What's the feature and purposes of LOCA?

Image
Liquid optically clear adhesive (LOCA) is liquid-based bonding technology used in touch panels and display devices to bind the cover lens, plastic, or other optical materials to the main sensor unit or each other. These adhesives improve optical characteristics and durability. Primary advantages of LOCA compared to other adhesives are its: ·Re-workablility ·Adhesion to non-even surfaces ·Superior optical properties ·Durability LOCA follows traditional die-cut film adhesives, also known as optically clear adhesives (OCA tape). LOCA also allows for thinner designs and new technologies, such as the use of silicone, improve the properties of the final product. Feature: 1. Peeling caused by outgas from plastic is restrained. 2. Heat and humidity resistance (prevents haze increase). 3. Excellent adhesion to difficult-to-adhesive surface (such as hard coated surface). 4. Gap-filling ability to fill the printing gap.

Which Is Better: TFT or LCD?

TFT stands for "thin-film transistor." LCD stands for "liquid crystal display." Both terms refer to the flat-panel display, or screen, of a computer monitor or television set. TFT v. LCD LCD is a generic term. A TFT display is one kind of LCD. Differences TFT displays are made using large sheets of transistors, each one of which is controlled independently. A TFT screen is an "active-matrix" screen where each pixel of the display is illuminated individually. Sharpness and Speed A TFT display is sharper and brighter than a common LCD display. It refreshes more quickly than a regular LCD display and shows motion more smoothly. Power Usage TFT displays use more electricity than regular LCD screens, so they not only cost more in the first place, but they are also more expensive to operate. Conclusion A TFT display is much higher quality than a regular LCD display. It is a better display in every way, except that it is more ex

What does In-Cell Technology mean?

Image
In-cell technology refers to a standard of displays that emerged in 2012 and allow mobile devices, such as smartphones, to have thinner form factors. They also allow devices to keep a low weight even when the display increases in size. The term in-cell display emerged in 2012 in reports that Apple's successor to the iPhone 4S would include this new technology , thus reducing the thickness of the screen. In-cell displays are revolutionary in the sense that they combine a digitizer, use touch input, and integrate an LCD screen into a single-layer display . Some reports also suggest that in-cell technology displays provide better resolution compared to standard LCD screens.

What‘s different from IPS matrices and TN Film panels?

Image
In Plane Switching (IPS - also known as 'Super TFT') technology was developed by Hitachi in 1996 to try and solve the two main limitations of TN Film matrices at the time, those being small viewing angles and low-quality color reproduction.  The name In-Plane Switching comes from the crystals in the cells of the IPS panel lying always in the same plane and being always parallel to the panel’s plane (if we don’t take into account the minor interference from the electrodes).  When voltage is applied to a cell, the crystals of that cell all make a 90-degrees turn. By the way, an IPS panel lets the backlight pass through in its active state and shutters it in its passive state (when no voltage is applied), so if a thin-film transistor crashes, the corresponding pixel will always remain black, unlike with TN matrices. IPS matrices differ from TN Film panels not only in the structure of the crystals, but also in the placement of the electrodes – both electrodes are on
