OLED屏能否助三星挽回頹勢(shì),?

OLED屏能否助三星挽回頹勢(shì),?

Kevin Purdy 2014年11月18日
由于旗下多款智能手機(jī)和平板電腦使用OLED顯示屏,,韓國(guó)三星集團(tuán)無(wú)疑是這種技術(shù)的霸主。但問(wèn)題來(lái)了,,OLED超艷麗的色彩對(duì)三星設(shè)備的銷路究竟有益還是有害,?

????然而在現(xiàn)實(shí)中,許多行業(yè)權(quán)威反饋的情況卻恰恰相反,??萍忌罹W(wǎng)站The Verge的編輯迪特爾?波恩表示,Galaxy Tab S的顯示屏顏色“在我看來(lái)仍然有過(guò)于飽和的傾向”,,不過(guò)他補(bǔ)充道:“但和前幾年相比,,三星還是顯著改善了失真的情況?!庇布W(wǎng)站Anandtech在一篇對(duì)Galaxy S5總體還算比較正面的評(píng)測(cè)中指出,,這部手機(jī)在“色彩平衡上還存在稍微偏綠的小問(wèn)題”。實(shí)際上,,用戶似乎也認(rèn)同AMOLED顯示屏的顏色要更加生動(dòng),。至于這些顏色在實(shí)際生活中怎么樣,是否還像顯示屏里那樣自然或飽滿,,那就是另一回事了,。

????三星可能對(duì)色彩飽和度問(wèn)題很敏感,因?yàn)橐晃恢饕?jìng)爭(zhēng)對(duì)手曾經(jīng)公開抨擊過(guò)這個(gè)問(wèn)題,。蘋果公司CEO蒂姆?庫(kù)克曾于2013年2月在高盛(Goldman Sachs)投資人大會(huì)上指出,,OLED屏幕的“顏色飽和度太糟糕了”。他還稱:“如果你想在網(wǎng)上買東西,,而且你想知道它是什么顏色……在你根據(jù)OLED屏幕上的顏色做決定前,,最好再慎重考慮一遍?!?/p>

????AMOLED之所以會(huì)被揪住這根辮子,,部分原因恰恰和它一個(gè)看似優(yōu)勢(shì)的因素有關(guān)。AMOLED技術(shù)的色域比其它顯示技術(shù)更寬,。目前大多圖像的顏色還限制在已經(jīng)有18年歷史的RGB標(biāo)準(zhǔn)里,,但是AMOLED在技術(shù)上可以遠(yuǎn)遠(yuǎn)超越這個(gè)色域,而且三星也經(jīng)常允許它“超綱發(fā)揮”,。三星的有些設(shè)備提供了顏色校正模式,。但大多數(shù)情況下,三星允許顯示屏的顏色更加醒目和飽滿,,尤其是在可見光譜的紅色部分,。

????在評(píng)測(cè)完Galaxy S5手機(jī)后,視頻設(shè)備評(píng)測(cè)師埃里卡?格里芬表示:“這些顏色在我看來(lái)很不舒服,但是你喜不喜歡這種效果則取決于你自己,。我明白三星在追求一種吸引眼球的效果,,以吸引人們的注意力……對(duì)于有些人,它看起來(lái)是挺漂亮的,,但在另一些人看來(lái)卻覺(jué)得很難受,。”

????此外,,在你使用設(shè)備的過(guò)程中,,這種色彩的感覺(jué)可能還會(huì)有所變化。OLED顯示屏用來(lái)發(fā)藍(lán)色光的有機(jī)材料衰減得很快,,遠(yuǎn)遠(yuǎn)超過(guò)紅色或綠色,。一旦它開始衰減,總體的顏色平衡就會(huì)產(chǎn)生變化,。三星和其它設(shè)備廠商也想了一些辦法解決這個(gè)問(wèn)題,,比如把藍(lán)色像素的尺寸增加一倍,但目前這個(gè)問(wèn)題仍然沒(méi)有徹底解決,。

????一位三星發(fā)言人表示,,三星最新推出的Quad-HD Super AMOLED屏幕具有“沉浸式觀賞體驗(yàn)、很高的對(duì)比度,,而且有比競(jìng)爭(zhēng)對(duì)手更廣的色域”,。前文提到的Galaxy Tab S平板電腦內(nèi)置了一塊用于穩(wěn)定顏色的專用芯片??萍季W(wǎng)站Anandtech表示,,在最基本的設(shè)置上,它基本達(dá)到了預(yù)期效果,。

