The biggest challenge here is the graphics processor and graphics decoder, both of which use chips.
Since we don't have the chips yet, we can only make two or three wafers using a lithography machine for research purposes.
Fortunately, we had the graphics card chip architecture diagram. The two architects we hired worked for three days and three nights revising the graphics card diagram and reorganizing it. They also had to modify the red and yellow areas.
Only a few graphics processing unit chips were produced, and they were worth over ten thousand yuan.
This is the cost of the experiment. If it goes into mass production, the cost will be spread out evenly. It might be worth tens of dollars.
With a graphics processor and a decoding processor, a computer with a graphics card can demonstrate the value of the graphics card in processing images and videos.
Although the color processing is only around 480P, this is already close to the pixel value of the fluorescent screen.
Furthermore, LCD panels can be cut into larger sizes according to their dimensions.
To conduct experiments and observe the effects, Xing Baohua from Changhong transported the largest panels available during panel cutting: 32-inch, 40-inch, 42-inch, and 50-inch panels.
Any bigger and the effect wouldn't be good, so we didn't let them use it. A 50-inch screen is probably the limit for watching 480P. Any larger screen and the graphics look like a mosaic of pixels.
The larger the size, the more squares you see.
Unless we increase the pixel count further, which is theoretically possible but practically extremely difficult, and the hardware simply can't keep up! We can only move forward step by step.
Now that we have independently developed a graphics processor, we still don't have enough lithography machines. All kinds of chips are relying on this thing.
Set aside the computer monitor for now and test TVs larger than 32 inches.
The most crucial technology here is the analog-to-digital signal conversion. Xing Baohua had been tinkering with this stuff back when he was playing with analog mobile phones.
Although the modes and internal structures are different, the principle is the same; the only difference is that one transmits voice signals while the other transmits video signals.
By combining a graphics processor and a decoding chip with a high-power receiver, you can receive TV channels.
All the functions that old TVs had have been transferred to LCD TVs. They look thin, but they're actually quite heavy.
First, receive wireless signals, then test the wired frequency band.
After the basic data met the standards, Xing Baohua gave the R&D staff a bonus and held a small celebration party.
Besides the LCD panel, the internal hardware integrated circuits and even the decoder are all the results of Dami's independent research and development.
Since the Japanese or other LCD screen manufacturers have not announced their latest achievements, the Japanese can now proudly declare to the world that they are the first manufacturer to develop a Japanese LCD TV and display screen, and that all their technologies are ahead of their competitors.
As for whether it is ahead of its global counterparts, Xing Baohua doesn't know. Since no one reports it or says anything, then he is the world's number one producer.
If you're going to brag, you have to make it sound like you're number one in the world, otherwise how can you really pat yourself on the back?
Although it has been developed, we are not in a hurry to announce it; we will apply for all the patents that can be applied for first.
The monitor factory has not yet started production, and Changhong's technicians have just finished assembling a few production lines.
The camera is progressing well, and the main video phone has already been produced. The main material is a 4-inch fluorescent screen produced by Luzhong, while the radio frequency head and picture tube are imported from Shanghai.
At the time, a dozen or so units were produced for testing purposes. Unexpectedly, the test results were good, so production continued. In Xing Baohua's words, they decided to produce two thousand units first and then see how it went in the market.
If this thing is produced in large quantities, it will become a useless product. We can't exactly mass-produce a batch of 3-in-1 machines like Sony and Panasonic!
Not only can you watch TV, but you can also listen to cassette tapes and play the radio?
This item is rarely seen on the market. Firstly, it's expensive; secondly, it's impractical; and thirdly, sales volume is small, so production ceased after a single batch. Most of the items you see are in the hands of collectors.
Therefore, when producing small-screen TVs, Xing Baohua first produced a batch and put it on the market to see how it went.
After all, video calls are only suitable for doorbells, which limits the sales target.
However, the camera itself was fine, but after the VCD was written to twice, some data was lost due to the scratches on the disc.
One reason for this is the quality of the disc, and another is that the uneven surface of the disc causes friction with other objects when it is running at high speed.
This is a technical issue, or perhaps the disc manufacturer produced a batch of discs with slight deviations in the data for the central hole.
Discs are inexpensive, mainly because they are made of a very thin aluminum or gold diaphragm on a plastic layer.
Then, the laser head in the optical drive is used to burn and read the data.
This type of disk, like the disks in floppy disks and hard disks, uses binary, with data composed of 0s and 1s.
The only difference is that the film on the optical disc is very thin. Once it's smoothed out, there are only one or two more chances to burn it. Any more and the disc is ruined, unless the special material on the disc is coated thicker.
Even if it's thick, the effect isn't very good. In short, it has many problems, and a disc can only be used once or twice.
It is far inferior to a magnetic hard drive.
Cheap hard drives can't achieve such high storage capacity, and they're expensive. Optical discs are cheaper economically, but honestly, using them is a recipe for disaster.
It's better to spend more money and continue using the cartridges; the longer you use them, the more the cost of the cartridges will become apparent.
To avoid ripping people off, Xing Baohua hired IBM engineers to help solve some of the storage problems.
Glass, glass base.
This is a concept proposed by a technician in their hard drive lab.
Because glass is not easily scratched, it can be coated with aluminum metal material, allowing for multiple writing or erasing processes.
