===螢幕和輸入方式===
第一和第二代iPad採用1024 x 768像素的觸控式液晶螢幕，尺寸為{{convert|7.75|xx|5.82|in|mm}}，斜角距離為{{convert|9.7|in|mm|sigfig=4}}，並搭配抗指紋與防刮玻璃。[[史蒂夫·賈伯斯]]曾表示7英寸的螢幕「太小以致無法表現軟體」，而10英寸是平板螢幕適合的最小尺寸<ref name="not-7-inch">{{cite news|first=Bianca|last=Bosker|title=Apple's 'iPad 2' Won't Be A Smaller, 7-Inch Version, Steve Jobs Suggests|publisher=The Huffington Post|date=2010-10-19|url=http://www.huffingtonpost.com/2010/10/19/apples-ipad-2-wont-be-a-s_n_767882.html|accessdate=2011-01-07|archiveurl=https://web.archive.org/web/20110204111212/http://www.huffingtonpost.com//2010//10//19//apples-ipad-2-wont-be-a-s_n_767882.html|archivedate=2011-02-04|dead-url=no}}</ref>。與[[iPhone]]相同，iPad設計成可用手指直接控制，而一般的手套或觸控筆將無法在iPad上使用<ref>{{cite news|first=David|last=Pogue|url=http://pogue.blogs.nytimes.com/2007/01/13/ultimate-iphone-faqs-list-part-2/|title=Ultimate iPhone FAQs List, Part 2 – Pogue's Posts Blog&nbsp;– NYTimes.com|publisher=Pogue.blogs.nytimes.com|date=2007-01-13|accessdate=2010-05-31|archiveurl=https://web.archive.org/web/20080512034405/http://pogue.blogs.nytimes.com/2007/01/13/ultimate-iphone-faqs-list-part-2/|archivedate=2008-05-12|dead-url=no}}</ref>，必須使用特別製造的手套或[[电容式感应|电容式]]觸控筆<ref>{{cite web|url=http://www.macworld.com/article/1146421/ipad_accessories.html|title=Expo Notes: iPad cases, touch gloves hot items on expo floor &#124; Tablets &#124; MacUser|publisher=Macworld|accessdate=2010-05-31|archiveurl=https://web.archive.org/web/20121127122848/http://www.macworld.com/article/1146421/ipad_accessories.html|archivedate=2012-11-27|dead-url=no}}</ref><ref>{{cite web|first=Rick|last=Broida|url=http://reviews.cnet.com/8301-19512_7-10443415-233.html|title=Want to take notes on an iPad?

螢幕也會受到其他感應器控制：環境光感應器可自動調整螢幕亮度；一個三軸[[陀螺儀]]會感應iPad的持握方向，並將螢幕調整成水平或垂直顯示。與只能對應顯示三種方向（垂直、右側水平和左側水平）的iPhone（iPhone 6 Plus 除外）或iPod touch內建應用程式不同，iPad的內件應用程式能支援四個方向的螢幕旋轉顯示。因此iPad並沒有「預設」的使用方向，只有主畫面（Home）鍵會因為握持方向而改變相對位置<ref>{{cite web|url=http://www.anandtech.com/show/3640/apples-ipad-the-anandtech-review/4|title=Apple's iPad - The AnandTech Review|first=Anand|last=Lal Shimpi, Brian Klug & Vivek Gowri|publisher=AnandTech|date=2010-04-07|accessdate=2012-08-09|page=4|quote=-{The display rotates smoothly to orient itself properly regardless of how you’re holding it.}-|archiveurl=https://web.archive.org/web/20120823142900/http://www.anandtech.com/show/3640/apples-ipad-the-anandtech-review/4|archivedate=2012-08-23|dead-url=no}}</ref>。

iPad的機身上有四個實體按鍵和開關，包括位在正面靠近螢幕的主畫面鍵，按下後可返回主選單；另有三個實體按鍵和開關在機身側邊：「睡眠/喚醒」和「提高/降低音量」，以及一個在作業系統升級後可改變功能的開關（iPad Air 2沒有此開關）。該開關最初是用在將螢幕鎖定在目前顯示的方向，但在iOS 4.2後，開關的預設功能被改為靜音，而螢幕轉向鎖定的功能則可透過顯示畫面上的虛擬開關控制<ref>{{cite web|url=http://www.macrumors.com/2010/03/12/ipads-mute-switch-replaced-with-screen-rotation-lock/|title=iPad's 'Mute' Switch Replaced With Screen Rotation Lock.|date=2010-03-12|accessdate=2010-03-12|publisher=MacRumors|archiveurl=https://web.archive.org/web/20100315020718/http://www.macrumors.com/2010/03/12/ipads-mute-switch-replaced-with-screen-rotation-lock/|archivedate=2010-03-15|dead-url=no}}</ref>。在隨後與iPad 2同步推出的iOS 4.3更新中，加入可讓使用者自行決定該開關功能的設定項目（螢幕轉向鎖定或靜音）<ref>{{cite news |author1=Eric Slivka |title=iOS 4.3 Beta Brings Software Option for Rotation Lock or Mute on iPad |url=https://www.macrumors.com/2011/01/12/ios-4-3-beta-brings-software-option-for-rotation-lock-or-mute-on-ipad/ |accessdate=2026-01-15 |work=MacRumors |date=2011-01-12}}</ref>。

第一代的iPad並無內建相機鏡頭；iPad 2加入一個機身正面的[[视频图形阵列|VGA]]鏡頭和一個背面的720p鏡頭，兩個鏡頭皆可用作拍攝靜態照片（但僅能拍攝30萬像素的低畫質照片）和錄製30[[幀率|fps]]的影片。後方鏡頭拍攝靜態照片時支援五倍[[數位變焦]]。兩個鏡頭所錄製的影片皆為[[4:3]]比例的全螢幕影片，與iPhone錄製的[[16:9]]寬螢幕影片格式不同<ref>{{cite web|url=http://www.anandtech.com/show/4225/the-ipad-2-review/8|title=The Apple iPad 2 Review|first1=Brian|last1=Klug|first2=Anand Lal|last2=Shimpi|first3=Vivek|last3=Gowri|date=2011-03-19|accessdate=2012-07-29|quote=-{Tapping on the preview exposes for the tapped region, but since the rear camera is fixed focus, focus doesn’t change.}-|publisher=AnandTech|archiveurl=https://web.archive.org/web/20120505073541/http://www.anandtech.com/show/4225/the-ipad-2-review/8|archivedate=2012-05-05|dead-url=no}}</ref>。iPad不支援觸控變焦，但可改變自動曝光的偵測點。前後的相機皆可在FaceTime中使用，可讓iPad播打視訊電話至iPhone、iPod touch和運行[[Mac OS X Snow Leopard|Snow Leopard]]以上版本之作業系統的麥金塔電腦<ref>{{cite news|url=http://money.cnn.com/2011/03/02/technology/ipad_2_announcement/|title=IPad 2: Thinner, faster, and with a Steve Jobs surprise|first=David|last=Goldman|publisher=CNNMoney|date=2011-03-02|accessdate=2011-03-02|archiveurl=https://web.archive.org/web/20110304152544/http://money.cnn.com/2011/03/02/technology/ipad_2_announcement/|archivedate=2011-03-04|dead-url=no}}</ref>。
