Medical SDI monitor is a high-end display device with high clarity, high brightness and high stability in the display field.
With the increasing maturity and popularity of PACS technology, as well as the rapid development of various digital imaging equipment, medical SDI monitor is a terminal image presenter for doctors to realize the observation and diagnosis of patients, and is used to display black and white, color images or text display equipment has what difference?
Taking liquid crystal monitor as an example, it is compared from three aspects: technical parameters, function and safety certification.
General display
01 Technical Specifications
① Size:
Measured in diagonal length, usually in inches.
Medical: basically similar to X film, common sizes: 21.5 “, 24 “, 27 “, 31 “, 32 “, 55”
Common: Common size: 21.5 “, 23.8 “, 28 “, 31.5 “;
② Resolution:
The number of pixels actually displayed per unit area. 1MP=1 million pixels
Medical: 1MP (1024×1280)
2MP (1200×1600)
3MP (1536×2048)
5MP (2048×2560)
10MP (4096×2560)
Common: 800×600, 1024× 768,1280 ×1204
③ Brightness:
Brightness is how bright the image is on the display, in units (cd/m2) candelas per square meter
Medical: 600-700 cd/m2 standard calibration set brightness between 400-500 cd/m2; It requires that the brightness value remain unchanged for 30,000 hours, or even 100,000 hours.
Common: 200-300 cd/m2 No special requirements
④ Contrast:
Describes the difference between the display of black and white, expressing the ratio of the display’s brightest and darkest values, contrast is also called dynamic range.
Medical: 600:1– 1000:1
Common: 300:1– 400:1
⑤ Grey scale:
It reflects the level between black and white images, which is a very important feature of black and white medical images. Gray scale display requires a dedicated graphics card
Medical: 10bit -1024 grey scale, 10bit or 12bit (1024- 2048 grey scale)
Common: 6bit-64, 8bit-256 gray scale
⑥ Viewing Angle
Medical: Up and down/left and right can achieve 178° ultra-wide viewing Angle
Common: up and down Angle of view 140°, left and right Angle of view 160°
⑦ Response time:
Refers to the reaction speed of the liquid crystal display to the input signal display image, that is, the reaction time of the liquid crystal from dark to bright or from light to dark. It is usually calculated in milliseconds (ms)
Medical: For some dynamic high-definition images, it is generally about a few milliseconds, and the requirements for static images are not high
Normal: about 16-5ms
Medical SDI monitor VRS-M2201SD-W, 21.5-inch, LED full HD 1920X1080, brightness 300cd/㎡, aspect ratio 16:9, contrast ratio 1500:1, suitable for hospital operating rooms, surgical centers, clinics, doctors’ offices and similar medical environments.
