LED display brightness level how to identify
Brightness discrimination level refers to the human eye can distinguish the image from the darkest to the white between the brightness level. The gray level of the display mentioned above is very high, can reach 256 or even 1024 level. However, due to the sensitivity of the human eye to brightness is limited, and can not fully recognize the gray level. That is to say that many adjacent levels of gray-scale people may look the same. And the ability to distinguish eyes each person is different. For the display, the human eye recognition level is naturally the better, because the display of the image, after all, is to see people. The greater the brightness level that the human eye can distinguish, the greater the color space of the display, and the greater the potential for rich colors. Brightness discrimination level can be used to test the software, the general display can reach more than 20 even if the better level.
Now some of the domestic control system supplier of the so-called 4096 gray or 16384 level of gray or higher refers to the non-linear transformation after the size of gray space. 4096 is the use of 8-bit to 12-bit space of the nonlinear transformation technology, 16384 is the use of 8 to 16-bit nonlinear transformation technology. From the 8-bit source to do non-linear transformation, the conversion space is certainly greater than the 8-bit source. Generally at least 10 bits. Like the same gray, this parameter is not the bigger the better, the general 12 can do enough to change the.
