LOCA glue for Tempered glass

Henkel’s liquid optically clear adhesives (LOCA) can be supplied in 1 component system and cured under UV or visible light (1K). Since the liquid adhesive cures instantly to a solid polymer when exposed to UV or visible light, the improved process efficiency can be expected as well.

The CCD was invented in 1969 at Bell Labs by Willard Boyle and George Smith[1]. Since that CCD was sensitive to light it was used as image sensor for video and TV cameras. It could also be used as a memory device or analogue signal delay since it's principally a kind of analogue shift-register circuit. Thus the image information given in parallel to the whole pixel matrix during exposure is read sequentially by the camera's image processor after exposure.

In 1972 semiconductor maker Fairchild introduced the first experimental CCD for photography which made exposures of the format 100×100 pixels. Production was launched in 1974. In 1986 Kodak introduced the first 1 Megapixel CCD.

A different semiconductor technology used in sensors is known as CMOS. As this is more adaptable to providing video as well as still images, by about 2010 CMOS had come to dominate the consumer marketplace. CCDs remain the preferred technology for certain uses, such as scientific imaging. The 570-megapixel Dark Energy Camera uses specialized Dalsa CCDs for its astronomical observations.

The resolution of the image sensor governs the resolution of the camera, although some cameras can produce increased pixel counts using interpolation software - particularly with multi-CCD sensors.

Through-the-lens measuring techniques, especially distance measuring of autofocus systems rely on CCD components, even in analog SLRs. Light metering can also be based on a CCD as sensor.

Liquid optically clear adhesives from Henkel (LOCA) are used to help ensure high optical and bonding performance of the protective screen cover lens to the display. This may include bonding of different substrates such as plastic to plastic, plastic to glass, and glass to glass. LOCA can be applicable for free-formed and design displays, including curved designs.

The sensitivity to light of the sensor controls the ISO range that the camera can emulate. More sensitive sensors can also permit greater pixel bit widths, and so give better colour rendition.

Optically Clear Adhesivefilm

Many of the big camera makers or consumer electronics companies have their own CCD production facility, for example Sony and Fujifilm. Kodak was originally a leading company in sensor technology, providing high resolution CCDs for the likes of Leica[2]. During Kodak's collapse the CCD division was spun off under the name Truesense Imaging; and in 2014 this was acquired by ON Semiconductor[3]. Other companies specialise in making image sensors, among them Omnivision and Dalsa. Dalsa already offers a low-noise still camera CCD with 33 megapixels, still based on the above-mentioned Bayer pattern.

For example, Henkel’s newly developed PSA (pressure sensitive adhesive) LOCA can be used like a dual-side adhesive tape, however, there is no waste of separator films, no need of cutting process and can apply with fully automated process to any types of display design.

A CCD or Charge-Coupled Device is an electronic device that can be used as the image sensor in place of film in a digital camera, or in devices like microscopes, telescopes, and scanners. CCDs are also used for certain autofocus and light metering systems in film or digital cameras. A CCD is a rectangular semiconductor chip with a surface built of an array of light-sensitive areas (pixels). Each pixel is a kind of combination of photo diode for light-sensitivity and capacitor for analogue value storage. The charge levels for each pixel are read out sequentially and digitized by separate circuitry.
