Surprisingly unknown "LCD display" trend: How to select "Display" that is effective for SOHO/SMEs (1st) (page 1/3)

LCD display that steadily evolves

　I remember that the transition from the CRT display to the liquid crystal display was around 2000, but the support of Windows XP, which appeared right after that, ended on April 9, 2014.Along with the old generation PCs, many of the liquid crystal displays connected to it may have been forced to retire.

　Display videos entered from PCs on the screen -The basic role of the liquid crystal display does not change at all, but evolution is to increase the size of the screen, increase the size, improve image quality, save power, and prevent fatigue.It continues, and the price has dropped remarkably.It looks like a product category that does not change much, and it is a very hot genre.

　In recent years, not only desktop PCs, but also use as external displays of laptop PCs, which tend to be smaller, are increasing, and personal use is also attracting attention.Of course, if you want high color reproducibility in graphics, a high -level external display is essential.

　In this series, we will introduce how to select products mainly based on general applications for SOHO / SMEs from such diversified liquid crystal displays (professional, video production, design, games, and medical care.Do not consider displays specialized in).

　This time, the first one, let's check the trends of the recent LCD displays in places where there is no corporate or individual.

"Wide", "Full HD" "21.5 to 24 type "is the recent top selling

　First, look at the specifications around the screen.As for the screen resolution, the display ratio (4: 3 or 5: 4), which was once the mainstream, has been declining, and now the wide ratio (16: 9 or 16:10) occupies many.ing.

　Not only external displays, but also laptops and tablets displays are increasingly wide -tendency, and the only major products that maintain the square ratio except for specified business use are the only major products, but it is over.There is no situation.

　There is a model with a slightly wider number of heaven and earth ratio in the wide ratio, but on the number, the 16: 9 ratio model as the LCD TV is the mainstream, and it exists in the lineup.In many cases, the price is expensive.Looking at the selling seller rankings announced by the research company, it is said that there is one in the top 10-20th place.

　The screen resolution is 1280 × 720 pixels and 1366 × 768 pixels in low -end tablets and notebook PCs, and is mainly “1920 × 1080 pixels”, which are commonly called “full HD” on the external display handled in this paper.The "2560 x 1440 pixels" called "WQHD" and the "4K" display "3840 x 2160 pixels", which are described later, are also appearing on the higher rank, but the resolution is 1920 x 1080 pixels.no doubt.

　By the way, in the case of 16:10, it will be 1920 x 1200 pixels.The difference is only 120 pixels in the vertical direction compared to the full HD, but the vertical resolution can be maintained from the high -spec high -spec LCD display (1600 × 1200 pixel display) of a year ago, so it can be widened and high resolution.There are a few users who choose 16:10.

　The screen size is 21, mainly 23 type.The volume zone is around 5 to 24 types.Recently, even corporate use is changing to a square type and introducing a wide type is increasing, but if you switch to a product with a wide ratio while maintaining the width, the work area will be smaller, so a 17-19 -inch square type.If you try to switch without discomfort, it will settle to this size in a wide type.

　It is this size that is most powerful in each company's lineup, and A3 (A4 spread: 420 x 297 mm) can be displayed almost in full size (23: 9: 9: 9: 9:It is also suitable for business use in the sense of 16: 9/16: 10).If the width cannot be obtained due to the place where it is placed, or when used as an external display of a laptop, it is one -time compact 21..Type 5 is also a powerful option.

　The type of panel (IPS, VA, TN) that greatly affects the viewing angle, etc., occupies a large weight in selecting a display.From the larger view angle, IPS> VA> TN is in the order of IPS> TN, but it may be directly linked to the price difference, so it is difficult to select IPS for corporate applications to be introduced in multiple units.However, the price of IPS has been reduced in recent years, making it easier to obtain than before.

　The performance of TN panels has improved compared to the past, and when it comes to batch purchases, this is often selected.VA panels have been used mainly on videos / games displays due to the high viewing angle and contrast ratio close to IPS, but the low price of IPS and improvements in performance have progressed, and the number has recently decreased.。

　In addition, the glossy (glare) liquid crystal that has been tashed for a while for video viewing applications is almost out of target for corporate use because of the good black tightening and color development.Because there are many nominations of non -glossy (non -glare), there are many nominations, so manufacturers with product lineup targeting corporations are not glare, and manufacturers limited to individuals are mainly glare in consideration of the appearance at stores.Is quite a few.There is no clause that plays a role in narrowing down the candidates for purchased products.
