Silicone optical adhesive use in full fit of display screen

Silicone optical adhesive is commonly used in the full fit process of display screens, especially in applications where optical clarity and bonding strength are important. The full fit process involves attaching the display panel directly to the cover glass or touch sensor, eliminating the air gap between them.

Silicone optical adhesive offers several benefits in this application:

Optical Clarity: Silicone optical adhesives are specifically formulated to have high transparency and minimal light scattering. They are designed to minimize the refraction and reflection of light passing through the adhesive layer, ensuring optimal optical clarity and minimizing any visual distortion. This is crucial for maintaining the display’s image quality, color accuracy, and readability.


Bonding Strength: Silicone optical adhesives offer excellent adhesion properties, allowing them to form a strong and reliable bond between the display panel and the cover glass or touch sensor. They adhere well to a variety of materials used in displays, including glass, metal, and plastic surfaces. The adhesive’s high bond strength ensures that the components remain securely attached, even when subjected to mechanical stresses such as impacts or flexing.


Flexibility: Silicone adhesives have a certain degree of flexibility or elasticity, making them suitable for applications where the display panel or cover glass may undergo bending or pressure. This flexibility helps to absorb mechanical shocks and vibrations, reducing the risk of damage to the display and maintaining the integrity of the adhesive bond. It also allows for the use of silicone adhesives in curved or flexible display designs.


Thermal Stability: Display screens can generate heat during operation, especially in devices with high-performance components. Silicone optical adhesives exhibit good thermal stability, meaning they can withstand a wide temperature range without significant degradation. They retain their adhesive properties and optical clarity even under elevated temperatures, ensuring long-term reliability and performance.


Moisture and Chemical Resistance: Silicone optical adhesives have inherent resistance to moisture, humidity, and many chemicals. This property protects the display components from environmental factors that could potentially degrade their performance or cause damage over time. The adhesive acts as a barrier, preventing moisture or contaminants from reaching the sensitive electronics or optical elements of the display.
