Analog resistive-type touch screen series.
Providing solutions for the attachment of touch screens to liquid crystal displays
Touch screen and liquid crystal sets
We offer LCD, touch screen, and controller sets as well as semi-customization for bonding. DMC provides high-quality factory-made LCD modules with touch screens.
Choice of liquid crystal displays
We respond to requests for the bonding of DMC touch screens to a wide range of small to large liquid crystal displays from different manufacturers. We are also happy to accept liquid crystal displays provided by the customer.
What is air bonding?
When bonding clear screens or touch screens to liquid crystal displays, a small space is created between the modules. Air bonding technology bonds the two units with double-sided tape to prevent dust and moisture from entering.
Ease of implementation
Although the bonding of touch screen to a liquid crystal display with double-sided tape is a routine procedure, it must be done in a clean room to provide anti-bacterial treatment and prevent dirt and dust.
Air bonding is a simple and cost-effective process using equipment to bond the touch screen to the liquid crystal with double-sided tape. Small-lot production in a clean room does not require equipment for processing.
What is optical bonding?
Optical bonding is applied to fill the small gaps between the touch screen and liquid crystal module on the display, or liquid crystal module and clear screen using resin (optical elasticity resin).
Bonding of a clear screen to a liquid crystal module minimizes the light refractive index to maintain high visibility. It is ideal for images that must be especially bright and information displays in disorderly or bright sites.
Bonding of a clear screen to a liquid crystal display with resin reduces the light refractive index generated when the air space and screen are permeated, and prevents reflection on the screen.
Inserting optical elasticity resin into the air space increases the physical strength of the display surface. Having no gap between liquid crystal display and touch screen prevents damage from foreign matter such as dust and moisture. It is ideal for FA and equipment used by general public.
Moisture in the space between liquid crystal and touch screen may cause condensation in environment that experience wide changes in temperature. Filing the air space with resin prevents condensation to ensure good visibility. It is ideal for use in environments that have significant changes in air pressure such as transport vehicles, aircraft, storage spaces, and laboratories.
Improved input precision
The thickness of the touch screen may cause parallax between images on the screen and the actual touch points, which can result in gaps when entering data with the touch pen. Optical bonding allows users to easily confirm and match the touch point with the image, which supports natural touch entry regardless of parallax.
