Imaging for Professional Healthcare

IPH-MED series are designed and engineered to meet such stringent criteria for life-critical medical applications where quality healthcare service is of interest. All IPH-MED series are using COJE’s proprietary High Brightness LED BLU delivering outstanding FOS (Front of Surface) performances.

Benefits of High Brightness LED Backlight

COJE developed its own High Brightness LED Backlight Systems that provide many advantages. High Brightness LED BLU still has technical difficulties for it to be used widely because of its heat generation and cost increase. COJE resolved those issues and adopted the High Brightness LED BLU for all of its products.

Better Uniformity

If brightness variation exceeds 15%, then LUT (Look Up Table) at a given brightness level is not applicable to the region whose brightness deviates from a target brightness. Brightness uniformity should be controlled tightly along with DICOM compliance of the display in order to achieve and deliver the best image quality. COJE's medical displays are all equipped with its own High Brightness LED BLU that delivers accurate and reliable images at all times.

Wide Color Gamut

COJE’s surgical displays provide a wider color gamut. Now, with color calibration and adjustment features, the products deliver realistic medical images to the intended users in various fields of applications. COJE's proprietary LED BLU design enables the product to maintain its highest color performance through the full brightness range: no color shift and no brightness change.

Built-In Adaptor

All of COJE’s surgical displays use Built-in Adaptor. It makes the installation much more convenient.


HDMI2.0 In/Out

COJE 4k monitor supports the industry's only HDMI2.0 output. 4K 60Hz image can be displayed on a sub-monitor simultaneously with COJE 4K monitor by HDMI2.0 output.


COJE's proprietary roll switch and select OSD navigation system, a patent-pending, enables users to access various features faster and easier. The products are also equipped with hotkeys to access the most frequently used features such as Power On/Off for customers’ convenience.
