TCL unveils low-power In-Cell HVATouch technology as a new and advanced form of touch-enabled LCD
Currently, 2 of the most prominent forms of touch-responsive LCD screens are known as on-cell and in-cell panels. The former has a layer responsible for registering the user's input and others to reproduce the display contents. The latter, on the other hand, combine the two, and may therefore have reduced latency, be clearer and make for thinner or more portable devices as they result in thinner panels overall.
On the other hand, in-cell (or 'integrated') panel production requires a different, updated production process compared to that for non-touch LCDs, which might impact negatively on a manufacturer's bill of materials or ability to order in larger volumes.
TCL claims to have developed a new way around both issues with its first-gen In-Cell HVATouch solution. It also integrates the touch-sensitive layer with the rest of the display, and also has a LargeTouch Display Integration (LTDI) chip that helps reduce power consumption.
However, it is also described as more compatible with "traditional" production methods, which might reduce costs while potentially superceding current In-Cell panels. Accordingly, TCL suggests that it might help LCDs stay relevant, as it is prepared to make HVATouch screens for a range of product types and use-cases, in-car screens, monitors and laptops, in the future.
