Tianma’s OLEDs Looked good and should be here by the end of 2015Tianma was one of only two LCD makers that had meeting rooms on the show floor (the other was Samsung) and had a wide range of displays for mobile devices. The big news is that the company plans to start shipping OLED displays for smartphones and phablets up to 7″ by the end of the year. The first product is a 5.5″ 1280 x 720 resolution OLED that looked very good. Tianma told us that the display uses a delta RGB configuration and sub-pixel rendering to achieve the 400ppi.
Turning to LCDs, there were a number of new IPS panels on display with 5.5″ and 6″ diagonals and Tianma told us that it expects 5.2″ diagonal 2560 x 1600 16:10 displays to be popular with 580 ppi. We looked at a new 5″ “Touch-enabled display” or TED which is an in-cell touch equipped LCD with 1280 x 720 using self inductance. Tianma told us that it has the only single chip in-cell touch solution. Other companies need dual chips.
We next looked at a 1.56″ circular display for wearables and smartwatches. It has 320 x 270 resolution, 500 cd/m² of brightness and has in-cell touch.
Going up in size, the firm will introduce a new 10.1″ 2560 x 1600 panel in May that will be used in a Sony tablet and delivers 299ppi. There was also an 8.9″ 2560 x 1536 display with 288 ppi. Both of these panels have 430 cd/m² of brightness.
Pushing its amorphous silicon technology to its limit, Tianma has an 8.0″ 1920 x 1200 LCD with 223ppi and 900:! contrast. The firm told us that the panel is “low cost” although it wouldn’t be drawn on details.
