INCELL are Chinese-made screens with a high color gamut, INCELL structure, and a predictable quality. JK – FHD The Full HD resolution combines the advantages of 720p with the advantages of 1080i. The Full HD image, called 1080p, has both the refresh rate of 720p and the richness of detail of 1080i. However, twice as much bandwidth is required to send Full HD material as HD material. INCELL means the touch function in the LCD. Touch and screen in one, standard LCD touch on the glass (oncell). ZY - HD HD stands for High Definition and has a slightly lower price and resolution. Since HD is still relatively new, the performance is not quite as well developed as with Full HD. Please make sure that the new screen is made by the same manufacturer as the old one. If it is not, you can easily make the new screen compatible with the phone by copying the code from the old screen. Note! The flexcable for INCELL screens are more fragile than for example original that has 4 layers. It's very important to be careful when installing, if you bend flex to much touch issues might occur. So please be careful during the installation.
