摘要： Novel tools and techniques might provide for implementing user interface validation or diagnostics, and, in particular embodiments, for implementing automated forensic artifact reconstruction and replay of captured and recorded display interface streams. In some embodiments, a computing system might retrieve stream data from a database, the stream data having been captured and recorded by a data stream recording system as display data is being sent from an embedded processor of a graphical user interface (“GUI”) system to a display device, without disturbing the display data being sent. The computing system subsequently parses pixel data from the display data, formats the parsed pixel data, reconstructs one or more display screen images based at least in part on the formatted pixel data, then compares each pixel of each screen image or frame of the reconstructed display screen images with each pixel of a model screen image of each corresponding screen image.

摘要： A display drive circuit comprises a timing control module, a source drive module and a polarity selection module. The source drive module is electrically connected to a plurality of data lines. A control signal output from the timing control module is input to the source drive module via the polarity selection module. When the polarity selection module receives only the control signal, the polarity selection module outputs a first control signal, having the same polarity as that of the control signal, to the source drive module. When the polarity selection module receives the control signal and a polarity reversal signal at the same time, the polarity selection module outputs the first control signal, having the same polarity as that of the control signal, and a second control signal, having an opposite polarity to that of the control signal, to the source drive module.
