Do you know that good old song from group Mike and the Mechanics, beginning with words „Every generation, blames the one before..."?
Usually it´s true in life, but in technics it is always true. Newer components are almost always better than older ones and in case of „gen4“ displays it brings several improvements. It´s worth of mentioning that the core of displays including the graphic processor ( Diablo 16 or Picaso) remains unchanged, that´s why also a compatibility with older displays and with a powerful graphic software Workshop 4.
What´s new / changed?
• thinner design, modules are thinner and also thanks to a lack of pin header they require substantially less space from a bottom side
• pin header for power supply and programming is replaced by an FFC connector, which also contains many other processor pins. Each display is supplied with a 15 cm FFC cable and with a small PCB - „IB – interface board“, serving to interconnect programming cable with an FFC cable and the display
• extra high brightness displays. In the gen4, also the types with an „SB“ suffix can be found (super bright, 800-1000 nit) with more than a double brightness in comparison to common types. That´s why they are also suitable for exterior and on places with strong ambient lighting
• integrated design cover lens bezel. Displays with a „CLB“ suffix (cover lens bezel) have at production integrated glass bezel as we know it for example from tablets. Such a display is also easy to integrate into an end device. Bottom of the bezel also features a thin double-sided sticking tape.
• 5“ display. A new 5” display was added into the gen4 family (800x480 px)
• mechanical support for mounting of a PCB with your application. This way a “combo” arises, which is mechanically stable and compact. For this case also short 30 mm FFC cables will be available.
Good news is also that the gen4 doesn´t replace a previous generation and both versions will be produced simultaneously. That´s why those of you, who have everything “tuned” on a previous version and above mentioned advantages are not important for us, there´s no need to change anything pr to worry about possible redesign.
The last benefit of a new series is a feelingly lower price, i.e. a module of the same size and of same features (for example with a capacitive touch panel) is in a new series feelingly cheaper (roughly -15 -35%, depending on a type). This might be eventually the one and only but strong reason to migrate from older to a new series.
Selected types of gen4 are already in our stock. Upon request we´re able to supply you any other types in a short lead-time and at favourable conditions.
