Patent number: 9805441Abstract: A method and apparatus for controlling embedded raw image data within a display having internal memory. The method includes sending a frame of code and a final compilation of raw image data to the internal memory of the display from a primary host processor prior to the primary host processor entering a sleep state. When the primary host processor has entered a sleep state, control of the raw image data is redirected to at least one secondary host processor. The secondary host processor reads the frame of code within the internal memory of the display and instructs the display to perform an image-related behavior output that may include updating the display itself based on the frame of code found in the internal memory of the display.Type: GrantFiled: January 7, 2014Date of Patent: October 31, 2017Assignee: Google Technology Holdings LLCInventor: John W. Kaehler

Patent number: 9436970Abstract: In embodiments of display co-processing, a computing device includes a display, a full-power processor, and a low-power processor that can alter visual content presented by the display without utilizing the full-power processor. The low-power processor can, responsive to a request from the full-power processor, generate additional display data to update display data stored in a frame-buffer of the display. The low-power processor can then transmit the additional display data to the frame-buffer effective to alter at least a portion of the visual content presented by the display. In some embodiments, the additional display data is transmitted via a protocol converter that forwards the display data to the display using a display-specific communication protocol.Type: GrantFiled: March 7, 2014Date of Patent: September 6, 2016Assignee: Google Technology Holdings LLCInventors: Nathan M. Connell, Christian L. Flowers, John W. Kaehler, George B. Standish

Publication number: 20130278539Abstract: A method and apparatus for testing a capacitive touch screen of a touch panel as commonly implemented on mobile and other electronic devices (or another touch-sensing device) are disclosed herein. In at least some embodiments, the method involves placing the touch screen in relation to a photoconductive panel (for example, a panel made from Cadmium Sulfide) so that the device and panel are adjacent to one another. Then, the panel is illuminated in a known manner, for example, by way of an image displayed on a display of the touch panel. Further, upon illumination of the panel, the panel conducts in a manner correlated to the illumination. Due to this conducting, capacitance change(s) occur that should actuate the touch screen in a corresponding manner. The capacitance change(s) detected at the touch screen can be compared with the known illumination pattern to determine whether the touch screen is operating properly.Type: ApplicationFiled: April 20, 2012Publication date: October 24, 2013Applicant: Motorola Mobility, Inc.Inventors: Mark F.

Publication number: 20090079707Abstract: Disclosed are touch screen devices and methods of sensing an object near the surface of a touch screen device. A capacitive sensor is integrated into display electronics by flipping the traditional thin film transistor liquid crystal display (TFT) stack-up which has a bottom gate structure so that it is an inverted bottom gate structure. Accordingly, the gate structure is near the top of the display and the gate drive lines are re-used as excitation lines in addition to their function as display lines. The excitation lines therefore drive excitation to generate an induced electric field at the surface of the display device. Additionally, other lines are used as sensor lines so that sensor signals are input to the device controller to determine the position of an object at the surface of the display device. Accordingly, the excitation lines are scanned to detect the presence of a finger or other object.Type: ApplicationFiled: September 24, 2007Publication date: March 26, 2009Applicant: MOTOROLA, INC.Inventors: JOHN W.
