How to choose a good mobile screen supplier

This article is just for those wholesalers and retailers who is doing business in aftermarket phone screens, if you are a customer who want to buy such products for your broken phones, this is too complex for you, just leave these to your repairman.

Writers background:

10 years experience of manufacturing the smartphone screens, factory owner, 2 years experience of Apple supplier, knowledge of Apple standard, 4 year experience of motor engine parts, knowledge of management, quality improvement and cost reduction.

When we talk about the aftermarket screens, we are talking about the factory products which are produced mainly in China, and these factories are mainly located in Guangdong province, it is the center of electronic production world. When someone breaks his or her phone screen, they need a replacement, if they go with official store, it will cost them quite a lot of money. Almost everyone breaks his phone screens, that is why the aftermarket screen industry is built, with lower expense and faster replacement.

If you are a wholesaler or retailer for phone screens, it is your duty to know more details about your products, the more you know, the less risks you will get, customer service, time costs and operating cost depend on these, you never don’t want to argue with your supplier or customers for these things you don’t know.

“ The market is huge, but the business circle is small…” a friend of the writer said, he also owns a factory to produce phone screens, “there are less than 50 factories in China which are producing the aftermarket phone screens, and we know each other very well, we are friends and competitors, other manufacturer can not be called as a factory, they are more like private workshops.”

To produce smartphone screens is like to cook, you need fresh and qualified material, highly standard and process must be followed, skilled employees are required, followed with strict inspections and safely transportation.

Before we talk about the elements above, let’s get to know what is a phone screen and how they work. In the market, there are mainly 3 types of screens: original,OLED and LCD.

ORIGINAL:

Mobile company like Apple, Samsung and Huawei, they don’t sell OEM parts, they have very strict policy for that, and these factories which supply OEM parts to these whales, they definitely don’t want to loose their business with breaking their policy.

So when we talk about original screens, we are talking about refurbished ones, they are removed from original second-hand phones and those phones which breaks the glass, after processing like replace the glass, re-new the appearance by skilled repairman, they become original screens. This kind of screens with most of the parts the same as OEM are the best quality screens in the market, they always come with high price.“ To give them choices”, this is always a good idea for customers, “and to make them affordable, to make each cent they spent countable” 

The difference between LCD and OLED screens

The full name of the LED is a light-emitting diode. Like the traditional semiconductor industry, an LED display is a display method that controls a semiconductor light-emitting diode. It is usually composed of a plurality of red light-emitting diodes, and the display is dominated by the light of the light to realize text, graphics, images, and animation.

The OLED emits light by driving the organic film itself. OLED is a congenital surface light source technology, and the light emitted can be red, green, blue, white and other monochromatic colors, thereby achieving the effect of full colour, belonging to a new principle of illumination. That’s why it praised because it has the characteristics of “self-illumination”.

OLED screen get wider viewing angle and thinner thickness

As the source of light in LED is not individual for each pixel that’s why displaying a black colour, it mainly relies on the deflection of the liquid crystal molecules to shield the backlight. Therefore, when the liquid panel displays a black screen, there will be some light leakage, and the ultimate black field cannot be obtained.

OLED technology can turn off independent pixels and zero their brightness. In theory, the contrast of OLED technology can be infinite. In the actual display effect, the video content based on the dark scene is the biggest challenge of LED, and OLED can easily deal with it.

Raw Materials

Factories which produce smartphone screen buy raw materials from different suppliers, these suppliers focus on backlight or OCA (Optically Clear Adhesive)or other parts of the screens, their products quality differs from one to another. Incoming material inspection is the first process which we highly treat with, not only from the appearance, they look almost the same between different suppliers’ material, but also the functional inspection. Unfortunately most of the screen factory don’t have this kind of inspection machines. Sometimes they ask the raw material supplier to provide their qualifications, but in this field, qualification paper means nothing. This is aftermarket screen business, there is not enough standardization for it. Smartphone screen used be high-tech products, we are talking about pixels and micrometers, it means you can not inspect them just with your eyes. Luckily, we realized this issue from the start of our factory foundation, it is not a problem to us now.

Standard of production (SOP)

As a member of this field, we create our own SOP from the beginning, SOP makes the stable quality and saves our cost, which means we provide high quality aftermarket screens with lower price. SOPs are taught to our employees, we obey it through all the process. As a wholesaler, you may ask your supplier if they have such paperwork in their plant, i doubt if they know what it is.

Inspection before delivering and respond

After strict process monitored by SOP, the final inspection is required, this is the step most of factories will follow, but the quality can never be better by inspecting, quality check piece by piece is needed, many wholesalers meet the problem of after-sale, function failure, flex slip, bad pixel, back-light leak… some of them can be inspected during final inspection, some of them can not, the quality can be only controlled during the production.

Fast respond means customer service, and time saving, because of the time difference, wholesalers from all around the world can not be served in time, not all the factories have 7*24 service.

Continual cost reduction

This is the element most of the aftermarket screen factories won’t follow, but we value it, continual cost reduction means we provide the same quality as today with a lower price tomorrow, to reduce the cost is not to cut corners, it is to raise our productivity and improve our process of production.

So, if you are a wholesaler there, ask these questions to your supplier for your customers, it is your responsibility to do that, and it will save you a lot of troubles. There are still a lot of things need to be done for aftermarket screens, the market is so crowed like a real bazaar, only those one with responsibilities can survive.
