For the screen printing process, we apply ink through a mesh screen to create the desired image. The ink is then cured to bond it to the substrate. This is a low-cost printing method which allows a durable and vibrant print. Screen printing allows more flexibility in terms of ink colors and thicknesses and is usually used to print on products like cover glass, display glass and EMI shielding.AGDisplays offers frit or epoxy/polyester inks for printing.

The frit ink is configured of three parts, giving the ink a high adhesion to the LCD’s glass substrate. Once applied, the glass is placed into a tempering oven to fuse the ceramic ink to the substrate. Overall, the three-part combination creates a permanent and rigorous print.

The TFT LCD module is very suitable for industrialcontrol equipment, medical instruments, POS system, electronic consumer products, vehicles, and other products.

Important technical improvements of LCD, such as LED backlighting and wide viewing Angle, are directly related to LCD. And account for an LCD display 80% of the cost of the LCD panel, enough to show that the LCD panel is the core part of the entire display, the quality of the LCD panel, can be said to directly determine the quality of an LCD display.

The production of civil LCD displays is just an assembly process. The LCD panel, the main control circuit, shell, and other parts of the main assembly, basically will not have too complex technical problems.

Does this mean that LCDS are low-tech products? In fact, it is not. The production and manufacturing process of the LCD panels is very complicated, requiring at least 300 process processes. The whole process needs to be carried out in a dust-free environment and with precise technology.

The general structure of the LCD panel is not very complex, now the structure of the LCD panel is divided into two parts: the LCD panel and the backlight system.

Due to the LCD does not shine, so you need to use another light source to illuminate, the function of the backlight system is to this, but currently used CCFL lamp or LED backlight, don’t have the characteristics of the surface light source, so you need to guide plate, spreadsheet components, such as linear or point sources of light evenly across the surface, in order to make the entire LCD panel on the differences of luminous intensity is the same, but it is very difficult, to achieve the ideal state can be to try to reduce brightness non-uniformity, the backlight system has a lot to the test of design and workmanship.

In addition, there is a driving IC and printed circuit board beside the LCD panel, which is mainly used to control the rotation of LCD molecules in the LCD panel and the transmission of display signals. The LCD plate is thin and translucent without electricity. It is roughly shaped like a sandwich, with an LCD sandwiched between a layer of TFT glass and a layer of colored filters.

LCD with light refraction properties of solid crystals, with fluid flow characteristics at the same time, under the drive of the electrode, can be arranged in a way that, in accordance with the master want to control the strength of the light through, and then on the color filter, through the red, green, blue three colors of each pixel toning, eventually get the full-screen image.

According to the functional division, the LCD panel can be divided into the LCD panel and the backlight system. However, to produce an LCD panel, it needs to go through three complicated processes, namely, the manufacturing process of the front segment Array,the manufacturing process of the middle segment Cell, and the assembly of the rear segment module. Today we will be here, for you in detail to introduce the production of the LCD panel manufacturing process.

The manufacturing process of the LCD panel Array is mainly composed of four parts: film, yellow light, etch and peel film. If we just look at it in this way, many netizens do not understand the specific meaning of these four steps and why they do so.

First of all, the motion and arrangement of LCD molecules need electrons to drive them. Therefore, on the TFT glass, the carrier of LCD, there must be conductive parts to control the motion of LCD. In this case, we use ITO (Indium Tin Oxide) to do this.ITO is transparent and also acts as a thin-film conductive crystal so that it doesn’t block the backlight.

The different arrangement of LCD molecules and the rapid motion change can ensure that each pixel displays the corresponding color accurately and the image changes accurately and quickly, which requires the precision of LCD molecule control.ITO film needs special treatment, just like printing the circuit on the PCB board, drawing the conductive circuit on the whole LCD board.

This completes the previous Array process. It is not difficult to see from the whole process that ITO film is deposited, photoresist coated, exposed, developed, and etched on TFT glass, and finally, ITO electrode pattern designed in the early stage is formed on TFT glass to control the movement of LCD molecules on the glass. The general steps of the whole production process are not complicated, but the technical details and precautions are very complicated, so we will not introduce them here. Interested friends can consult relevant materials by themselves.

