A display device can include a display panel having a plurality of pixels disposed on a substrate, and a power supplier configured to supply a driving voltage to the display panel. The power supplier can include a first converter configured to receive an input voltage supplied from an external system and convert the input voltage into a boost voltage, a second converter configured to convert the boost voltage into the driving voltage, a first feedback unit configured to output a first pulse width modulation (PWM) signal to the first converter so that the boost voltage is proportional to a first reference voltage, and a second feedback unit configured to output a second PWM signal to the second converter so that the driving voltage is proportional to a second reference voltage.

Disclosed is a multi-device system running a single operating system, which comprises a first device and a second device. The first device comprises a central processing unit (CPU), a first display unit and a first communication unit. The second device comprises a second communication unit, a microcontroller and a second display unit. The first display unit displays an interface for a first user to operate. Based on the data transmission between the first communication unit and the second communication unit, the CPU, via the microcontroller, indirectly drives the second display unit to display another interface for a second user to operate. According to the operations made by the first user and the second user, the first display unit and the second display unit respectively display different interfaces. From the first user's perspective and the second user's perspective, they are operating two independent operating systems.

An image display system is provided. The image display system includes a host, and a touch controller configured to generate touch event information corresponding to a touch signal and supply the touch event information to an accelerator, wherein the touch signal is output from a touch panel. The accelerator is configured to generate, based on the touch event information supplied from the touch controller, output image data corresponding to a touch event. The image display system further includes a display controller configured to supply the output image data generated by the accelerator to a display panel.

An electroluminescent display apparatus can include a display panel including the one or more subpixels connected to a data line, a gate line, and a low-level power line. The display apparatus can further include a comparator connected to the one or more subpixels through the data line and the low-level power line to compare a first input voltage from the data line with a second input voltage from the low-level power line to generate a comparison output. The first input voltage is a reference voltage, and the second input voltage is a voltage of a specific node of the one or more subpixels capable of being shifted from an initialization voltage.

In a data processing system that includes a graphics processor and a video processor, graphics textures for use by the graphics processor are stored as encoded frames of video data. The video processor then decodes the video frames to reproduce the graphics texture(s) that the video frames encode, and stores the decoded graphics texture or textures in memory for use by the graphics processor.

The graphics processor then reads the decoded graphics textures for use when generating its render outputs, such as output frames for display.

A method of diagnosing connectivity and operational problems between a digital parallel RGB video input device and a digital parallel RGB video display includes transmitting control signals from the input device to the display device, executing the control signals on the display device, generating and transmitting diagnostic signals to a diagnostics processor, and determining if the display is functioning correctly.

This application is directed to a method of managing processing capability of a server system having one or more processing cores that further include multiple processing slices. Upon receiving requests to initiate online gaming sessions, the server system allocates each processing slice of the processing cores to a subset of the online gaming sessions to be executed thereon. A first processing slice is allocated to a first subset of the online gaming sessions including a first gaming session and a second gaming session. At the first processing slice, a time-sharing processing schedule is determined for the first subset of the online gaming sessions. In accordance with the time-sharing processing schedule, the first and second gaming sessions share a duty cycle of the first processing slice, and are executed dynamically and in parallel according to real-time data processing need of the first and second gaming sessions.

An immersive headset device is provided that includes a display portion and a body portion. The display portion may include microdisplays having a compact size. The microdisplays may be movable (e.g., rotational) relative to the body portion and can be moved (e.g., rotated) between a flipped-up position and a flipped-down position. In some instances, when the microdisplays are flipped up, the headset provides an augmented reality (AR) mode to a user, and when the microdisplays are flipped down, the headset provide a virtual reality (VR) mode to the user. In certain implementations, the headset includes an electronics source module to provide power and/or signal to the microdisplays. The electronics source module can be attached to a rear of the body portion in order to provide advantageous weight distribution about the head of the user.
