What is a "folding smartphone"? What do you want if you fold it? [October 2021]-Fav-Log by ITmedia

　In a word, even "smartphone" sells models (models) with a variety of features. Among them, the one that has attracted much attention recently is the "popular smartphone". What kind of thing is it? And what are the advantages and disadvantages? We will introduce it in combination with the recommended models that can be purchased by October 2021.

　The "Foldable (Foldable)" of Volkswagen smartphones means "folding".

　Recently, organic EL display has gradually become the mainstream in smart phones. compared with LCD, it is not only easy to make the panel thin, but also has the advantage of flexibility. To put it simply, it can easily become a "surface" rather than a plane.

　Let the organic EL display have the advantage of flexibility, so that it can fold the screen, this is the Volkswagen smartphone. As a product sales began in 2019, Royole developed "FlexPai (FlexPai)" is considered to be its forerunner. Since then, Samsung Electronics (Samsung Electronics) have launched "Galaxy Fold", Huawei (Huawei) launched "HUAWEI Mate X", in a sense, the situation can be called "folder double bubble".

　Even after that, new models of Fushuang smartphones have emerged from a number of manufacturers.

　The advantage of folder dual smartphones is that they become compact by folding. The thickness of the fold will come out a little, but keeping the phone in the bag will save space. However, if you open it, the big picture will expand.

　Although it is compact, browsing the website, SNS and watching videos can be enjoyed on the big screen, which is the best benefit.

　As mentioned earlier, folder dual smartphones have a "valley break" and a "mountain break" of the picture, and the recent valley break type with the picture as the inside is the mainstream. If it is a valley break, the picture can be placed on the inside when it is not in use to prevent the picture from being scratched accidentally.

　"if the screen is in it, can't you confirm the notice? "you might think that most of the valley discount models are equipped with sub-displays for confirmation notifications, so you don't have to worry about it.

　The disadvantage of folder dual smartphones is that the most important thing is that there are "creases" on the screen. In the above valley break type model, from the point of view of minimizing the gap when folding, the crease is firm.

　It is also true to slide (trace) this crease with your fingers, and what you will care about anyway. Creases also become apparent when viewing the screen, depending on the viewing angle, the color and brightness of the display.

　However, if a bright image is displayed, creases are unexpectedly ignored. From the oblique point of view, looking at the dark means that it is easy to care if the external light shines strongly on the picture.

　Another weakness of folder smartphones is "foreign objects" such as dust.

　In the Galaxy Fold and HUAWEI Mate X mentioned earlier, in the media-oriented comment stage before the release, there was a problem that the folded hinges entered into large-grained sand, resulting in damage to the picture. Affected by this trouble, the listing of the two terminals was even postponed because of structural improvement.

　With the development of generations, the hinge part has been improved, and the risk of damage caused by foreign body mixing has been gradually reduced. However, there are no dual smartphones that meet the dustproof / dustproof performance specified by IEC (International Electrical Standards Conference). Please pay attention to the use in dusty places and places where sand is flying.

　Introduce the particularly recommended models of folder smartphones that can be purchased in Japan on October 17.