The glass that the LCD board uses makes a craft also very exquisite. (The manufacturing process flow of the LCD display screen)At present, the world’s largest LCD panel glass, mainly by the United States Corning, Japan Asahi glass manufacturers, located in the upstream of the production of LCD panel, these manufacturers have mastered the glass production technology patents. A few months ago, the earthquake caused a corning glass furnace shutdown incident, which has caused a certain impact on the LCD panel industry, you can see its position in the industry.

As mentioned earlier, the LCD panel is structured like a sandwich, with an LCD sandwiched between the lower TFT glass and the upper color filter. The terminal Cell process in LCD panel manufacturing involves the TFT glass being glued to the top and bottom of a colored filter, but this is not a simple bonding process that requires a lot of technical detail.

As you can see from the figure above, the glass is divided into 6 pieces of the same size. In other words, the LCD made from this glass is finally cut into 6 pieces, and the size of each piece is the final size. When the glass is cast, the specifications and sizes of each glass have been designed in advance.

Directional friction:Flannelette material is used to rub the surface of the layer in a specific direction so that the LCD molecules can be arranged along the friction direction of the aligned layer in the future to ensure the consistency of the arrangement of LCD molecules. After the alignment friction, there will be some contaminants such as flannelette thread, which need to be washed away through a special cleaning process.

After the TFT glass substrate is cleaned, a sealant coating is applied to allow the TFT glass substrate to be bonded to the color filter and to prevent LCD outflow.

Finally, the conductive adhesive is applied to the frame in the bonding direction of the glass of the color filter to ensure that external electrons can flow into the LCD layer. Then, according to the bonding mark on the TFT glass substrate and the color filter, two pieces of glass are bonded together, and the bonding material is solidified at high temperatures to make the upper and lower glasses fit statically.

Color filters are very important components of LCD panels. Manufacturers of color filters, like glass substrate manufacturers, are upstream of LCD panel manufacturers. Their oversupply or undersupply can directly affect the production schedule of LCD panels and indirectly affect the end market.

As can be seen from the above figure, each LCD panel is left with two edges after cutting. What is it used for? You can find the answer in the later module process

Finally, a polarizer is placed on both sides of each LCD substrate, with the horizontal polarizer facing outwards and the vertical polarizer facing inwards.

When making LCD panel, must up and down each use one, and presents the alternating direction, when has the electric field and does not have the electric field, causes the light to produce the phase difference and to present the light and dark state, uses in the display subtitle or the pattern.

The rear Module manufacturing process is mainly the integration of the drive IC pressing of the LCD substrate and the printed circuit board. This part can transmit the display signal received from the main control circuit to the drive IC to drive the LCD molecules to rotate and display the image. In addition, the backlight part will be integrated with the LCD substrate at this stage, and the complete LCD panel is completed.

Firstly, the heteroconductive adhesive is pressed on the two edges, which allows external electrons to enter the LCD substrate layer and acts as a bridge for electronic transmission

Next is the drive IC press. The main function of the drive IC is to output the required voltage to each pixel and control the degree of torsion of the LCD molecules. The drive IC is divided into two types. The source drive IC located in the X-axis is responsible for the input of data. It is characterized by high frequency and has an image function. The gate drive IC located in the Y-axis is responsible for the degree and speed of torsion of LCD molecules, which directly affects the response time of the LCD display. However, there are already many LCD panels that only have driving IC in the X-axis direction, perhaps because the Y-axis drive IC function has been integrated and simplified.

The press of the flexible circuit board can transmit data signals and act as the bridge between the external printed circuit and LCD. It can be bent and thus becomes a flexible or flexible circuit board

The manufacturing process of the LCD substrate still has a lot of details and matters needing attention, for example, rinse with clean, dry, dry, dry, ultrasonic cleaning, exposure, development and so on and so on, all have very strict technical details and requirements, so as to produce qualified eyes panel, interested friends can consult relevant technical information by a search engine.

LCD (LC) is a kind of LCD, which has the properties of light transmission and refraction of solid Crystal, as well as the flow property of Liquid. It is because of this property that it will be applied to the display field.

However, LCD does not emit light autonomously, so the display equipment using LCD as the display medium needs to be equipped with another backlight system.

First, a backplate is needed as the carrier of the light source. The common light source for LCD display equipment is CCFL cold cathode backlight, but it has started to switch to an LED backlight, but either one needs a backplate as the carrier.

