Cool open U55 evaluation 5.0 version of the operating system interface introduced

How about CoolTV U55? Recently, CoolTV U55 has upgraded its operating system and introduced trials for the new version of the CoolTV U55 interface. Cool open U55 TV 5.0 has a qualitative leap compared to 4.0, the first is the home page more concise, clear, clear, want to show things out, it is easy to find; put the user may use more things on the easier to find The location, compared to 4.0, the box to find their own installed software, or open the local file, must be a lot easier, the user experience has greatly improved.
1, home page





Press the left button to call out the setup menu


2, film and television center



Variety


TV series


the film


VIP area


Feeling that the film and television center is not bad, a lot of new resources (TV dramas don't know if they are new, they haven't watched TV shows for a long time, and several movies have recently been released)

3, history collection

History corresponds to the most recently used application


Do not know how to collect, so my collection is empty (Is it film and television, well, I admit, I went in once or twice, did not see the movies and TV dramas inside)



4, my game

There is no gaming device, so I have not used TV to play games. It is empty.

5, my application

This is my own installed software (including some of the applications)



App recommendation page



game



software



Software management



6. Game Center



Recommended game page





Specialized in gamepad games, somatosensory games, remote-controlled games, equipped students can get up, there are still many classic games.



7. Education Center (If you have children at home, you can use this one)



8, Cool open Mall





Want to enter and see, the results began to circle, install the software


After installing a lion head, and reminded the installation is successful, Suning will be installed.

Anyway, already installed (do not like this push method, at least remind you whether to install), click on it and see it


Stuck in this picture for a long time and finally got to the homepage


It's useless, it doesn't work, I don't know if it's incompatibility or what's wrong, it's not good to make it, really use it to do shopping, it's crazy.

9. Brand Center

Curious, point in and look down


It does not seem to be used as Internet TV, standard content.

10, tourism center





Tickets and hotel services are provided.

11, application circle

Same as my application

12. Local media

For viewing content on a USB device


This is still very good, see a piece of cool, the screen is big enough


13, signal source

And the "Set-Top Box" function on the remote control, one more choice


14, setting



Network, Bluetooth settings




Image settings





Listen to the model alone, use it best when listening to songs, and save energy.



Universal settings





About this machine



Configuration information



15. TV school

This software is ok, live broadcast, on-demand broadcast, all-in-one can be pushed from the mobile phone to the TV, and the mobile phone does not need to play synchronously. Just push the address.



16, as a computer display

Since I bought the U55, my monitor has returned to the box. The TV is used as a display. The computer uses a wireless mouse and keyboard. Don't be too cool to operate. Especially when playing games, the screen is loud, loud and stimulating!



In short, the increase from 4.0 to 5.0 is too large, too much information, too much to use to better understand.

Unconsciously edited for almost two hours, the share has been shared, the following talk about new

system

Problems encountered:

1. The history in the history collection will not be updated automatically. Now the content inside is still in accordance with the content before 5.0. Later, the operation of opening the software is not recorded, and the operation history cannot be synchronized.

2. The ordering of software in my application is not fixed. The order of yesterday's opening and today's opening is not the same. I hope it can be optimized. Also, it is better to photograph the software installed by the user to the front, or to add the order from Defining features, after all, is what they really want.

Rigid PCB , the largest number of PCB manufactured


What is Rigid PCB - Rigid PCB Definition


Rigid PCB is a kind of Printed Circuit Board, and is the largest number of PCB manufactured. It is made of solid substrate material, which can effectively prevent the distortion of the circuit board. Perhaps the most common Rigid Circuit Board is the computer motherboard. The motherboard is a multi-layer PCB designed to distribute power from the power supply while allowing communication between all components of the computer, such as CPU, GPU and RAM.

Rigid PCB can be used in any position where the PCB itself needs to be set to a shape and maintained during the remaining life of the equipment. Rigid PCBs can be anything from simple single-layer PCBs to eight or ten-layer multi-layer PCBs.

Rigid PCB and Flexible PCB are totally different. One is flexible and the other is rigid. Therefore, their application scenarios are different. In addition, there are rigid- Flex PCB . There are similarities between them. However, all rigid PCB have single-layer, double-layer or multi-layer structure, so they have common application scope. This is the case.

WHAT IS RIGID PCB



Some characteristics of rigid PCB


  • Rigid PCB is a kind of conventional PCB, which can not be like flexible PCB, because rigid PCB can not be twisted or folded into any shape, because it has FR4 reinforcement, which is very useful for increasing stiffness.

  • Rigid PCB is made up of copper trances and paths which are incorporated on a single board in order to connect the different components on the board. The base material of the board is made of rigid substrate which gives rigidity and strength to the board.

  • The computer motherboard is the best example of a rigid PCB with a rigid substrate material.


