded, and require additional compensation, the compression factor is decreased to reserve additional voltage levels for use in compensation.

Method and system for programming, calibrating and/or compensating, and driving an LED display

An apparatus for combined capacitance and pressure sensing is described. The apparatus includes a multiplexer () having a plurality of inputs () and an output (F), a touch panel (), and a front end module (). The touch panel includes a layer structure (; FIG.) comprising one or more layers, each extending perpendicularly to a thickness direction, the one or more layers including a layer of piezoelectric material (; FIG.), the layer structure having first () and second (; FIG.) opposite faces, and the layer(s) arranged between the first and second faces such that the thickness direction of each layer is perpendicular to the first and second faces. The touch panel also includes a plurality of first electrodes () disposed on the first face, each first electrode connected to a respective input of the multiplexer. The touch panel also includes at least one second electrode () disposed on the second face. The front end module is configured to receive an input signal () from the multiplexer output. The front end module includes a first stage () configured to provide an amplified signal based on the input signal, and a second stage comprising first () and second () frequency-dependent filters configured to receive the amplified signal and to provide respective first () and second () filtered signals. The first filtered signal has a first frequency bandwidth, and the second filtered signal has a second frequency bandwidth which has a relatively higher start-frequency than the first frequency bandwidth.

Pressure-sensitive touch panel

A pressure sensing architecture for use with liquid crystal (LC), organic light emitting diode (OLED), electrophoretic, or other similarly fabricated displays. The described architecture includes a bottom TFT structure and a top structure with color filter material, and with liquid crystal, electrophoretic or OLED material provided in between. A piezoelectric or equivalent material is provided within the display assembly. Transmitting and receiving electrodes can be used to electrically bias the piezoelectric or equivalent material, which provides an analog electrical signal in response to incident touch pressure.

Pressure sensing display device

A display degradation compensation system and method for adjusting the operating conditions for pixels in an OLED display to compensate for non-uniformity or aging of the display. The system or method sets an initial value for at least one of peak luminance and an operating condition, calculates compensation values for the pixels in the display, determines the number of pixels having compensation values larger than a predetermined threshold compensation value, and if the determined number of pixels having compensation values larger than said predetermined threshold value is greater than a predetermined threshold number, adjusts the set value until said determined number of pixels is less than said predetermined threshold number.

There is provided a system for managing maintenance of a plurality of resources. The system may comprise a computerized maintenance management system configured to track maintenance activities of users across at least two clients. The system may also extract data representing performance or other trends. The system may also enable users to upload information, extract an information set from the uploaded information, generate one or more messages based on the information set, and transmit the messages to clients.

Computer system and method for maintenance management including collaboration across clients

Switching of power modes for touch screens is disclosed. In example embodiments a touch detect mode may be activated for touchscreen operation. The touchscreen may be a projected capacitance screen that includes force sensing based on piezo electric sensors. The touch detect mode may be a low power mode in which at least one channel, but fewer than all channels of the touch screen are monitored. When is determined that a touch event has occurred a switch to a scan mode for touchscreen operation may be performed. Scan mode may be a higher power mode in which all channels of the touch screen are scanned at least for position sensing. The touch detect mode monitoring may be implemented by monitoring the total charge on the at least one channel and providing a voltage signal. When the voltage signal meets predetermined criteria an indication of a touch event may be generated.

The computer system includes one or more tools that (i) track activities of users in connection with the management of resources, (ii) extracts insights from such activities, and/or (iii) enables users to upload information or documents related to resource management to the computer system, such tools enabling the automated suggestion of maintenance actions and/or product or service requirements of platform clients. A range of different intelligent features are provided. The computer system may include a CMMS with intelligent features. A number of related computer implemented methods for managing resources in an intelligent way, and based on collective information and knowledge is also provided.

A method and system for compensation of non-uniformities in light emitting device displays is provided. The system includes a module for estimating degradation of an entire pixel circuit based on measurement of a part of the pixel circuit. Based on the estimation, a correction factor is produced to correct non-uniformity of the display.