CCFL backlight has been with LCD for a long time. Compared with LED backlight, CCFL backlight has many defects. However, it has gradually evolved to save 50% of the lamp and enhance the transmittance of the LCD panel, so as to achieve the purpose of energy-saving.

With the rapid development of LED in the field of lighting, the cost has been greatly reduced.LCD panels have also started to use LED as the backlight on a large scale. Currently, in order to control costs, an LED backlight is placed on the side rather than on the backplate, which can reduce the number of LED grains.

On the transparent diffuser plate, point-like printing can block part of the light. The LED backlight on the side drives the light from the side of the diffuser plate, and the light reflects and refracts back and forth in the diffuser plate, distributing the light evenly to the whole surface. Point-like printing blocks part of the light, screening the light evenly like a sieve.

At the top of the diffusion plate, there will be 3~4 diffuser pieces, constantly uniform light to the whole surface, improve the uniformity of light, which is directly related to the LCD panel display effect. Professional LCD in order to better control the brightness uniformity of the screen, panel procurement, the later backlight control circuit, will make great efforts to ensure the quality of the panel.

Since the LCD substrate and the backlight system are not fixed by bonding, a metal or rubber frame is needed to be added to the outer layer to fix the LCD substrate and the backlight system.

After the period of the Module, the process is completed in LCM (LCDModule) factory, the core of this part of the basic does not involve the use of LCD manufacturing technology, mainly is some assembly work, so some machine panel factories such as chi mei, Korea department such as Samsung panel factory, all set with LCM factories in mainland China, Duan Mo group after the LCD panel assembly, so that we can convenient mainland area each big monitor procurement contract with LCD TV manufacturers, can reduce the human in the whole manufacturing and transportation costs.

However, neither Taiwan nor Korea has any intention to set up factories in mainland China for the LCD panel front and middle manufacturing process involving core technologies. Therefore, there is still a long way to go for China to have its own LCD panel industry.

LCD vs DLP technology: What are the differences between these resin 3D printing technologies? The liquid resin is contained within a vat, or tank, cured against a build platform, which slowly rises out of the tank as the part is formed, layer by layer. These two 3D printing technologies are quite similar, but here is the main difference: the light source.

LCD printing: A UV light coming from an array of LEDs shining through an LCD flashes complete layers at the resin tank. A screen is used to mask the entire image, only revealing the current layer for curing. LCD 3D printing is a cost-effective resin manufacturing technique to get big and detailed functional parts. This 3D printing technology focuses on mass manufacture and large component 3D printing for resin materials thanks to 3D printers with larger build tray developed by Photocentric for example.

DLP printing: The digital light projector is the light source of DLP 3D printers. The DMD (Digital Micromirror Device) is a component made of thousands of micromirrors that are contained within a semiconductor chip matrix. These micromirrors are used for navigating the light beam projected by the digital light projector.

Or remove the resin tank, clean the LCD panel and the bottom of the resin tank film; wipe them with alcohol and then with a dry paper towel. (Note: touch ONLY the glass part of the screen, the area covered with black tape should not be touched).

Replace the Resin Tank if there is any damage. Remove the Resin Tank and clean the surface of the LCD and the underside of the Resin Tank, wipe first with alcohol, then with a dry paper towel (note that you can only touch the glass portion of the screen and avoid pressing against the black tape).Increase cooling time appropriately

There are two ways how to perform a factory reset. The procedure depends on your firmware version. First, find out your firmware version number by navigating to LCD menu - support - Firmware. Once you know the version number, use the corresponding instructions below. We recommend keeping your printer"s firmware up to date.

Immediately press and hold the Control knob until "Factory reset" is displayed on the LCD display (after 2-3 seconds). Depending on your settings, you will also get a sustained beep.

Digital light processing (DLP) and liquid crystal display (LCD) 3D printing have similarities to stereolithography (SLA) 3D printing; each of these technologies uses a light source to cure the resin. A projector is used to cure photopolymer resins in DLP printing and UV LEDs are projected through and LCD screen for LCD 3D printing.

The process of printing using these technologies can be “top-down” or “bottom-up”. In “top-down” printing, the object being printed is lowered into the resin and returns to one layer lower than previous after each layer is cured. In “bottom-up” printing, the object being printed is pulled out of the resin and returns to one layer higher than the previous after each layer is cured. The process is repeated layer by layer until the shape is built.