????顯示屏的顏色顯示對(duì)于移動(dòng)設(shè)備是非常重要的,,尤其是它必須要滿足用戶的預(yù)期。我們都知道Twitter的Logo是天藍(lán)色的,,如果用戶和營(yíng)銷人員發(fā)現(xiàn)自己手上的設(shè)備顯示的Logo帶點(diǎn)綠色,,非抓狂不可。LCD顯示屏當(dāng)然也并非毫無(wú)進(jìn)步,,如今的LCD屏幕也變得更薄,、更明亮,分辨率也變得更高,。不過(guò)IHS公司的賈克漢瓦指出,消費(fèi)者選擇一款移動(dòng)設(shè)備時(shí),,看重的并不只是色彩,、電池壽命或厚度。

????她表示:“這個(gè)行業(yè)的勝者不僅要有很好的顯示技術(shù),,還要有很好的總體性能,。沒(méi)有人真的會(huì)因?yàn)椤矣玫氖亲盍恋钠桨咫娔X’或者‘我的顏色更真實(shí)’而感覺(jué)良好,。最終造就一款顯示屏和設(shè)備的,是一系列功能的組合,?!边@可能解釋了為什么三星及其AMOLED研究團(tuán)隊(duì)還需要更多時(shí)間來(lái)解決屏幕發(fā)紅問(wèn)題。(財(cái)富中文網(wǎng))

????In reality, this is the opposite of what many industry pundits claim. The colors displayed on Samsung’s Galaxy Tab S, according to Dieter Bohn, an editor for the tech-lifestyle website The Verge, “still tend to look over-saturated to my eyes,” though he added that “Samsung has toned things down considerably from years past.” In an otherwise positive review of a newer Galaxy S5 smartphone model, Anandtech, a computer hardware site, made note of “minor issues with excessive green in the color balance.” In essence, people seem to agree that the colors of AMOLED displays are more vivid. Whether or not those colors are natural or accurate based on what the eye would see in real life is another matter entirely.

????Samsung may be sensitive to accusations of color problems because one of its main rivals is on record about it. Apple CEO Tim Cook told a Goldman Sachs investors’ conference in February 2013 that “the color saturation is awful” on OLED displays. He added: “If you ever buy anything online and you want to really know what the color is . . . you should really think twice before you depend on the color of the OLED display.”

????Part of the issue has to do with a seeming strength of AMOLED technology. It can create a wider range of colors than other display technologies. While the colors of most images are limited to fit inside the 18-year-old sRGB color gamut, AMOLED screens can technically reach far beyond that range, and Samsung often lets them. Some Samsung devices offer a display-correcting “mode”— “Professional Photo” is one—but for the most part, Samsung allows colors to run bolder and more saturated, especially in the red part of the visible spectrum.

????“The colors look really off to me, but it’s up to you whether you like this effect or not,” says Erica Griffin, an in-depth video device reviewer, in her take on Samsung’s Galaxy S5. “I know Samsung is heading for an effect that’s eye-catching, to get people’s attention . . . For some people, that looks pretty, and for others it’s just an eyesore.”

????It’s also a look that may change as you use your device. The organic materials used to make blues in OLED displays wear out far more quickly than the reds or greens. As they start to wear out, the overall balance of color shifts. Samsung and other device makers often try to correct for this—for example, by making blue sub-pixels twice as large—but it remains an unsolved issue.

????A Samsung spokesperson pointed to the company’s latest displays, dubbed Quad-HD Super AMOLED, as having “an immersive viewing experience with a high contrast ratio and a wider color range” than the competition. The Galaxy Tab S featured in the aforementioned ad has a dedicated chip in it that can stabilize colors. At its most basic setting, tech site Anandtech says it mostly has the desired effect.

????Colors are important on mobile devices for one overarching reason: managed expectations. Knowing that Twitter uses a sky blue color for its logo, it can be jarring for users and marketers alike to see a version with a tinge of green. LCD display technology certainly is not standing still—displays are becoming thinner, brighter, and even more high-definition. But IHS’s Jakhanwal notes that it is more than just colors, battery life, or thinness that gets a device into buyers’ hands.

????“The winners are going to be the device that has not just superior display technology, but superior overall performance,” she says. “Nobody is really going to feel good that, ‘Now I have the brightest tablet,’ or ‘Now my colors are more real.’ It’s a combination of features that make the display and the device.” Which may be good reason for Samsung and its market-moving AMOLED research teams more time to move its displays out of the red.
