The original intention of writing this article is because too many customers don’t understand the various qualities from mysterious China. In order to let our customers clearly know the iPhone, Samsung and Huawei screens from Huaqiangbei. For other brands spare parts, please contact our customer service.
For iPhone lcd display assembly
First we have to know: 5G, 5S, SE, 6G, 6P, 6S, 6SP, 7G, 7P, 8G, 8P and XR are LCD displays. iPhone LCD structure is IN-CELL (touch function film and LCM Module panel are integrated). The touch function layer cannot be manually separated.
X, Xs, Xs Max with OLED display, OLED quality does not require a backlight module, thinner, the touch function layer also can not be separated.
1.Aftermarket quality — Production by Aftermarket Factory. TM (Tianma), YD (Youda), JDF (JingDongFang), LT (Longteng, SC (ShenChao)
Price is the cheapest of all quality. Final good yield depends on each supplier, but the price is very different from the original. At present, the best sales in the market are the quality of TM series (HQ-ESR). The display color is also the closest to the original. However, touch function sensitivity and 3D touch function are slow response. The quality of Aftermarket sold by AMOGSM is the most stable from the original YD factory, the final good yield is as high as 99%, and the supply chain stable.
2.Semi Original — Original dispaly glass (including LCM and touch function film) bonding with flex cable by aftermarket. Also replace front glass lens with frame.
Semi original is the cheapest in all original quality. Except for Display glass, other parts like the quality of the connect flex cable, cable IC controller, front panel glass with frame, backlight assembly can be customized. If the final good yield lower than 97%, it is use of inferior cable, even the backlight is also copy quality.
3.Original Refurbish — Only change front protective panel with frame.
Most manufacturers replace copy backlights to save costs, but in fact the quality of the refurbishment is limited to replacing the front panel, so you must be clear when you choose a supplier.
4.Original Used — Disassembled from the secondhand phone.
Second-hand screens are divided into large scratches and small scratches. Usually the price is determined by the severity of the scratch.
5.Original New — Full new screen from original manufacture.
Unstable supply also expensive.
For Samsung OLED display assembly
In addition to the J5 Prime and J330, the Samsung screen is basically based on OLED quality. The screen is very fragile. If it replaced by an unprofessional technician, the screen will be damaged when the frame is installed. This situation is not surprising. Therefore, recommended to purchase the screen with frame, which greatly reduces the RMA and save times.
1.Aftermarket TFT — Production by aftermarket manufacture. (Backlight unit with/without Adjust)
The thickness of TFT quality will be thicker than OLED. TFT screen belongs to LCD. Final Good Yield: 93%. Many customers install the screen and crush the corners of the display cause damage.
2.Aftermarket OLED — Production by aftermarket OLED manufacture. Display panel production by HH(Hehui) & GH(Guoxian). Just like the iPhone Tianma, Youda and Shenchao quality.
This kind of quality is commonly known as OLED, but it is not an original display. Third-party factory will buy OLED panel from HH & GH. And cut the OLED panel to different sizes for different models. Then pressed front glass by laminating machine to OLED panel. Very suitable for wholesalers and repairers, the quality also stable.
3.Original Refurbish — Only change front protective panel with frame，or only replace front protective panel.
The price of most wholesalers and retail repair shops is acceptable to refurbished high quality screens. And it is much more stable than the Aftermarket TFT quality.
The quality price of the without adjustable function price will be much lower. (with/without adjust means the Backlight Adjustment function)
4.Original New — Full new screen from original manufacture.
Samsung has sold a new service package, but the price is still more expensive than the China supplier (AMO), the supply is stable, but the testing process is especially important.
For Huawei lcd display assembly
Huawei screen quality is mainly based on two types. The new models will be developed to OLED quality, such as Mate 10 pro, P20 pro, P9 plus, Honor Note 10. The most hot sell quality is Semi Original quality. The price is cheap, the reason for the return is basically because of the touch function.
1.Original New — Full new screen from original manufacture.
The full new quality is often sold in batches, be monopolized to sell at a high price. It is sold to all part of China as soon as it appears. After all, Huawei mobile phone sales are the best in China.
2.Semi Original — Only replace front glass, but display glass with backlight are full new.
This is the difference between Chinese brands and other brands. The touch screen and display screen of SEMI quality LCD screens are original experience. The reason is that both the display screen and the touch screen are original quality. Only the old models will be replaced with the copy touch screen. SEMI quality are more stable than original quality. Therefore, the return goods is greatly reduced. This is the best choice for every wholesaler and repairer.
