LCD bonding machine, widely used in the Phone/TV/Watch/Touch panel products produce and repairing area.
LCD Liquid crystal display (LCD) is LCD panel that is widely used in mobile phones, LCD, LCM and other production processes. Is composed of two glass sheets laminated together, the middle is LCD, the lower plate is TFT circuit, the board is RGB and subsidiary structure, Glass is called a glass substrate when the lcd production, which not been cut is called Glass, a process finished cutting called CELL.
LCD GLASS can be divided into TN, VA, IPS, CPA and many other types. Can largely determine the brightness of the LCD display, contrast, color, viewing angle and speed the development of LCD panel soon , the part of LCD panel with liquid crystal displays are very closely linked, its production and market environment, the pros and cons variety of factors related tothe quality of the liquid crystal display , price and market trends, as an LCD display for about 80 percent of its costs are concentrated in the panel.
LCD panel used in digital watches and clocks, and many display type of portable computer.LCD display to use two pieces of polarized materials, is a liquid crystal solution between them.Current by rearranging will make the liquid crystal, so that the light can’t through them.As a result, each crystal is like a shutter, both can allows light to pass through and can block the light.
Liquid crystal display (LCD) technology information Towards the target OF thin, short, small development, display with a long history in computer peripheral products, of course, is no exception.Under easy to carry and transport for the former title, the traditional way of display, such as the CRT image tube display and LED display boards, etc., are subject to the volume is too large or giant factors such as power consumption, unable to reach the user’s actual demand.And the development of liquid crystal display technology is to the current trend of the information goods, whether it is right Angle display, low power consumption, small volume, or zero radiation, etc, can let users enjoy the best visual environment.

ACF Tape is normally made up of two main components, namely Adhesive & conductive particles.
Adhesives
The adhesive composition is dependent on the materials being assembled. This means an ACF designed for use in a flex-on-glass (FOG) assembly is usually not suitable for use in a chip-on-glass (COG),chip-on-film(COF), flex-on-board(FOB),flex-on-flex(FOF) or any other configurations. It is specific to the application for which it is designed for.
ACF Conductive Particles
Conductive particles are used to conduct electricity from one side of the bond to the other. Depending on the application, conductive particles range from 3.5μm to 30μm in size, and can be made from Nickel-gold plated polymer spheres, gold plated nickel particles, or lead-free solder materials. Particles may be individually coated with a outer polymer to insulate them from other uncrushed particles, but which will crack open and allow electrical conduction if the particle is trapped and crushed between two pads during assembly.
ACF TAPE
ACF (Anisotropic conductive film) or ACF tape is an epoxy adhesive system used by electronics industry to make electrical and mechanical connections from drive electronics to substrates.
ACF are filled with conductive particles which provides electrical interconnection between pads through the film thickness (z-direction).
The conductive particles are distributed far apart thus not electrically conductive in the plane direction (X&Y) of the film.
ACF interconnect offers cost savings by substituting conventional mechanical connectors or soldering interconnect.
ACF interconnect allows low height and fine pitch which enables high density and miniaturizing of assembly.
ACF special conductive particle is made from environmental friendly material (ROHs compliance). It provides good metalic bonding.
Similar to Silicone rubber, Teflon tape is often used to provide evenly distributed pressure and temperature on the ACF bonding process.

COF bonding machine accessories
Welcome to buy the COF bonding machine and all the COF bonding machine accessories.
OLED panel bonding machine, is for AMOLED panel produce and repair machine for TV/Cell phone/Watch/other AMOLED products. bonding the COFs on the OLED panel and flexible FPCs.
An organic light-emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. This organic layer is situated between two electrodes; typically, at least one of these electrodes is transparent. OLEDs are used to create digital displays in devices such as television screens, computer monitors, portable systems such as smartphones, handheld game consoles and PDAs. A major area of research is the development of white OLED devices for use in solid-state lighting applications.
There are two main families of OLED: those based on small molecules and those employing polymers. Adding mobile ions to an OLED creates a light-emitting electrochemical cell (LEC) which has a slightly different mode of operation. An OLED display can be driven with a passive-matrix (PMOLED) or active-matrix (AMOLED) control scheme. In the PMOLED scheme, each row (and line) in the display is controlled sequentially, one by one,whereas AMOLED control uses a thin-film transistor backplane to directly access and switch each individual pixel on or off, allowing for higher resolution and larger display sizes.
An OLED display works without a backlight because it emits visible light. Thus, it can display deep black levels and can be thinner and lighter than a liquid crystal display (LCD). In low ambient light conditions (such as a dark room), an OLED screen can achieve a higher contrast ratio than an LCD, regardless of whether the LCD uses cold cathode fluorescent lamps or an LED backlight.
The different manufacturing process of OLEDs has several advantages over flat panel displays made with LCD technology.
OLEDs can be printed onto any suitable substrate by an inkjet printer or even by screen printing, theoretically making them cheaper to produce than LCD or plasma displays. However, fabrication of the OLED substrate is currently more costly than that of a TFT LCD. Roll-to-roll vapor-deposition methods for organic devices do allow mass production of thousands of devices per minute for minimal cost; however, this technique also induces problems: devices with multiple layers can be challenging to make because of registration – lining up the different printed layers to the required degree of accuracy.
OLED displays can be fabricated on flexible plastic substrates, leading to the possible fabrication of flexible organic light-emitting diodes for other new applications, such as roll-up displays embedded in fabrics or clothing. If a substrate like polyethylene terephthalate (PET)can be used, the displays may be produced inexpensively. Furthermore, plastic substrates are shatter-resistant, unlike the glass displays used in LCD devices.
OLEDs enable a greater contrast ratio and wider viewing angle compared to LCDs, because OLED pixels emit light directly. This also provides a deeper black level, since a black OLED display emits no light. Furthermore, OLED pixel colors appear correct and unshifted, even as the viewing angle approaches 90° from the normal.
LCDs filter the light emitted from a backlight, allowing a small fraction of light through. Thus, they cannot show true black. However, an inactive OLED element does not produce light or consume power, allowing true blacks. Removing the backlight also makes OLEDs lighter because some substrates are not needed. When looking at top-emitting OLEDs, thickness also plays a role when talking about index match layers (IMLs). Emission intensity is enhanced when the IML thickness is 1.3–2.5 nm. The refractive value and the matching of the optical IMLs property, including the device structure parameters, also enhance the emission intensity at these thicknesses.
OLEDs also have a much faster response time than an LCD. Using response time compensation technologies, the fastest modern LCDs can reach response times as low as 1 msfor their fastest color transition, and are capable of refresh frequencies as high as 240 Hz. According to LG, OLED response times are up to 1,000 times faster than LCD,putting conservative estimates at under 10 μs (0.01 ms), which could theoretically accommodate refresh frequencies approaching 100 kHz (100,000 Hz). Due to their extremely fast response time, OLED displays can also be easily designed to be strobed, creating an effect similar to CRT flicker in order to avoid the sample-and-hold behavior seen on both LCDs and some OLED displays, which creates the perception of motion blur.