  • Once rigid PCBs are manufactured, they cannot be modified or folded into any other shape.


  • Rigid PCB is cheaper than flexible PCB. They are traditional PCBs and are widely used in many electronic products.


  • Flexible PCB and rigid PCB have their own limitations and advantages in terms of ease of use and availability. Both of them are used to connect multiple electronic components on circuit boards.



Rigid PCB Manufacturing


Rigid PCB is made up of different layers that are joined together using adhesive and heat, providing a solid shape to board material. Following layers are used to develop a rigid PCB.

Substrate Layer - rigid PCB material


  • Substrate layer, also referred base material, is made of fiber glass.


  • The FR4 is mostly used as a substrate material which a most common fiber glass that provides rigidity and stiffness to the board.


  • Phenilcs and epoxies are also used as a base material but they are not as good as FR4, however, they are less expensive and feature unique bad smell.


  • Decomposition temperature of phenolics is too low that results in delamination of the layer if solder is placed for long duration of time.

Copper Layer


  • On the top of substrate layer, there resides a copper foil which is laminated on the board with the help of added amount heat and adhesive.


  • In common use, both sides of the board are laminated with copper, however, some cheap electronics come with only one layer of copper material on the board.


  • Different boards come with different thickness which is described in ounces per square foot.

Solder Mask Layer


  • Solder Mask Layer houses above the copper layer.


  • This layer is added on the board to add insulation on the copper layer in order to avoid any damage in case any conduction material is touched with the copper layer.

Silkscreen Layer


  • Silkscreen layer is located above solder mask layer.


  • It is used to add characters or symbol on the board that provide better understanding of the board.


  • White color is mostly used for silkscreen however, other colors are also available including grey, red black and yellow.

RIGID PCB VS FLEXIBLE PCB



The differences between Rigid PCB And Flexible PCB


  • Most of the electronics made use of traditional rigid PCB. However, technology has been evolved and many products abandoned rigid PCBs because of their inability to get folded or twisted. This has erupted the idea of flexible PCB and soon it became the prerequisite for most of the professionals in the market.

  • Manufacturing process of both rigid and flexible PCBs is same with some exceptions in terms of their flexibility, softness and cost.

  • Some extra measures are required for processing flex PCB when it comes to material handling. Also proper specifications are required in order to avoid any cracked solder joints when the board is bent.

  • Flexible PCBs are most costly than rigid PCBs, however, we are referring here individual cost of the flexible PCB, it may happen the overall cost of the project using rigid PCB is higher than the cost of the flexible PCB, but individual cost of flexible PCB will be higher.

  • Many cheap electronics make use of rigid PCBs including audio keyboards, desktop devices, solid state drives, toys and many electronic gadgets. However, flex circuits are observed in ultra high performance device because they don`t involve connectors also thinner than rigid boards and can be used in smart phones, cameras, tablets and GPS control system.

  • Both rigid and flexible boards can be incorporated together to construct a unified product that comes with both strength and flexibility.

  • Some flex PCBs follow the same design as rigid circuit design but they are not completely identical to the rigid circuit boards.

  • Flexible PCBs provide flexible and bending solutions and they also require less space and are mostly Single-Sided PCB.



When to Use Rigid and When to Use Flexible


  • Rigid PCBs typically cost less than flex circuits. I say "typically" because when considering the total cost of ownership there are some applications that, when using flexible PCBs, may be less expensive compared to using rigid PCBs. To get a true and accurate understanding of the total cost of ownership, you first need to appreciate the fact that flex circuits may eliminate the need for components such as connectors, wire harnesses, and other circuit boards. By removing these components from a design, material cost, labor and assembly cost, and scrap cost are all reduced.

  • Many electronic devices (laptop and desktop computers, audio keyboards, solid-state drives (SSDs), flat-screen TVs and monitors, children`s toys, and various electronic gadgets) employ rigid PCBs instead of flexible PCBs. However, flex circuits may be found in ultra-compact and/or high-performance devices, including GPS units, tablets, smart phones, cameras, and wearables.

  • Greater sophistication is not the only reason to use flex circuits; low-tech applications,such as LED lights, may utilize flex circuit technology, in some cases because it makes installation much easier.



Rigid PCB Applications


  • A computer motherboard is a perfect example of rigid PCB which is a Multilayer Rigid PCB, used to distribute electricity from power supply, and creates a conducting path between CPU, GPU and RAM.

  • Rigid PCBs are manufactured in volumes and once they are designed, they can not be altered or modified and remain same throughout the entire life span of the project on which they are placed.

  • Some low cost products make use rigid PCBs like toys, ,electronics gadgets, desktop devices and solid state devices.

  • You should also have a look at Double-Sided PCB, these are also Rigid PCBs.
