1 MD QUALITY GUIDE PRIME, SELECT, AND BASIC iphone SCREEN ASSEMBLIES 1

2 What Does Quality Really Mean? IN AN INDUSTRY WITH A CONSTANT INFLU IN RELIABILITY, DEFECT RATE, AND CONSISTENCY, IT S IMPORTANT TO ASK: WHAT DOES QUALITY REALLY MEAN? AS AN OVERUSED WORD IN THE INDUSTRY, MOBILE DEFENDERS HAS SET OUT TO QUANTIFY THE TERM. As a first step, we did extensive research on OEM and aftermarket screens, to pinpoint visual preferences of the end-user. We measured brightness, black brightness, whitepoint color temperature, polarizer transmission, and other factors to rank and differentiate the parts produced by our suppliers. The most consistent performers were separated to create the tiered grading system that we have today. From there, we implemented strict manufacturer screening methods and testing specifications for the screens we sell. With our MD China office, located in the heart of the Shenzhen marketplace, we oversee the entire process to ensure our products are staying within set specifications even as the parts market continues to evolve. Why set our own specifications instead of using common LCD brands such as Tianma? We tested popular LCD brands side-by-side and across models, and found that each screen looked and performed differently within each group. Dedicated to sourcing quality parts consistently, we started working with a factory that produces screens to specific standards for each of our MD lines. Each component in a display has an effect on the performance of the part, leading us to ignore specific LCD brands that don t meet our quality standards. 1

3 Deeper Look at our Screen Lines Our iphone screen grades consist of three tiers: PrimeParts, MDSelect, and MDBasic. Each of these grades is subject to the same level of reliability and functional testing. The differences between these grades is the exact components used and the visible performance of those components. MDBasic is our value aftermarket grade, created to offer high quality at a lower price point. These parts are selected from the same tier as many stateside suppliers, but exceed industry standards in performance and build quality through testing and validation. MDSelect is our premium aftermarket grade of screens designed to offer the optimal equilibrium between quality and cost. The quality goal of MDSelect is to provide the best performance, fit, and finish possible from an aftermarket part. PrimePart screens consist of OEM LCDs, with refurbished components from original assemblies. It is important to note that there is a common misconception in the industry that OEM parts are 100 percent original, or unused, while in actuality, 100 percent original parts are cost-prohibitive for the average end-user. For this reason, quality aftermarket components undergo continuous evaluation to ensure they maintain the quality we promise. 2

5 Component Grade Differences LCD OEM: Original LCD sourced from a factory second-assembly or recycled. High Grade Aftermarket: Designed to perform favorably when compared to an OEM part, with comparable brightness, contrast, response time, and polarizer performance. Value Aftermarket: Selected with cost and basic function as primary concerns. This part has lower performance standards, and is not guaranteed to pass the polarization test. Polarization Polarized sunglasses are used to neutralize the glare from water and reflected light. A film polarizer layer in the sunglasses blocks a majority of light that is not in line with the axis of the polarizer. This removes a lot of incident light which can improve contrast. However, most LCD s rely on a polarizer in front of the LCD to pass only the intended image from the display. Sunglasses will block visibility of most aftermarket LCD s at some angle. To avoid this, a special polarizer layer is used on certain LCD s. OEM LCD s contain a special polarizer layer. Though difficult to source in aftermarket assembies, we saw the importance of the polarizer layer, and searched for suppliers that use this high grade part. The polarizer layer is required on our PrimeParts and MDSelect screen assemblies, while MDBasic offers a more economical screen without this layer. Glass Oleophobic coating: A surface treatment which resists smudging and has a low surface energy. This makes the surface easier to clean and maintain. Bonding Cold Press: High grade frame-toglass bond process using CNC-applied solvent-based adhesive that better withstands stress such as flexing. All iphone 6 and newer parts use cold press bonding. Hot Press: A low cost, fast bonding process that uses a heat-sensitive adhesive. The iphone 5 series and older parts use this bonding method. Frame Assembly Contents ALL three grades of frame assemblies include the front camera and proximity sensor brackets, ear speaker grill and gasket, and connector pads. Within the MDSelect line we offer an assembly with: back plate home button extension flex (where applicable), front camera and sensor flex, ear speaker, and speaker/camera mounting plate, with screws pre-installed. 4
