What is OEM and ODM and OBM

ODM, namely Original design manufacture,which means that a vendor entrusted with design capability and technological level design and manufacture products based on another vendor’s specifications and requirements and authorization contract.

OBM, namely Original Brand Manufacturer,which refers to those specifically accept other enterprises’ OEM production requirements instead of creating their own brand.

OEM production, namely Original Equipment Manufacturer, also commonly known as Original Entrusted Manufacture,which means that the brand producers do not directly produce products, but by using their key technology grasped is responsible for the design and development of new products and control the sales channels, specific processing tasks would be done by the manufacturers entrusted by contracts,then buy the low-priced products and directly paste their own brand names on the product. This cooperation commissioned production refer to OEM ,the manufacturer undertaking the processing tasks is called OEM manufacturers, their products are called OEM products.

What the main differences between OEM and ODM is that the former get product design made by the commission- whether the overall design or by whomever – and the trustee shall not provide third party with the design of the product; the latter is the producers who design and manufacture , and the finished product is bought by others. Whether the producers can produce the product depends on whether the third-party buyout this design. OEM products are tailor-made for the brand vendor(not the manufacturer), requiring that the manufacturer could past the vendor brand name for the manufacturer’s business, but the producers shall not crown their names on the further production. ODM is based on whether the brand companies is able to buyout copyright of the product. If not, the manufacturer is entitled to their own production, as long as there is no recognition to the company’s corporate design. To put it plainly, the key difference between the OEM and ODM is who is eligible intellectual property of the product to be manufactured, and if the commissioning party own the intellectual property rights to the product, that is OEM; and if producers or manufacturer carry out overall design, that is ODM.

What is Virtual Reality glasses device

Virtual reality glasses device, referred to VR glasses, is a brand new human-computer interaction mean by means of a computer and the latest sensor technology, simply means that electronic devices step into the virtual world.


So what is VR device? First of all, we need to understand virtual reality device ≠ headset display device . In general, VR device can be divided into three categories: external headset device, Integrated headsets device, glasses box. External headset device do a good job in the separate screen and complex product structure. Integrated headset device products include Samsung Gear VR and other 3D VR Box glass headset. Simple, inexpensive glasses box is Google DIY Cardboard


Then, let’s figure out what the principles of this type of VR glasses is, our eyes can see things independently,that’s why human beings is able to see three-dimensional scene. Because left eye spaces from right eye, resulting in some subtle differences in the perspective of two eyes, and this difference makes a bit displacement of the individual scene two eyes get. The difference between the images left and right eye get is called parallax image, human brain skilfully fuse what get from both eyes, resulting in a sense of space stereoscopic effect in the brain.


You just require a mobile phone and upload 3D video and movies and games in the phone, you can enjoy the pretty good 3D pictures presenting at 360 degree  viewing angle on the phone screen via the device, relatively low cost, easily accessible to the average user


3D VR Box headsets is based on equipment gyroscope to detect the user’s head wobble data,the virtual reality devices demonstrate the data in front of the user by calculating the graphical. Then use the gyroscopes to detect the user’s head wobble data, and match the pre-prepared scenario to to achieve integration with the virtual scene. You could enjoy the 3D pictures from the phone screen via a magnifying lens.

How to pick up a competitive hair straightener and quality hair straightener factory

Hair straightener is pouring recently; there are sorts of hair straightener including flat iron and hair straightener brush flooding at retailer store , Amazon ,Ebay ect ;but how to choose a competitive hair straightener and quality hair straightener factory  is very confusing;take it easy!ONU MALL would like to tell you what we know;here we go!


First of all,you need to make sure where the hair straightener brush iron originates from,take China where most of straightener are made for example,majority of quality straightener made in Shenzhen China is superior to most of those originated from Zhejiang province China despite those made in Zhenjiang is generally 1.5-2 USD cheaper than those made in Shenzhen factory;the PCBA of knock offs made in Zhejiang is generally 1cm narrower than those with sound quality in Shenzhen;The PCBA is the most important part in hair straightener iron; It dominates how long a hair straightener heat up and how the stability is.


