As we all know, LCD touch screen is widely used in our life, in fact, different fields do not have the same requirements and characteristics of the LCD touch screen.
Various applications of touch screen requirements:
1. Industrial control:
Gloves, water, chemical environment, impact resistance, anti-fouling, easy to clean and other requirements, the use of touch screen power environment is to consider the strict requirements of interference common position and long-term energy reliability issues.
2. The use of financial stations:
The general long service life, the requirements of safety and reliability. Among them, the office financial station also has a long-term energy needs.
3. Outdoor touch screen advertising:
Generally sunlight readable, waterproof, anti-shedding.
4. Smart home kitchen applications:
Need to consider the safety glass and high temperature requirements.
5. Smart home appliance applications:
Need to consider product safety and black requirements.
6. Airborne applications: Need to consider the reliability of the service life, optical requirements (AG, AR) as well as safety and anti-collision requirements.
LCD touch screen common failure is the LCD screen problems, black band, line is the most common, you can summarize the basic problems of these LCD, some are repair conditions, some are due to high temperature, resulting in COF and liquid crystal contact ACF chapter. This phenomenon can be solved by the hot medium under the flat iron head.
LCD devices, screen components and inverter circuit board (high-voltage board) is a multi-shot failure, performance is like turning on a lamp, but instantly no lamp, but there is sound, only SHARP, but the lamp aging and damage will result in order to protect the high-voltage board, eliminate the high-voltage board to compare the medium in the feedback circuit to determine whether the lamp or high-voltage board itself is damaged.
LCD how to repair, in fact, the ordinary LCD is the same, in the repair list, you can see the error elements, there are error codes, some direct zero code, some repair location corresponding error.
Different places, different industries have certain requirements for the parameters of the LCD screen, outdoor sunlight, high brightness LCD screen suitable for outdoor use, high temperature work needs to be resistant to high and low temperature LCD screen. So, when choosing an LCD screen, according to their needs! If you have questions about the LCD LCD screen, you can contact SONYTEK to learn more about the LCD screen knowledge.
