OLEDs have primarily been known for burn-in effects. But does image sticking also occur in TFTs? The answer is yes. However, TFTs can recover with proper initialization. Panel manufacturers' tests typically involve displaying a checkerboard pattern…
During the Covid-related supply bottlenecks, many companies placed large orders for components and increased their inventory levels. These excess inventories are now being depleted amidst the current economic downturn, leading to a decrease in demand for LCDs, among other components. Consequently, manufacturers are responding by reducing their production capacities…
A crucial parameter in the evaluation and optimization of LCDs is the contrast ratio. If the contrast is too low, the image appears pale and washed out. However, if the contrast is set too high by increasing the VLCD, shadows or streaks can occur…
VA Technology for Passive LCDs - a Cost-Effective and Modern Alternative
Innovative e-paper design for design and architecture In brief ⏱ Estimated reading time: 1 minute E Ink Prism technology opens up new possibilities for designing surfaces with electronic paper. This is a special, flexible e-paper film that uses segmented...
A cost-effective alternative to monochrome vertical alignment displays is an LED-based solution. Beneath a printed front panel, bright LEDs are positioned, enabling the illumination of individual segments. For simple operating solutions with individual buttons or a few digits, it can…
We frequently receive customer inquiries regarding the diversification of their supply chains. Following the severe COVID-19 lockdowns, particularly in China, there is a growing consideration to mitigate risks by diversifying. Typical inquiries to date have been: It is fundamentally important to understand that most manufacturers of…
E Ink technology is rapidly advancing. An increasing number of colors can be displayed in progressively larger modules. Advanced Color EPaper can reproduce the entire color spectrum. In the future, advertising posters will no longer need to be manually replaced; instead, their content will be updated digitally. In the long term, this approach saves…
Task: When using night vision devices, light sources, including control elements such as LCDs and TFTs, must typically be switched off. Otherwise, users can be blinded, and the sensitivity of image intensifiers can be degraded by bright light sources. Some light leaks are so significant that…
As complex technical products composed of numerous diverse components, LCDs are subject to various regulations, such as REACh, RoHS, and those concerning the use of conflict minerals. Given the numerous REACh sunset dates for critical substances by the end of 2023, displays must also be regularly…