Far more than just a device able to make calls, send emails, play music, take pictures, and share those pictures on social media, cell phones are capable of amazing feats when paired with 3D printing. They can be turned into microscopes and other medical devices, and even be used to power a 3D printer. But another trend that’s picking up steam is using your smartphone as an actual 3D printer.

Back in 2015, researchers from MIT were working to develop new algorithms that could harness polarized light from smartphones for 3D printing. That very same year, we first heard about the OLO (now called the ONO), the world’s first smartphone 3D printer. 2015 was clearly an important time for this type of work, as a professor of mechanical engineering at Taiwan Tech also created a smartphone-based 3D printer that year. In just about all of these cases, light emanating from the phone’s screen was used to cure resin, rather than using UV lights.

“Instead of using a laser or a projector to cure the polymer, we use unmodified LCD screens and our specially formulated Daylight polymer,” the company’s website reads. “All other 3D printers that polymerise resin use a combination of both daylight and UV light at considerably higher intensities. We have been able to make this work by developing the world’s most sensitive daylight resins. Utilising mass produced screens designed for use in mobiles, handheld devices enable us to use the highest resolution screens, offering phenomenal value for money, which we can then pass on to our customers. The opportunities are limitless; higher and higher resolution screens becoming available in all formats from mobiles to large format televisions provide the lowest cost imaging systems ever imagined. We call this Daylight Polymer Printing.”

While 3D printing is used for both small-scale and large-scale manufacturing across many industries, Photocentric, which holds patents in visible light curing technologies, believes that the technology still costs too much to be adopted on a wide scale. That’s why the company is focused on using the LCD screens we interact with every day on our TVs, smartphones, laptops, and tablets to transform 3D printing and make it less expensive.

To 3D print an object with resin-based 3D printers, the material is typically cured and hardened with a laser, or a digital light projector. But Photocentric is using LCD screen illumination to lower the cost of 3D printing, so that the technology can be used in more applications.

Now, Photocentric is totally focused on powering 3D printing using the illumination from LCD screens, mostly from the visible part of the spectrum, which is required when it comes to visual display screens. This could be the future of industrial 3D printing someday.

“Today it seems obvious that the highest resolution, largest format and lowest cost digital light source available is the visual display screen we all use in our pockets or on our walls,” said Paul Holt, the Founder of Photocentric. “But it can only work in 3D printing because our photopolymers can harden in light within the visible spectrum.

“We are now doing research into all formats of 3D printers with LCD screens from the nano – using tiny screens from near-eye virtual reality headsets – through to mobiles, tablets, right up to the largest TV screens. In fact, we just won a grant to manufacture what will be the largest 3D printer in the world, based on a 98-inch HDTV screen. Our goal is to change world manufacturing, not just 3D printing, by making 3D printing low cost, large scale and functional.”

In terms of making the technology more affordable, there are millions of LED screens manufactured by the electronics industry. It seems like nearly every quarter, cell phone, tablet, and TV screens change in size and affordability. If this industry takes its cue from Photocentric and focuses its R&D efforts on using these screens for 3D printing, the technology will inevitably become less expensive.

However, don’t expect to use your cell phone’s LCD screen to make large 3D printed objects. Regardless of how ingenious the idea is, the light output will likely be pretty low, and not enough to fabricate big parts. But it could be helpful when 3D printing lots of smaller objects.

“This time we are using light and a binder to fix the shape of a metal rich formulation using light from LCD screens,” Holt explained. “The object will then be slowly heated to remove the binder and sinter (fuse together) the metal. This technology can then be applied to all small-volume manufacturing of metal parts.”

While 3D printing in metal could eventually have a major impact on materials manufacturing, the 3D printing work that Photocentric is doing with metals is still mostly confined to the lab and is not a working solution just yet.

Verify the machine is powered ON. The Brother machine has an ON/OFF button located on control panel of the machine. If machine is OFF, the display will be blank.

If the display is still blank, try to tilt or move up or down the LCD display and also try a different known working electrical outlet at your location.

If what Thomas Sanladerer states is correct, the Mars 2 Pro (monochrome LCD, no color filter) has a layer time approximately 1/3 as long as the Mars/Pro printers (where color LCDs are used):

This would indicate that the light passing through the LCD, when the color filter is present, is 1/3. Put it in other words, only ONE subpixel is capable of transmitting UV light.