Then.Some brush is cheap, some iron brushes is higher in price, you are always getting what you pay, just buy the one certified by CE,ROHS ; some brand is known as quality while the price is disappointed;definitely,just switch to those slightly cheaper double checked by QC team in the factory ,do not be tempted by those with attractive packaging without CE ROHS certification and QC testing.


Furthermore,you must heat it 2-3 minute before use;make sure straighten a pinch of hair and carding slowly in practical applications;


Above all,for a wholesaler ordering big quantity, try to ask the factory marking your customizable LOGO on brush making your product unique; given how to choose a quality supplier,the most important factor is to ensure your supplier have doing leakage of electricity test;which is a fatal factor and related to whether the brush could safely used; moreover, you need to check out whether your supplier have past by CE,ROHS ;Thirdly, make sure your supplier factory have QC team; the hair straightener from ONU MALL factory has strictly been tested for 30 minutes/PC by our QC team ;which will undoubtedly assure that the straightener brush could be heated timely and LCD work in good condition;So if you make a order ,what must be emphasized is that all of the brush shall be tested before delivery.You must ensure that all of the straightener brush through the appropriate safety tests even if sometimes the delivery would be missed because of the test.

How to solve dizziness problem after wearing glasses 3d Box virual reality headset

Since 3D box glasses headset can be worn comfortably to allow us to freely enjoy the ultra-stereoscopic 3D gaming and video, it has swept the world, it is expected to become the latest hottest virual reality products during 2016. However, many people get dizzy when wearing such 3D box virual reality headset glasses, why?


Given the user experience, the sense of dizziness can be attributed to visual difference .
As far as the display device is concerned,what causes vertigo are generally be divided into two aspects of hardware and software, hardware part is unreasonable structure design, such as the distance between the glass and the pupil is not improperly, resulting in inconsistent images obtained by left and right eye;Large lens aberrations and distortion leads to severe picture distortion;picture updating made by incorrect image refresh frame rate does not reach the requirements on the human eye.The three-dimensional model is unreasonable, the parallax adjustment exceeds the tolerance range of the human eye, the stereoscopic image exists horizontal or vertical deviation which is not easy to form three-dimensional effects.So, what are any good solutions to these problems it?here we go!


In terms of hardware or software or a combination of both, primarily solve all these five issues:
1, improve the frame rate refresh

2, increase the resolution

3,reduce picture distortion

4, optimize head motion tracking

5, optimize content


Specifically, the hardware of these aspects which need to be improved are: GPU, sensors, displays, chip, an imaging lens, and the interpupillary distance(IPD)and the distance adjustment structure. Software, the image algorithm needs to be improved
Oculus uses aspherical to reduce image distortion, the resolution of the first generation of products is 720p, the second-generation upgrade to 1080p, they also adopted a series of actions for the decline in delays, the entire process the new image from the user inputting to completing has been compressed to control in less than 30 frames per second. At the same time, the company also use some software algorithm to correct the distortion. Currently, Oculus research focus has shifted from cuts in delays to tracking accuracy, image quality, resolution.

HTC vive reduce the delays in the image by improving the image refresh rate, refresh rate is 90 frames per second (but still not as good as Oculus) while achieving a more accurate head movement tracking through more sophisticated sensors designed .

Nvidia as a chip maker and Epic Games which is the developer on iOS action game named “Infinity Blade” series co-developed a “GameWorks VR” technology. GameWorks VR technology make the players see the game screen with a higher resolution central region through the Multi-Resolution Shading( abbreviated as MRS) “way, the area around the low-resolution form is displayed. This technique makes the game screen refresh rate greatly improved, lifting about 50%

The elimination of a sense of dizziness is not just the responsibility of virual reality vendor,the game developers also played a big role. On the one hand, the game developers cut the delays by improving the game frame rate abatement, as most of the modern game is about 60fps, with this level of conversion, when each figure transferred to GPU is 16.67 ms. If this rate can be increased by 1 time by game developers, then delay produced by this part would be halved. On the other hand, considering optimize game content, take the roller coaster for example, no matter how realistic it is, it would make you vertigo. This requires developers to make reasonable arrangements on the content.
