Entering the World of OLED

An Organic Light-Emitting Diode (OLED) is a semiconductor device based on organic materials. It is made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. It has a number of advantages. For example,  the property of self-emitting makes it colorful, high contrast and can present realistic and clear picture. OLED screens are so thin and soft that can be bent, folded and be used to make a variety of innovative products. Meanwhile, they consume less energy that can effectively save power.

An OLED display can be driven with a AMOLED (active-matrix) or PMOLED (passive-matrix) control scheme. The AMOLED has longer lifetime, and the picture quality is high, full color, high contrast, and high efficiency, but more expensive and complicated. Therefore, it is suitable for full color OLED display products with large size, high resolution and high information capacity. PMOLED has a shorter pixel lifetime and limited resolution, but it is more suitable for simple and small-sized display devices because of its low cost and simple manufacturing process.

The production equipments of Cover Glass for TFT displays, OLED displays and Monochrome displays

Image
Cover glass production equipment, Roller coater, Cutting machine, Glass carved machine, Automatic surface sweeper, Curved surface sweeper, Automatic toughening furnace.    1. A roller coater is a highly efficient piece of equipment that is applied to coat glass surfaces. Its product structure mainly includes a conveyor belt system, coating fluid storage tank, coating roller device, drying device, and control system. The working principle is when the glass enters the coating tank through the conveyor belt, the coating liquid is coated evenly on the glass through the roller. In the next step, glass passes through a drying device， the quality control and output by a control system. This equipment achieves mass production with its efficient and continuous working method, it takes advanced coating technology to ensure the effection of drip-free and spot-free and quality. 2. The cutting machine is mainly applied to cut the ...

COG and COF in Display Sealing Technology

Image
Sealing refers to the connection and encapsulation of a display driver IC with a glass or film substrate, so it is called a bridge between the internal IC world and external circuits, and mostly used in display technology . In the field of sealing technology, COG (Chip on Glass) and COF (Chip on Film) are two common and important technologies. Chip on Glass (COG) is to place the driver IC directly on the glass substrate. It makes the driver IC under the LCD and helps to reduce the size of the LCD module, but squeezes the screen space, resulting in a wide bezel and a small screen area. The key of this technology is to realize the connection between the driver IC and the glass by using anisotropic conductive adhesive or hot pressing. The advantage includes simple structure, lower cost, and the ability to achieve a high degree of integration. However, COG may be subject to space constraints when the IC size is large and requires higher requirements for the production of fine line...
