Application scenarios of flexible OLCD


Multiple design possibilities


     LCD displays are widely used, but the limitations of their pure flat surfaces make engineers limited by displays from the very beginning when designing products. Electronic products usually have to be designed according to the planar characteristics of the display, which is a bit of a cart before the horse. Since flexible substrates are easy to cut, using these substrates to replace glass eliminates this design constraint and provides many opportunities to create displays with unique display shapes and curved surfaces.


 


Smart home device


     The glass-free OLCD is easily processed into a convex or concave surface, and the downward bending radius can reach 10mm without affecting the toughness of the display. For example, high-end smart speaker products on the market are now equipped with displays, but these flat glass screens are a compromise between integrating displays and integrating them into the overall product design. Using OLCD enables the display to be designed in the shape of a "surround" speaker, thereby creating a new audiovisual use case effect.


Notebook and tablet computers


     The cost structure of a flexible OLCD is similar to that of a glass LCD-except for glass, it uses many of the same low-cost components, which reduces the weight of the laptop display by 100g and the thickness by 0.5mm. In addition, OLCD can also realize borderless displays, allowing notebook computers and tablet computers to have larger displays without increasing weight.


TV and monitor


    LCD TVs are relatively low-cost and dominate the TV market, but they cannot achieve the ultra-high contrast performance of OLED TVs. The latest development of glass LCD technology is to form a dual-cell LCD by stacking two LCDs on top of each other to improve LCD contrast. Although this method significantly improves the contrast of the display, the need for four glass plates increases the thickness of the display and also increases the cost of the module. It also requires brighter backlighting and cannot provide true pixel-level dimming. .



     The use of dual display unit OLCD technology can overcome the problems of increased thickness and lack of true pixel-level local dimming. The TAC film that builds the OLCD is ten times thinner than glass, which means that the two display units can be gathered together at a much smaller pitch than the pixel pitch of a TV. In addition, the display architecture becomes thinner, and can be manufactured in a simpler way (compared to dual-cell glass LCD or OLED), at a lower cost, and with higher optical performance.


Digital billboard


     When the screen is made of glass, weight becomes an important consideration for large display devices, because large displays usually require a sturdy support frame or frame, which limits the location and way of installing glass displays in buildings and on top of objects. OLCD technology has all the benefits of LCD technology as an advertising selling point in terms of brightness, color performance, video transmission rate and cost, and its significant advantage is that it does not require glass, is thin and fits well. OLCD technology can be extended to large-size displays, and even large digital billboard displays can be integrated with pillars, street furnishings, vehicle exterior design and retail store interiors.
