On Ali sold Ledovsky lights, can look in her direction.
I already wrote in the campaign against illiteracy, which is light. LED backlight, which is sold in China, I have long enjoyed, but the fact is that it is designed to replace the lamps only in a matrix with EDGE illumination, ie which is located at the ends of the fiber matrix. A light guide - a thick sheet of Plexiglas. On its surface coated matte points of different diameter. At the edges of the point of the small and rare, to the middle of the fiber - their diameter is greater than the density increased. Thus it is achieved the uniformity of illumination throughout the matrix plane. Light guides have matrices with one lamp (LED stripe) differ from those two is the order of application of these points.
A large-scale television matrix with the CCFL has never been EDGE, only DIRECT (i.e., backlight throughout the entire plane).
The uniformity of LED direct illumination is ensured by the correct location of the light sources and the corresponding design and processing of the reflector. So replacing CCFL direct with LED direct is not an easy task. My case ishere
Shl. For these cases, I have a few rolls of tapes in stock - the last time I took at all was 210 rub / roll. That's just for this tape you need an adjustable voltage regulator driver, not a current.

But can not my exotic matrix have another resolution, for example 1280 * 720?
No, he can not. Otherwise there would not be a correct picture. And there would be a completely different interface connector.
So this matrix is вЂ‹вЂ‹not at all exotic.Post has been editedBoris-leo - 27.07.16, 13:35
