Abstract

A system including a display module and a system module. The display module is integrated in a portable device with a display communicatively coupled to one or more of a driver unit, a measurement unit, a timing controller, a compensation sub-module, and a display memory unit. The system module is communicatively coupled to the display module and has one or more interface modules, one or more processing units, and one or more system memory units. At least one of the processing units and the system memory units is programmable to calculate new compensation parameters for the display module during an offline operation.

Claims

1. A portable electronic device comprising:

a driver unit;

a timing controller;

a display memory unit;

an electronic video display communicatively coupled to at least one of the driver unit, a measurement unit, the timing controller, a compensation sub-module, and the display memory unit, each of which uses display resources, wherein the driver unit, the timing controller, the display memory unit, the electronic video display, are all included in a display module carried on a first substrate and integrated in the portable electronic device;

one or more interface modules;

one or more system memory units;

at least one processing unit, included in a system module physically arranged on one or more substrates separate from the first substrate, and configured to execute system level applications of the portable electronic device and, during an offline operation in which the electronic video display is off, to perform calculations, offloaded from or shared with said compensation sub-module, for new compensation parameters for the display module, using system level resources distinct from the display level resources, including using the one or more system memory units; and

a connector cable configured to interface the display module with the system module.

2. The apparatus of claim 1, wherein the measurement unit carries out measurements of pixels of the electronic video display unit using the system level resources or the display resources or both during an inline operation while pixels of the electronic video display are emitting light.

3. A method of operating a portable electronic device including, a driver unit, a timing controller, a display memory unit, an electronic video display communicatively coupled to at least one of the driver unit, a measurement unit, the timing controller, a compensation sub-module, and the display memory unit, each of which uses display resources, wherein the driver unit, the timing controller, the display memory unit, the electronic video display, are all included in a display module carried on a first substrate and integrated in the portable electronic device, one or more interface modules, one or more system memory units, at least one processing unit, included in a system module physically arranged on one or more substrates separate from the first substrate, a connector cable configured to interface the display module with the system module, the method comprising:

executing at the at least one processing unit, system level applications of the portable electronic device; and

during an offline operation in which the electronic video display is off, performing at the at least one processing unit, calculations, offloaded from or shared with said compensation sub-module, for new compensation parameters for the display module, using system level resources distinct from the display level resources, including using the one or more system memory units.

4. The method of claim 3, further comprising:

carrying out, at the measurement unit, measurements of pixels of the electronic video display unit using the system level resources or the display resources or both during an inline operation while pixels of the electronic video display are emitting light.
