Two distances D3. 099137553 Form nickname A0101 Page 11/Total 21 page 0992065434-0 201220843 [0043] The difference value between the first distance, the second distance and the third distance is calculated by a microprocessor 170, and according to the difference value A control signal is generated to drive an angle adjustment device 160 by which the display 110 is rotated to a position facing the infrared receiving device 120. [0044] Preferably, the first infrared ray emitting device 130, a second infrared ray emitting device 140, and a third infrared ray emitting device 150 are located at three vertices of an equilateral triangle. Further, the angle adjusting means 160 rotates the display 110 to a position where the distance between the infrared receiving device 120 and the first infrared emitting device 130, the second infrared emitting device 140, and the third infrared emitting device 150 is equal. The distance % is calculated by the following formula: d / two (
Dj + Dj + Dj) /3，其中Di、D2、D3分別代表第一距離、 第二距離與第三距離。 [0045] 優選地，該第一、第二及第三紅外線發射裝置130、140 、150發射第一、第二及第三紅外線信號的時機可藉由設 置於紅外線接收設備120上的開關裝置122所控制。用戶 按下開關裝置122的按鈕，即可實現對顯示裝置100顯示 角度的自動調整。 [0046] 可以理解地，該紅外線發射裝置並不限於三個，其也可 以是兩個或者三個以上。其可以安裝於顯示器的任何位 置，只要能實現檢測該多個紅外線發射裝置與紅外線接 收設備之間的距離的差值，並將顯示器調整用戶適於觀 看的角度即可。 [0047] 综上所述，本發明符合發明專利要件，爰依法提出專利 申請。惟，以上所述者僅為本發明之較佳實施例，舉凡 099137553 表單編號A0101 第12頁/共21頁 0992065434-0 201220843 熟悉本案技藝之人士，在爰依本發明精神所作之等效修 飾或變化，皆應涵蓋於以下之申請專利範圍内。 【圖式簡單說明】 [0048] 圖1係本發明實施例的顯示裝置的功能模組圖。 [0049] 圖2係本發明實施例的顯示裝置的結構示意圖。 [0050] 圖3係本發明實施例的紅外線接收設備的結構示意圖。 [0051] 圖4係本發明實施例的角度調整裝置的結構示意圖。 【主要元件符號說明】Dj + Dj + Dj) /3, where Di, D2, D3 represent the first distance, the second distance and the third distance, respectively. [0045] Preferably, the timings of the first, second, and third infrared emitting devices 130, 140, and 150 emitting the first, second, and third infrared signals may be provided by the switching device 122 disposed on the infrared receiving device 120. Controlled. The user can press the button of the switch device 122 to automatically adjust the display angle of the display device 100. [0046] It is to be understood that the infrared ray emitting device is not limited to three, and it may be two or more. It can be mounted at any position on the display as long as it is possible to detect the difference in distance between the plurality of infrared emitting devices and the infrared receiving device, and adjust the display to an angle suitable for viewing by the user. [0047] In summary, the present invention complies with the requirements of the invention patent, and submits a patent application according to law.
