From the background information supplied by the inventors, news correspondents obtained the following quote: "The present disclosure relates generally to an electronic display for an electronic device and, more particularly, to an electronic display with bit error rate (BER) detection circuitry.
"This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present techniques, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art.
"Electronic displays, such as liquid crystal displays (LCDs) and organic light emitting diode (OLED) displays, are commonly used in electronic devices such as televisions, computers, and phones. The electronic displays display images when image data is sent by a timing controller (TCON) to display drivers in the electronic display. Conventionally, this image data from the TCON is sent at a sufficiently low frequency such that bit errors are relatively uncommon.
"Chip-on-glass (COG) data links may connect the TCON to each display driver. Many failure modes could occur in the COG data links that could make one the bit error rate (BER) of image data received by some display drivers worse than others. Some failures may be obvious during manufacturing and may be relatively easy to spot. These obvious failures may manifest as screen noise visible to a human operator, allowing manufacturers to discard or repair the electronic display. Latent failures, however, may not at first be serious enough to cause any visible display noise at the time of manufacturing. These latent failures could go unscreened, later manifesting as long-term failures after sale to a user."
Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "A summary of certain embodiments disclosed herein is set forth below. It should be understood that these aspects are presented merely to provide the reader with a brief summary of these certain embodiments and that these aspects are not intended to limit the scope of this disclosure. Indeed, this disclosure may encompass a variety of aspects that may not be set forth below.
"Embodiments of the present disclosure relate to devices and methods for monitoring a bit error rate of an intra-panel data link (e.g., a chip-on-glass (COG) data link) between a timing controller and a display driver. For example, an electronic display according to an embodiment may include a timing controller and display driver circuitry. The timing controller may send test data over a data link to the display driver circuitry. The test data may include a known or predictable stream of data. The display driver circuitry may receive the test data via the data link and detect bit errors based at least partly on the test data.
"Various refinements of the features noted above may exist in relation to various aspects of the present disclosure. Further features may also be incorporated in these various aspects as well. These refinements and additional features may exist individually or in any combination. For instance, various features discussed below in relation to one or more of the illustrated embodiments may be incorporated into any of the above-described aspects of the present disclosure alone or in any combination. The brief summary presented above is intended only to familiarize the reader with certain aspects and contexts of embodiments of the present disclosure without limitation to the claimed subject matter."
