Abstract: This disclosure is directed to methods, apparatuses, and systems for providing driving signals to present electronic content on an electronic display. The electronic display may include an electronic paper display that utilizes electronic ink to render the electronic content. An electronic signal can be generated by a display controller to drive individual pixels to a black state, a white state, or a gray state in-between the black state and the white state. In some instances, the display controller can provide a first driving signal to set a pixel to a target state, followed by turning a power off for the display. After a predetermined amount of time, a second driving signal can be provided to drive the pixel to the target state, without changing the target state of the pixel.

Abstract: Techniques for adjusting a brightness of a front that lights a display of an electronic device in response to determining that the display is going to perform an update. Typically, page updates on certain types of displays, such as electronic paper displays, result in a relatively large but rapid change in brightness. Therefore, by increasing the brightness during the relatively dark portion of the update (e.g., when some, a majority, or all of the pixels are in the black state) and then decreasing the brightness back to its initial state upon completion of the update, the overall brightness perceived by the user remains more uniform. Increasing the uniformity of this perceived brightness in turn decreases the jarring affect of the flashing update and increases the experience of the user.

Abstract: According to one or more embodiments of the disclosure, a testing apparatus is provided. The testing apparatus may include a base portion configured to receive a device under test (DUT). The base portion may also include an array of light sensors to measure light leakage from the DUT. For example, the testing apparatus may receive, from the array of light sensors, one or more light intensity measurements associated with light leakage from between a bezel element and a display element along a first edge portion of the DUT. The testing apparatus may then transmit the measurements to a testing computer.

Abstract: Techniques for utilizing different versions of a same font when rendering subsequent portions of a content item. For instance, envision that a user requests to open an electronic book. In response to this request, a display controller may display the first page of the electronic book using a flashing update and, therefore, may display the text using a regular weight of a particular font. However, when the user subsequently requests to turn to the second page of the electronic book, the display controller (utilizing a non-flashing update) may update the display using a version of the same font having a lesser weight. Given that some level of bleeding with likely occur when using the non-flashing update, the lesser weight coupled with the bleeding may result in text that approximates the weight of the text of the first page of the electronic book.
