[0002] 可視角度係指用戶可以從不同方向清晰地觀察螢幕上所 有内容之角度，係LCD顯示屏非常重要之參數。可視角度 之產生是由於提供LCD顯示屏之光源經螢幕折射和反射後 ，輸出方向發生了變化，並產生了一定角度，在超出這 一角度觀看時就會產生色彩失真現象。比如：你坐在LCD 前左右兩邊70度都可以清晰看到圖像，那麼這個顯示屏 水準可視角度就為140度，垂直之可視角度是同樣道理， 然而，當你超過這個角度看顯示屏時就會看不清楚或所 看到之影像顏色不正常。 [0003] 對於先前之LCD顯示屏，幾乎都存在可視角度問題，當超 過可視角度觀看顯示屏圖像時，為了使圖像更清晰，使 用者必須手動去調整LCD顯示屏上下或左右之角度，以達 到最佳之觀看效果，極不方便。 【發明内容】 [0004] 有鑒於此，有必要提供一種顯示方向自動調整之顯示裝 置及其方法。 [0005] —種顯示方向自動調整之顯示裝置，其包括一顯示屏、 一轉動機構以及一固定架。所述顯示屏通過所述轉動機 構與所述固定架連接，其具有一最佳可視角度。所述轉 動機構用於使所述顯示屏相對於固定架轉動。所述顯示 097101128 表單編號A0101 第4頁/共15頁 1003256785-0 1358013 .100—年.07月15日修正_頁 裝置還包括一自動調整系統，所述自動調整系統包括： [0006] 影像獲取單元，用於獲取顯示屏前之場景影像資料； ' [0007] 偵測軍元，用於偵測場景影像資料中人眼所在位置； [0008] 分析單元，用於根據所述人眼位置及顯示屏之最佳可視 角度得到顯示屏需要調整之角度； [0009] • 轉動控制單元，用於根據所述分析單元得到之顯示屏需 要調整之角度驅動所述轉動機構調整顯示屏方向，使得 人眼位於顯示屏之最佳可視角度内。 [0010] 一種顯示方向自動調整之方法，用於調整一具有最佳可 視角度之顯示屏之顯示方向，其包括以下步驟： [0011] 獲取顯示屏前之場景影像資料； [0012] 偵測場景影像資料中之人眼位置； [0013] 根據所述人眼位置及顯示屏之最佳可視角度得到顯示屏 需要調整之角度； ^ [0014] 根據所述顯示屏需要調整之角度調整顯示方向，使人眼 位於顯示屏最佳可視角度内。 [0015] 本發明通過攝取顯示屏前影像資料，然後偵測人眼位置 ，並根據人眼位置及顯示屏之最佳可視角度調整顯示屏 顯示方向，達到顯示方向自動調整之效果，可使顯示裝 置更加便於使用。 [0016] 【實施方式】 下面將結合附圖對本發明作一具體介紹。 097101128 表單編號A0101 第5頁/共15頁 1003256785-0 1358013 [0017] ，ί〇0年07月15日修正替k頁 如圖1和圖2所示，本發明之顯示方向自動調整之顯示裝 置1包括一顯示屏100、一轉動機構200以及一固定架500 °所述顯示屏100通過所述轉動機構200與所述固定架= 500連接。 [0018] 所述顯示屏1〇〇具體可為LCD顯示屏。其具有一最佳可視 角度，用戶在該角度範圍内均可清晰地觀察顯示屏1〇〇上 所顯示之内容，具體如正對顯示屏100之角度。 [0019] [0020] 所述轉動機構200用於控制顯示屏100相對於所述固定架 500轉動，其包括一馬達210以及一轉動架220。所述馬 達210用於驅動轉動架220轉動，所述轉動架220與所述 顯示屏100固定連接。所述轉動架220具體可以為雙轴架 或者四點支撐架》所述轉動機構200可限定顯示屏1〇〇在 水平方向180度或垂直方向90度範圍内旋轉。 如圖3所示，本發明之顯示方向自動調整之顯示裝置1還 包括一自動調整系統300。所述自動調整系統300包括： 影像獲取單元31〇，偵測單元320，分析單元330以及轉 動控制單元34{)。[0002] The viewing angle refers to the angle at which the user can clearly observe all the content on the screen from different directions, which is a very important parameter of the LCD display. The viewing angle is generated by the fact that the source of the LCD display is refracted and reflected by the screen, the output direction changes, and an angle is generated, which causes color distortion when viewed beyond this angle. For example, if you sit at 70 degrees on the left and right sides of the LCD, you can see the image clearly. The viewing angle of this display is 140 degrees. The vertical viewing angle is the same. However, when you look at the display beyond this angle, It will not be clear or the color of the image you are seeing is not normal. [0003] For the previous LCD display screen, almost all of the viewing angle problems exist. When viewing the display screen image beyond the viewing angle, in order to make the image clearer, the user must manually adjust the angle of the LCD display up and down or left and right. In order to achieve the best viewing effect, it is extremely inconvenient. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide a display device that automatically adjusts the display direction and a method thereof. [0005] A display device for automatically adjusting the display direction, comprising a display screen, a rotating mechanism and a fixing frame.
