small pixel led display is not harmful to eyesight

Small pixel led displays are welcome in a number of occasions by people of all ages because of its unique high brightness, wide color gamut, high contrast and other advantages, however, the small pixel led display light to human eye bio-security issues have also to be taken into attention. HSTV find an evidence to tell the small pixel led display is not harmful to eyesight, see as below:

Chinese Institute of Metrology took accordance with the existing international standards, measured the bio-security of a p1.67 led display from both the blue light hazards to retina and the thermal hazards, and took comparison with a plasma TV and a LCD TV.
Test results show that, at the same brightness and white field conditions, although the peak brightness of the led display is higher than the other two samples in blue band, but its narrow band characteristics resulting weighted scored retinal hazard index not higher than plasma TV and LCD TV. The retina bio-security measured data has no significant differences between the three displays, the led display measurement results even better than the other two displays.
Whats should be keep in mind is that any display can cause permanent eye damage if keeping long-term view on the screen, thus, no matter what form of display is used, the audiences should pay attention to eye health and maintain good habits with the eyes. Work and rest combined is the best way to protect their eyesight.

How to Distingusih the LED Display Quality

Led display products is getting more and more popular for modern life, how to distingusih the led display quality? HSTV listed the following methods:

1. Flatness
Surface flatness of the display should be within ± 1mm, so as to ensure the display image is not distorted. Partial raised or recessed will lead to the display viewing angle appears dead. The quality of flatness is determined mainly by the production process.
2. Brightness and viewing angle
Indoor full color screen brightness should be 800cd / m2 or more, outdoor full color screen brightness should be 6000cd / m2 or more, so as to ensure the normal operation of the display, otherwise the displayed image can't be seen due to low brightness.
3. The balance effect
White balance is one of the most important indicators of the display. Red, green and blue color science should take in the ratio of 1: 4.6: 0.16 in this way pure white is possible, if the actual proportion of any deviation occurs, the white balance bias. White balance is mainly determined by the quality of the display control system
4.The color reduction
Color reduction refers to the color display of color reduction. Display height should be consistent with the color of the playback source, so as to ensure realistic images.
5. Have mosaics, dead phenomenon
Mosaic refers to appears on the display lit or normally black small four-square, both modules necrosis, connector quality mainly used for the display, but off.
Dead point is steady appear on the display or normally black single point, how good or bad from the die to determine the dead point.
6. Have color
Color refers to the existence of obvious color difference between adjacent modules, transition colors in module units, the color phenomenon is mainly caused by the control system is poor, the gray level is not high, low scanning frequency caused.
