On-demand, post-production de-mura of a television is described herein. An example system includes a television that comprises a screen and a local de-mura application. The system also includes a mobile device that comprises a mobile de-mura module. In operation, the mobile de-mura module identifies and quantifies mura in the screen of the television for a given IRE index. These operations are repeatedly performed in a measurement loop that iterates over a range of IRE indexes. Raw uniformity data is generated from such iterations. The local de-mura application uses the uniformity data to de-mura the screen and improve gray uniformity performance of the television. Further, the mobile de-mura module and the local de-mura application are configured to fine tune and further de-mura the screen by iterating a verification loop over a range of IRE indexes, wherein operation of the verification loop is substantially similar to operation of the measurement loop.
A system, comprising:
The system of claim 5, wherein the pixel positioning pattern comprises a uniform grid and a plurality of crosses.
A method in a mobile device for post-production de-mura of a screen of a television, comprising:
A tangible computer-readable device having instructions stored thereon that, when executed by at least one computing device in a mobile device, cause the at least one computing device to perform operations comprising:
