    Exactly one week has passed since the introduction of the Galaxy Z Fold3 clamshell smartphone; A device that can surely be called the most powerful clamshell smartphone to date. The Galaxy Z Fold3 is the first clamshell smartphone to support an advanced stylus. The presence of the flagship Snapdragon 888 chip and the selfie camera under the display layer are two features of this phone that can rarely be seen simultaneously on a device. But Samsung recently unveiled another manifestation of the device's capabilities with the release of a news release. According to Samsung, the OLED display of this phone consumes less and improves the performance of its internal camera.

    According to Samsung, the OLED display on the Galaxy Z Fold3 is different from other OLED displays. Samsung has called this display Eco OLED, the first part of which should be called "Eco to the power of 2". Apparently, Eco to the power of 2 means that the word Eco here is both abbreviated as economical and stands for ecological. But what is the structure of Samsung's display in the Galaxy Z Fold3 that Samsung has enlarged so much? Takes; Then a layer of polarizer is applied and finally a layer of ultra-thin glass or UTG is drawn on the screen. The task of the middle layer or polarizer is to neutralize any reflection of light. But the problem is that by doing so, a significant portion of the screen light is inevitably blocked and the so-called screen light is blocked. In this way, while adding to the thickness of the screen, the amount of light efficiency is reduced to more than half.

    The interesting thing is that in the display Eco OLED, the middle layer or polarizer has been removed. but how? Apparently, Samsung has slightly changed the original OLED panel and added a new laminate structure. This new structure alone blocks wandering reflections and does the job of a polarizer layer well.

    According to Samsung, the amount of light transmission in the Eco OLED display has increased by 33%, which can reduce energy consumption by up to 25%. We must note that these percentages are large figures and should not be simply ignored. Due to the increased light transmission by the Eco OLED display, more light reaches the selfie camera inside, and this on paper has a positive effect on improving the performance of the camera.

    Samsung's innovations in the Galaxy Z Fold3 display are not limited to its OLED panel. This is apparently the first Samsung smartphone to have a dramatic change in the layout of its display pixels. For nearly a decade, Samsung has been using a unique layout of large rhombic pixels alongside smaller, oval sub-pixels to build its device panel. This arrangement - which is not necessarily found on all Samsung devices - was introduced in 2013 with the launch of the Galaxy S4 with the aim of increasing the maximum pixel density. The layout has not changed significantly since then, and the number of green sub-pixels in it is twice the number of blue and red rhombus pixels. As mentioned, on the Galaxy Z Fold3 display, we seem to see a different arrangement of pixels, with blue and red rhombus pixels being replaced by round pixels. Of course, Samsung has not officially mentioned such a thing, and this is just a point revealed by one of the Twitter activists named IceUniverse. According to IceUniverse, this new layout promises a clearer display (than the Z Fold2 display). Of course, this new arrangement is only related to the deformation of the pixels and has no effect on the pixel density and resolution of the screen.

    As mentioned, the Eco OLED display significantly reduces power consumption and increases battery life. This is the aspect that was referred to as economical at the beginning of the article. But the second aspect, ecological, is related to reducing the use of plastic in the construction of this monitor.

    All of the above is just on paper, and to be sure, you have to wait until August 27 (September 5) - when the Galaxy Z Fold3 launches - to see if the new technology used to build the Eco OLED Does it really make the claimed changes or not? Needless to say, due to the complexity of the production of this display, the cost of the Galaxy Z Fold3 has increased to such an extent that, of course, if it is mass-produced and used in other Samsung devices, this problem will be solved over time.
