The present invention overcomes image defects such as the brightness inclination or smears by reducing the line resistance of a power source bus line which supplies electricity to organic EL elements. A plurality of pixels which are arranged in a matrix array is connected to power source lines, and the plurality of power source lines are connected to a power source bus line. Both ends of the power source bus line are connected to a power source part via a FPC. By supplying electricity to both ends of the power source bus line from the power source part, the line resistance of the power source bus line can be reduced.

A method and apparatus are provided for controlling a digital display device to generate an image for display, wherein the display device is arranged to generate the image as an array of pixels each of a defined brightness achieved by emitting a respective combination of light pulses of durations defined according to a predetermined pulse width modulation (PWM) scheme. Whereas, under conventional PWM schemes, each light pulse would be emitted by the same pixel of a display device, in the present invention rate data from an associated tracker system and data defining predetermined characteristics of the display and operation thereof are used to calculate a pixel displacement in respect of each defined pulse of the PWM scheme. The pixel displacement is used to modify control data defining those pixels to be activated to emit the defined pulse such that a different pixel to that intended emits the pulse during relative movement of the direction of gaze of a user's eye and the display apparatus. This has the effect of reducing unwanted display artefacts during such relative movement which are prevalent in conventional digital display systems.

A control device is a control device that controls, based on an image signal for display of an image for each frame period, driving of a liquid crystal display apparatus, and the control device includes: a period dividing unit that divides a frame period into a first period and a second period later than the first period; a signal calculating unit that calculates, based on the image signal, a first signal value and a second signal value for driving of a liquid crystal element of the liquid crystal display apparatus; and a liquid crystal driving unit that drives the liquid crystal element with the first signal value in the first period, and drives the liquid crystal element with the second signal value in the second period.

A projector system includes a plurality of projectors. The plurality of projectors generates an image based on input video data, superimpose the image, and display a display image. The projector includes a video data processor and a liquid crystal display device. The liquid crystal display device switches the images for each frame and displays the images in a frame-sequential manner. The video data processor includes sub-frame data conversion tables and sub-frame data generators. The sub-frame data generators convert the video data into pieces of sub-frame data based on the sub-frame data conversion tables.

Blanking on a display device (for example, a display monitor or a display panel) in a computer system is avoided by performing a configuration change during the vertical blanking period of a subsequent frame. Upon detecting a change in configuration of one or more display devices in the computer system, a display engine clock phase-locked loop is turned off, reprogrammed to a new frequency and relocked during the vertical blanking period of the subsequent frame.

An electronic display includes a timing controller configured to distribute emission periods throughout an active area of the display over time by generating a plurality of emission clock phases. The electronic display also includes multiple row drivers configured to cause rows of pixels to emit at multiple different emission periods.

A method includes representing dots of an image to be displayed within a field by a digital image code. The field is divided into sub-fields which are further divided into a first and second time interval which respectively comprise a first and a second number of equally long time slots. Time slots are assigned to each bit of the digital image code according to each bit's significance. Successive time slots of the first time interval are assigned to one of the bits of the image code and successive time slots of the second time interval are assigned to a different one of the bits of the image code. Within the duration of at least one sub-field, each rows is selected twice for respectively writing a first bit of the image code during the first time interval and writing a second bit of the image code during the second time interval.

The present disclosure proposes a dual-screen display method for eliminating AR/VR picture tearing and an AR/VR display device, each single screen in a dual-screen for the dual-screen display method being divided into a first half-screen and a second half-screen respectively. The method includes: performing rendering and scanning in parallel for the first half-screen and the second half-screen in unit of half a frame. A start time of scanning the second half-screen is adjusted to eliminate a picture tearing phenomenon.

Systems and methods for programming an electronic display in a double-row manner are provided. A system may include processing circuitry that generates image data and an electronic display that programs multiple rows of display pixels with different pixel data of the image data at the same time. This may allow double-row interlaced driving to reduce or eliminate image artifacts due to intra-frame pauses.
