What is OLED?

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 smartphoneshandheld 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.

OLED Advantages

The different manufacturing process of OLEDs has several advantages over flat panel displays made with LCD technology.

Lower cost in the future

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.

Lightweight and flexible plastic substrates

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.

Better picture quality

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.

Better power efficiency and thickness

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.

Response time

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.

Bonding Machine

Bonding Machine, is the widely used machine in the LCD/LED/OLED, LCM/open cell/panel/screen/display produce factories and repairing service shops all over the world.

The Bonding Machine is based on the recent innovations as well as planned to repair the arrangements of LCD, LED,OLED, TV/television, Laptop, Pad, Cell phone, Watch, Touch Panel, Ad Player, and all the flat and edge screens.

The Bonding Machine may consist of HD Digital Microscope, and also has a Digital Pressure Gauge, and vacuum generator which may help to hold the panel during the bonding process. The bonding press head may press the IC/FPC/COF onto the Glass/PCB/FPC using ACF conductive adhesive as medium, by a certain temperature, pressure and time. also some bonding machine use the Solder paste as the medium.

The Bonding Machine use the ACF tape as the medium ,so it also named ACF bonding machine.

ACF bonding machine

According to different LCD/LED/OLED and different screens, there are many ACF tapes models.  ACF tape is the important medium of the bonding process.

What is ACF?

ACF Tape/ACF Film  & Applications

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 or ACF (Anisotropic Conductive Film)

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.

What is ACF Bonding?

During ACF bonding, a combination of heat & pressure is applied on to chip (FPC/IC) for an appropriate time.

Conductive particles (each 3~30um) are compressed between IC and substrate (glass / PCB) while insulating materials pushed away.

This allows the compressed Ni-Au layer on the particles to conduct electricity between the IC and the substrates (z-axis).

The insulated particles are distributed with a minimum chance of electrical shorting in the x-axis and y-axis.

As the epoxy cures and conductive particles are trapped into permanent compressed form.

The compressed particles, by its elastic nature, are constantly pushing outwards to maintain good electrical conductivity under different environmental conditions.

ACF Bonding Machine Applications

ACF has for many years, been used in glass display applications. Recently, it is also becoming widely used in TAB,COG,FOG,FOB,FOF,COF,COB areas.
