Canon's lineup of 4K and 8K professional reference displays support professionals working on Cinema and broadcasting production sites. Canon has developed a high-image-quality processor and backlight technology to achieve high image quality and precision for these displays and take full advantage of the latest high-performing digital cinema cameras, broadcasting lenses, and professional video equipment. These displays also support the latest technologies, including High Dynamic Range (HDR: a technology that makes it possible to achieve a wider brightness range than the standard dynamic range) technologies.
Unlike consumer televisions and PC monitors, professional displays must be highly precise in terms of their uniform image quality, colors, and brightness. Canon uses its proprietary technologies, based on a commitment to image processor performance, to make possible highly precise processing.
Proprietary Image Processor
One of the most important pieces of equipment on a Cinema or broadcasting production site is a reference display, a device used to check the image quality of the content being produced. Having an image-quality reference device designed based on standards established for Cinemas and broadcasting makes possible the same high level of quality regardless of location.
On video production sites demanding high precision, reference values must be strictly adhered to. Therefore, it is necessary to incorporate into the image processor a flow that includes faithful color reproduction, accurate gradations, and high-precision uniformity and coordinate it with the panel and backlight to achieve optimal screen correction and highly precise aging correction.
Canon has developed a new image processor capable of high-precision processing for its high-resolution 4K and 8K reference displays to ensure the visual expression, quality, and reliability demanded of reference displays. In addition, Canon has incorporated its imaging know-how cultivated over its long history of camera development into its algorithms to achieve a high level of image quality. Canon also thoroughly inspects the quality of each display before shipping, performing a series of highly precise adjustments to ensure that each display achieves the faithful color reproduction, high-precision uniformity, and long-term consistency expected of the company's reference displays.

In preparation for major global events, the Cinema and broadcasting industry has begun to transition from the current HD resolution to 4K and 8K resolution, an advancement that also raises the standards for visual expression.
In addition to high-resolution 4K and 8K formats, such new brightness and gradation technologies as HDR are enabling more immersive viewing experiences. As a result, professional reference displays are also evolving.
Canon's professional reference displays employ a 4K or 8K high-resolution, wide-viewing-angle in-plane-switching (IPS) liquid crystal panel unit that enables the display of high-resolution, high-quality content that meets DCI cinema standards and UHD broadcasting standards.
Canon uses high-purity LEDs for its backlights to achieve a wider color gamut, making possible the reproduction of faithful, rich colors that could not be achieved on older display models.
What's more, due to recent developments in HDR technology, Canon's professional reference displays were among the first in the Video Production industry to support HDR standards (HLG: Hybrid Log Gamma, PQ: ST2084). To achieve high brightness and contrast, Canon's displays incorporate more LEDs than conventional standard-dynamic-range (SDR) displays as well as optimized circuit patterns and boards to ensure consistency even at high brightness levels.

HDR technology makes possible a wider brightness range than SDR. Thanks to Canon's proprietary image processor and backlight designs, the company's reference displays deliver high-definition 4K and 8K images with high brightness and accurate gradations, enabling a level of visual expression in video production not possible with conventional SDR. For example, the details of clouds in a blue sky, which might have been overexposed when using SDR, can be clearly seen when using HDR thanks to its improved overall contrast. In addition, HDR expands not only the range of brightness but also the color volume, or the range of colors that can be expressed. This means that HDR enables reproduction of a wider range of natural colors, making images look more real and three-dimensional. Display firmware also features several HDR functions useful in various types of visual production. These HDR capabilities earned Canon an Engineering Excellence Award at the 2018 Hollywood Professional Association awards.
