Display developement

Display was developed from 1st generation, CRT to 2nd generation display(PDP, LCD). Now, it is being developed to 3rd display, OLED and flexible display.

Development of Display

A Liquid Crystal which is a core component of LCD blocks or passes light. However, since the liquid crystal is not able to emit light by itself, it needs a backlight which can change the elecric energy to the light energy for showing visual information on the LCD panel.

Because the OLED, the next generation display of the LCD uses light emmiting diodes, it needs less elements such as backlignt unit, color filters and has simpler structure than the LCD. Therefore, the OLED is lessened the thickness and the weight one third of LCD and has excellent image quality and less power consumption. Also, plastic materials can be used for OLED to implement various forms like flexible and bendable displays.

Now, the smartphone market using AMOLED has been rapidly grown and captures the OLED market. However, accrording to the development of IoT technology including automotive, demands for various forms of displays are increasing. In addition to this, the development for large size and flexible OLED, we expect the change of display paradigm and huge growth.


Semiconductor Equipment


Semiconductor is a core component for all IT products and it is widely used for computers, communication equipments and systems, automobiles, digital home appliances, industrial machines, control systems and so on. In particular semiconductors are core components of digital products which are major export goods of Korea. The semiconductor industry is a higher value-added business that effects a lot on improvement of national competitiveness and the national core strategic business that creates demand and technological advancement at the same time.

Semiconductors are classified into two types, memory semiconductor and non-memory semiconductor(system semiconductor).

Memory semiconductors that store and recall information are classified into volatile(RAM) and non-volatile(ROM) semiconductors. A RAM chip requires a constant source of power to retain information so when power is lost or turned off, it will lose the information stored on it. In contrast, when power is lost or turned off, a ROM keeps the information stored on it.

On the other hand, non-memory semiconductor is made for data processing such as control, conversion, arithmetic operation and so on. Microcomponent, logic IC, optical semiconductor, analog IC are non-memory semiconductors.

As digital devices become mobile and smart and automobiles, medical machines and industrial machines are developed based on the internet, the environment around the semiconductor industry is getting more friendly.

Semiconductor manufacturing processes are devieded into three major processes. The first step is to cut a single-crystal ingot into thin slices and develop masks. The second step is a front-end that is to manufacture integrated circuits and complete making chips. The last step is a back-end which is to perform cutting chips, packaging and test.

Packaging(include test) is a process that allows an electrical connection to the chip and makes physical function and shape to make the chip endure external shock.

As electronic goods become lighter, thinner, shorter, smaller and more multifunctional, minimalized and high density packaging technologies are developed. This trend makes semiconductor packaging technology more important.

DE&T has developed Laser Bonder to allow electrical connections to chips in the packaging process and gradually expands its product family.

Automotive Electronics


An automotive components industry which dominates automobile industry has huge effects on the rear industries such as material, electric and electronic industries. It plays a pivotal role for the national economy from export and current account to employment so it has a great ripple effect on related industries.

Automotive components are frame, engine, powertrain, suspension, steering system, break system, air-conditioning &heating equipment electronic equipment, and so on. Automotive electronics mean all electric and electronic systems in the car.

Trend of automotive electronics is due to the demand for safe, convenient and environmental friendly cars. Automotive electronics are mainly devided into three parts that are electrical devices of powertrain, safty systems such as a lane departure prevention system and an airbag and equipments for convenience like telematics.

Electronics components and softwares that exchange electrical signals to move vehicles are core cutting-edge technologies in the field of automobile market such as unmanned vehicles under development. Also,as governments of many coutries strenthen their regulations on environment and safety, related products are constantly being installed in vehicles. In addition, demands for more convenience is getting increasing, Manufacturers are actively introducing electronics technology. These electronics components are controlled by automotive semiconductors and are acount for 40% of the automobile manufacturing cost and are expected to grow even more.

DE&T develops and produces automotive electronics including Automation Equipment for Production of Automotive Components.
