The thickness of a single LCD glass substrate is very thin, and even holding it in your hand makes people feel like holding a thin cardboard, for fear that this glass substrate will be broken by accident.

However, when the three layers of glass substrates are glued together, the thickness that could have been ignored has now become a little thicker, and the same thickness of the three layers, plus the thin and negligible layer of glue in the middle, has changed from a negligible thickness to a somewhat thick feeling.

This is the same as the accuracy of the parts on the machine tool, and the accuracy of a single part may only be a little different, but the accumulation is more, and the accuracy of the entire machine tool will decrease.

"Li Dong, the thickness is still a little thick, I'm afraid that the display will have an impact on the color of the pixels."

Looking at the thin glass plate that looked like a book in his hand, He Qiang frowned, this guy who made him feel a little heavier was still a little thicker, and there was at least a millimeter distance between the top layer and the bottom layer, so that there was a distance of more than a millimeter between the display pixels of the first layer and the display pixels of the third layer, wouldn't it affect the imaging quality.

Although this is the first color LCD display, it must not be much worse than a regular CRT TV.

"It's okay, we'll see how it looks later."

Li Jian remembered the kind of LED display that was often used to make billboards in later generations, if you look closely, the pixels are rough and scary, but when you look at it from a distance, when you play a ball game or any advertisement, it is not so delicate.

He Qiang's consideration is not unreasonable. It just depends on how far away this reality is.

The two men connected the other end of the LCD panel with a special wire connector, and then put it into a plastic shell that had already been manufactured. I adjusted the distance with the card slot next to it, placed the LCD panel perfectly in the card slot, and then connected those wires to the controller on the other side.

These are all designed by Li Jian in advance, on a screen with a size of 32 and 10 inches, the real size of the display is only 7 inches, and within the area of these 7 inches, there are only 2,000 pixels that can really be used for display. After all, this is a primary LCD screen, not a high-definition mobile phone display like the later generations.

Handmade LCD panel, 2,000 pixels. It's a lot.

These wires are less than 2,000 wires, and at the current level that Li Jian can do, he wants to make 2,000 control wires. It's better to let him just draw a 2,000-piece control circuit.

The white backlight next to the display is activated. The soft light shines on the LCD panel, and it seems that the whole panel is like a lake at night, with a layer of faint ripples.

"Let's go."

Li Jian said a word and pressed the button next to it, which is the switch of the controller, which has a control chip in it, which can control each pixel display unit on the display, and press it. On the LCD screen, a patch of blue first appeared, followed by green. And then there's the red.

Three colors flashed, and the screen instantly turned black and then white again.

This is the controller is testing the display effect of the liquid crystal, whether it can achieve the required display of various colors.

He Qiang looked at the small piece of screen, frowned, this is a piece of LCD he made by hand, and he didn't test it after making it alone, now it's displayed, each piece is a success, and the overlap of pixels is also very good, the only fly in the ointment is that there are a lot of bad pixels.

If the entire seven-inch screen has 2,000 pixels, the naked eye roughly scans it, and there must be at least about 100 dead pixels.

The dead pixel rate of handmade products is much higher than that of mechanical equipment.

It can only be said that when I operate by myself, the hand is not stable enough and the movement is not gentle enough, so the bad pixel rate is extremely high.

"Hmm!"

Before his eyebrows could be stretched, He Qiang saw that the font began to be displayed on the screen, which was of course also the data stored by the control chip in advance, and there were rows of small characters on it, saying that they were small, and they were also the size of peanuts, because of the existence of bad pixels, these fonts that should have been purple were like crops that had been bitten by locusts, and there were loopholes everywhere.

"There are too many dead pixels, but judging from the display of pixels, it should be okay, at least at a distance of about one meter like me, I can't see the error before and after the pixel display."

Li Jian has already taken a step back, two steps away from the display screen, and at his distance, the roughness of the pixels is basically negligible.

It's just that there are too many bad points, so that the small characters that are already difficult to read are even more ambiguous, and they can only be seen after careful identification.

