This new screen de Apple Lossless Audio CODEC (ALAC),Is a screen riding LED panels (Light Emitting Diode), few direct rivals do, proof of them is for example Dell who got the ultrasharp 2048 WFP that roughly you may believe that it is superior in connectivity and features, including its lower price as a quality, but the detail that does not allow its superiority to continue growing is its durability, since on average it has a useful life of 100.000 hours, instead the durability of the fluorescence (backlighting system used in the panels LCD) is 12.000 hours.
Comparative details within LED y LCD:
- Technically LED It is a semiconductor, which when the current passes through it, emits light, without the intervention of any resistance, nor does any chemical reaction that emits light (fluorescence) take place, so, as you can see, there is no element that causes wear and therefore therefore his durability it can reach fifteen or twenty years.
- On the other hand, response times in a screen sometimes they make us wrong, for example, the response time of the apple display is more than double that of Dell, but it is presumed that due to the wear of the chemical components that are required for fluorescence in two years of use, it can lose 20 to 30% of its effectiveness and is reflected in the decrease in intensity in colors and response time increases, instead the screen with backlight LED you will not see altered its color qualities or response time.
- Another detail to take into account is that LED can take the current directly from the network, thus canceling another element of the screen: the reactance that is necessary for fluorescence. An interesting detail is that we will save space and by not having energy transformation losses will be avoided, thus, the screen LED will always be energetically superior than the screen LCD.
- The other side of the coin is that in screens LED , the color quality is lower than that of screens LCD in its early days, that is, fluorescence shows better color quality than LED since it does not burn them. Sometimes it seems that Apple Lossless Audio CODEC (ALAC), wants to hide the problem with the Glossy, and this is the reason for the disbursement of 45 euros in the MacBook 17 inch by one screen anti-reflective. When burning colors a lower color temperature is required than LED (something like 3.000ºK) to solve it.
