In various embodiments, a computer-implemented method includes determining a size of a display area of a display panel on which one or more images are being displayed, determining a threshold current value based on the size, measuring a first current drawn by the display panel, determining whether the first current exceeds the threshold current value, and upon determining that the first current exceeds the threshold current value, causing a second current providing power to a light source associated with the display panel to be shut off.

Detection of a malfunctioning display using power measurement

In various embodiments, a computer-implemented method comprises measuring a current drawn by a display panel, determining whether the current exceeds a threshold value, and upon determining that the current exceeds the threshold value, causing a light source associated with the display panel to shut off.

Embodiments of the present disclosure set forth techniques for mitigating ghost images in a heads-up display. A computer-implemented method includes generating content for display on a heads-up display system, inserting into the content a version of a display element, wherein the version of the display element comprises one or more visual characteristics configured to reduce a perceivability of a ghost image of the display element, and causing the content, including the version of the display element, to be displayed by the heads-up display system.

Ghost image mitigation for heads-up display

Embodiments are disclosed for a method for controlling backlighting of a heads up display of a vehicle. In one example, the method includes adjusting different backlighting regions of the heads up display differently without analyzing a displayed image. In another example, different backlighting regions include a first region and a second region that do not overlap, and adjusting is based on a vehicle operating parameter, user input, and/or a vehicle mode. In another example, backlighting is controlled via a backlight with an array of light emitting elements, and regions include separate adjacent groups of light emitting elements.

Heads up display

A laser projector includes a drive signal generation unit for processing an input image signal to generate a laser drive signal and a scanner drive signal, a pixel position detection unit for detecting positions of pixels corresponding to a one-frame image from the generated scanner drive signal, a compensation value decision unit for deciding a brightness compensation value corresponding to the detected pixels, a compensation unit for compensating a laser drive signal corresponding to the detected pixels according to the decided brightness compensation value, a laser light source for generating laser light according to the compensated laser drive signal, and a scanner for scanning the laser light according to the scanner drive signal.

Laser projector and method of compensating brightness of the same

An image projection module, a mobile device including the image projection module, and a method for operating the same are disclosed. A method for operating a mobile device including an image projection module includes splitting an input image into a left-eye image and a right-eye image in a three-dimensional (3D) image display mode, driving left-eye and right-eye light sources for outputting light having different wavelengths based on the left-eye image and the right-eye image, synthesizing light output from the left-eye light source and light output from the right-eye light source, and projecting the synthesized light in a first direction and then a second direction. Therefore, it is possible to conveniently display a three-dimensional (3D) image.

Image projection module, mobile device including image projection module and method for operating the same

There is disclosed a laser projector and a method of processing a signal thereof. The laser projector includes a plurality of laser sources configured to generate lasers, a controller configured to control each of the generated lasers to be incident on a specific region of a screen with a time difference, and a scanner configured to scan each of the lasers on the screen.

Laser projector and method of processing signal thereof

A projector and an apparatus and method for driving an optical scanner are disclosed. A sensing signal processor receives a sensing signal that represents sensing of operation of the optical scanner and generates a horizontal scan signal corresponding to a horizontal frequency of the optical scanner on the basis of the received sensing signal. A driving signal generator generates at least one of a horizontal reference signal including line information that indicates the number of horizontal lines of a horizontal driving signal of the optical scanner, a reference clock signal and a scanner driving signal for driving the optical scanner on the basis of the generated horizontal scan signal.