Because there are too many strokes in hoe He's hoe, in the originally dense space, there is only one left to dry for a month and a hand, and it is impossible to see that it is a hoe with a hoe.

"Well, when I was operating manually, I couldn't grasp the strength well, and recently it has been a mechanical operation, and the manual operation is rusty, so there are so many bad points."

He Qiang was a little embarrassed, a little sad that he didn't perform well in Li Jian, and after saying that, he gritted his teeth and secretly made up his mind that he must practice manual operation well when he turns around, and he must control the bad pixel rate of manual work at less than five percent.

Li Jian looked at the two corners of He Qiang's mouth bulging through the mask, knowing that he was secretly making up his mind, and gently patted He Qiang's shoulder,

"Don't worry, it's not your business, we're just experimenting now, the real application must be fully automatic mechanized operation of the production line, manpower is on top of this subtle operation, after all, it is not as accurate as the machine, especially since we haven't practiced much."

Seeing that He Qiang's face softened slightly, Li Jiancai continued,

"Test the effect first, if you can, when the production line stops in a few days, I will let people make a little liquid crystal material, use the production line for processing, if we can build a color LCD production line ourselves, and then we will automatically manufacture color LCD monitors and color LCD TVs."

Thinking of this, a smile appeared on the corner of Li Jian's mouth, although he was blocked behind the mask, He Qiang could also see Li Jian's happy mood, and couldn't help but think, even if Li Dong made PHS in the past, when he was driving those things, he was not so happy, how can he say that color TVs are so happy, is the market share of color TVs so much more than that of optical drive box PHS?

Or is it the LCD market, which is to be occupied by Qianghua, which can improve our Qianghua's market position and company image, and it is also a well-known technology company abroad?

Li Jian naturally didn't think so, but he remembered the red plasma technology he gave to Nisso, the development of plasma color display technology, if there is no own fueling, it should be more than ten years before it can mature, and now he gave the last red display technology discovered at that time to Nisso, presumably it can improve the development speed of Nisso, and now he may have researched one of the other two colors?

If you launch a color LCD monitor, color LCD TV, that ultra-thin feeling, will definitely surprise the market, and then burst out of huge purchasing power, all this is seen by the Nisso company, they will vomit blood angrily, their hard-earned technology, the exchange of technology, has not been used, has reached the end of the road.

Even if plasma technology is studied, it may really be more advanced than liquid crystal technology, in the case of losing market opportunities, and the gap is not large, how can it compete with liquid crystal color imaging technology, unless the technical gap is large enough to be detected by the naked eye, it is obvious that the gap between the two technologies in the primary stage of development is really not that big.

But if it's just like this, it's too petty, and this can pit Niso a lot, it's better to be an adult, and then promote the development of Niso plasma technology.

In this way, the front foot sells the patented technology to the Niso company, which completes their color plasma imaging technology, and the back foot of its own company launches the mature liquid crystal display technology, and also promotes it to the Japanese market.

In this case, the production of liquid crystal monitors and LCD TVs by Qianghua Company must be kept secret, at least until the plasma display technology is sold.

This is the reason why Li Jian secretly laughed, he saw He Qiang looking at him, wanting to ask but not daring to ask, and quickly straightened his face,

"Look, all kinds of colors are displayed, the same color is not a chroma, but constantly changing from dark to light from light to dark, basically there are no too obvious defects, but in order to ensure quality, we still wait for the machinery to be manufactured and glued before re-doing the system test."

Li Jian thought for a while, and then continued,

"It's too troublesome to control with wires, so next time I will directly control with the control chip and integrate the control chip into the substrate......"

Where is He Qiang listening and nodding, such a naked eye test is actually just to test whether such an idea is possible, the real specific data test, it is necessary to create a substrate without so many dead pixels, and then test it in a professional testing laboratory, so that the data such as color temperature and color difference can be tested clearly.

And what Li Dong said is even more reasonable, on this display screen, there are more than 2,000 pixels, but the wire can't be made into 2,000, in that case, the optical connector may be as thick as an arm, and the connection with the liquid crystal display substrate is a problem, not to mention the test, it is the best way to control it directly on the silicon board with an integrated circuit.
