If replacement of the matrix to the new in the case of computer monitors are often not profitable and easier to buy a new monitor, in the case of laptops, it looks very different.
services, associated with the replacement of matrices in external monitors, relatively rare, and the matrix itself or its replacement is usually at a price equal to the cost in the bag you buy a new monitor. In the case of a laptop, even the new generation (gaming), the average market price of the new matrix http://hp-parts.com.ua/ about 50 dollars, and replacement of the matrix itself is worth about 10-15 dollars depending on model and complexity of matrix replacement process. And if your hands are growing from the right place, replace the matrix on a laptop on their own is not difficult, see step by step instructions here. Compared to the price of a new laptop, this type of service will always be profitable..
The situation is relatively simple in the case of, When you middle-class laptop with Led screen. As an example, take the 15.6-inch notebook LED HD 40PIN matrix from flash-matrix. They are produced by several world leading manufacturers, such as HP, Samsung, LG, Chimei Innolux, or BOE. Samsung matrix (LTN156AT05), LG matrix (LP156WH3) Chimei Innolux or (B156HW01), eg, They look the same, and in between the brands you will not find any difference. They are interchangeable and work are compatible with each other.
But what, if we find in the laptop matrix fluorescent lamp CCFL? Logical thinking tells what to look for in the market exactly the same matrix. Unfortunately, often, that the fluorescent matrix is already out of production. It screens were installed on laptops, presented a few years ago the market. Manufacturers switched to using thinner, more energy-efficient and, most importantly, cheaper matrices, eg, Edge LED backlit.
Very rare in the market, you can find a completely new CCFL-matrix, and even if you find a seller with the old product, prices are too high, even doubled compared to the new generation panels. In this case, you need to look b / the matrix, often with significant traces of use, and, Besides, with no guarantee of effective work, and with no guarantee of lifetime. In this case, much more profitable will find interchangeable matrix Led.
How to connect the LED array instead of fluorescent CCFL?
In this case, CCFL converters for Led matrices will help. The adapter allows you to connect the LED matrix (new generation) instead of the old fluorescent. matrix trail, coming out of the motherboard of the laptop, It is a 30-pin. The converter has an input for a belt and a 40-pin connector that enables to connect LED array (40PIN).
Below is a picture of a converter system, which allows you to connect the matrix and an inverter loop. In places, marked by yellow adhesive tape, should rigidly stick to the matrix converter, to facilitate its subsequent positioning and attachment tapes.
The only drawback of this design is the inability of backlighting. illumination level is at the minimum or maximum level. Besides, it should be remembered, that the installation of the LED array to the inverter instead of CCFL CCFL fluorescent matrix is only an alternative to. The method used, when the market is impossible to find a replacement for the original fluorescent matrix or when the cost of CCFL matrix is much higher, than when replacing the LED. Unfortunately, Not all laptops are compatible with this set.
