Abstract: An LCD display module uses an ingenious gradient flexible printed circuit to produce a larger and thinner display. The gradient flexible printed circuit connects a driver integrated circuit between a printed circuit board assembly and an ITO circuit on a glass substrate. The gradient flexible printed circuit has a narrow, minor end connected to the ITO circuit and a wider, major end connected to the printed circuit board assembly. Because the gradient flexible printed circuit has different end widths, the gradient flexible printed circuit permits reduced spacing of electronic components in proximity of the narrower minor end. Signaling between the electronic components is improved, and electromagnetic shielding is reduced. The gradient flexible printed circuit also has a smaller dimensional stack, thus allowing for a larger display viewing area and a thinner display.

Abstract: An LCD display module includes a polygon flexible printed circuit to produce a thinner display. The polygon flexible printed circuit connects a driver integrated circuit to a printed circuit board assembly and a glass substrate. The polygon flexible printed circuit has a narrow minor end connected to the glass substrate and a wider major end connected to the printed circuit board assembly. Because the polygon flexible printed circuit has different end widths, the polygon flexible printed circuit permits reduced spacing of electronic components in proximity of the narrower minor end. The LCD display module also includes a shielding can in physical communication with the printed circuit board assembly to reduce electromagnetic interference between the printed circuit board and the polygon flexible printed circuit.

Abstract: A display includes an imaging device with a light source providing a first light emission and a second light emission, and an organic light-emitting diode panel proximate to the light source, wherein the first light emission leaks at an active area of the display device. A light emission barrier blocks the first light emission from leaking at the active area of the display while permitting the second light emission through the imaging device.

Abstract: In some examples, a computing device may include a plurality of components, an embedded controller, and a read-only memory (ROM) to store a basic input output system (BIOS). A display device connected to the computing device may include a display panel and a timing controller. The embedded controller may be configured with instructions to determine that a power-on has been initiated, determine that a particular component of the plurality of components of the computing device has an issue that prevents booting the BIOS, and send a message from the embedded controller to the timing controller. The message may instruct the timing controller to display, on the display panel and before the CPU begins execution, one or more error messages associated with the particular component that has the issue preventing booting the BIOS. In some cases, a logo may be displayed along with the one or more error messages.

Abstract: An information handling system presents visual images at a display that includes a display panel having a capacitive touch detection surface supported by an indium tin oxide layer disposed between a front layer, such as polarizer, and a display cell. To prevent excessive charge build up associated with the capacitive touch detection surface, a conductive ink is applied at the display panel perimeter and interfaced with a ground at the rear side of the display panel. In one example embodiment, a non-conductive ink insulates the conductive ink from the display panel except as desired to transfer excess charge from the indium tin oxide layer. The conductive ink may interface directly with the indium tin oxide layer or indirectly through a second non-conductive ink having greater conductivity than the insulative non-conductive ink.

Abstract: An information handling display presents visual images in a privacy mode that manages visual image brightness with a local processing resource when a predetermined condition is detected, such as multiple individuals in the display field of view. For example, an information handling system provides visual information to a display timing controller that includes a pulse width modulation signal to command display backlight brightness. When in a privacy mode, the timing controller or another processing resource modifies the pulse width modulation signal to command a predetermined reduced brightness, such as in a range of 30 to 50 nits of reduced brightness.

By independently applying a voltage to each electrode, the liquid crystal within each segment can be independently oriented at a desired angle for a particular mode of operation.
