Besides Samsung, the Chinese Huizhou-based electronic giant, TCL is also a major player in the smartphone display industry, specifically under its display department, the TCL China Star Optoelectronics Technology(CSOT) Corporation.
Recently TCL’s CSOT Department made a revolutionary display breakthrough for smartphones as the company has successfully developed ultra-thin active high privacy display technology. The technology is a mouthful to read but the science behind it is rather quite interesting.
Conventionally, those privacy screen protectors you currently see in the market utilise low refraction highly reflective material to ensure that the confidential content you are reading is protected from the surrounding people. However, there is one caveat to the current conventional privacy screen protectors on the market currently which is that it only reduces the visibility of the screen at certain angles, and at some angles, the content although difficult to read is still legible to the naked eye if someone were standing near to you.
This is because currently there are no inherent electronics inside your privacy screen protector, it is only a passive technology. TCL aims to solve the problem with active technology by instead changing the screen, instead of the screen protector. TCL aims to make the screen itself to be an active high privacy display.
Not only does the active privacy display boast better privacy-focused reflective angular efficiency compared to the passive privacy screen protectors, but also since the screen is utilising active technology, the display can change privacy modes with a simple click.
TCL has illustrated the technology as shown where the 13-inch laptop screen can change from a privacy screen to a normal screen instantaneously without changing the laptop’s orientation or viewing angle.
Currently, TCL has proudly exclaimed that its CSOT Display department has successfully developed the display technology for smartphones. The company is proud that with its team of engineers, it has achieved to produce an ultra-thin active high privacy 6.58-inch smartphone display.
At a 45 degree angle with privacy mode turned on, the nearest side-looker will not able to see your screen as with the display’s electronic configuration and chemical properties, the screen shall only let through 1.12% of the display’s light through to the side-looker. Despite all the technology crammed into the panel, this high privacy active smartphone display comes in at only 0.1mm thicker than your conventional smartphone AMOLED screen.
TCL mentions that the technology is currently at the end of its prototype testing phase, and the company is looking start production of these high privacy active displays very soon once it is ready.
