Description
本發明係關於一種近眼顯示裝置,尤其是一種降低紗窗效應的近眼顯示裝置。The present invention relates to a near-eye display device, in particular to a near-eye display device that reduces the screen door effect.
顯示裝置一般常以視覺上是否能看到畫素點來評估顯示清晰度。當畫素密度不足時,視覺上會看到畫素之間出現分割線情況,就如同在紗窗後面看東西,而稱為「紗窗效應(screen-door effect)」。一般而言,當顯示裝置與使用者之間的觀看距離越大,使用者在固定視場角所能看到的畫素數目就越多,使得紗窗效應較不鮮明。然而,在例如虛擬實境等近眼顯示裝置的應用中,顯示裝置幾乎是緊貼使用者的眼睛設置,使得觀看距離僅剩數公分,造成在固定視場角所能看到的畫素數目就顯著減少,而凸顯出「紗窗效應」的問題。Display devices generally evaluate display clarity based on whether pixels can be visually seen. When the pixel density is insufficient, you will visually see dividing lines between pixels, just like looking at things behind a screen window, which is called the "screen-door effect". Generally speaking, when the viewing distance between the display device and the user is larger, the number of pixels that the user can see at a fixed viewing angle is greater, making the screen door effect less distinct. However, in applications such as near-eye display devices such as virtual reality, the display device is placed almost close to the user's eyes, so that the viewing distance is only a few centimeters, resulting in the number of pixels that can be seen at a fixed viewing angle. Significantly reduced, highlighting the problem of "screen door effect".
習知改善紗窗效應的技術係形成較小的畫素以提升單位面積的畫素數目。然而,較小的畫素必須配合較高精度的製程技術,例如高精度的微影製程,使得製程困難度較高、良率不易控制,且設備要求也相對較高,製造成本也隨之遽增。A conventional technique for improving the screen door effect is to form smaller pixels to increase the number of pixels per unit area. However, smaller pixels must be equipped with higher-precision process technology, such as high-precision lithography process, which makes the process more difficult, the yield is difficult to control, and the equipment requirements are relatively high, and the manufacturing cost has also increased rapidly. increase.

具體而言,顯示面板100包含配置成陣列形式的複數畫素單元(例如101A、101B、101C)。各畫素單元較佳包含可構成彩色影像的多顏色畫素。舉例而言,各畫素單元包含例如紅色(R)、綠色(G)及藍色(B)三個畫素,但不以此為限。依據實際應用,於其他實施例,各畫素單元可包含紅色(R)、綠色(G)、藍色(B)及白色(W)四個畫素。各畫素110具有濾光器或發光層,以提供預定顏色的光。阻光區域120(例如黑色矩陣阻劑)設置在相鄰畫素110之間,以避免相鄰畫素110之間發生混光。換言之,相鄰畫素110之間具有畫素間距(即阻光區域120的寬度),以分隔相鄰畫素110。舉例而言, 如圖1所示,三個畫素單元101A、101B、101C沿Y軸方向設置,且各畫素單元的紅色(R)、綠色(G)及藍色(B)的三個畫素110沿X軸設置。在Y軸方向上,相鄰的畫素110之間具有畫素間距WY,且在X軸方向上,相鄰的畫素110之間具有畫素間距WX。在此須注意,畫素單元的數目、各畫素單元的畫素數目及其配置方式,可依據實際應用而改變,不以實施例所示為限。Specifically, the
震動元件200X較佳為可藉由電訊號驅動的震動器,例如電磁震動器或壓電震動器,但不以此為限。於一實施例,震動元件200X較佳為具有震動幅度為100μm以下且振動頻率為60Hz以上的任何合宜的震動器。於另一實施例,震動元件200X較佳為具有震動幅度為50μm以下,或甚至10μm以下,且振動頻率為120Hz以上的任何合宜的震動器。震動元件200X較佳設置於顯示面板100的側邊。舉例而言,震動元件200X可設置於顯示面板100的側邊中間或角落。換言之,震動元件200X較佳設置於顯示面板100的周邊位置。再者,震動元件200X可藉由任何合宜的機制連接顯示面板100,以帶動顯示面板100震動。舉例而言,震動元件200X可藉由夾具、黏著、鎖附等方式連接顯示面板100,以使得震動元件200X震動時,可帶動顯示面板100震動。如圖1所示,於此實施例,至少一個震動元件200X設置於顯示面板100平行Y軸方向的側邊,以帶動顯示面板100沿X軸方向震動,但不以此為限。依據顯示面板100的尺寸及所使用的震動元件200X,複數個震動元件200X可成對設置於顯示面板100的相對兩側,以帶動顯示面板100朝相對兩側往復震動。再者,震動元件200X的震動幅度較佳依據實際應用決定,例如依據畫素間距,於後詳述。The
參考圖2說明本發明之近眼顯示裝置的操作,其中圖2為本發明一實施例之近眼顯示裝置之操作示意圖。如圖2所示,兩個震動元件200X沿X軸方向設置於顯示面板100的相對兩側。當震動元件200X沿X軸方向震動時,帶動顯示面板100沿X軸方向震動,使得複數畫素110沿X軸方向發生往復位移。於一實施例,複數畫素110的位移距離DX較佳小於或等於畫素間距WX(即DX≦WX),以降低畫素110間混光的可能性。再者,於另一實施例,複數畫素110的位移距離DX較佳等於或大於畫素間距WX的1/2(即1/2WX≦DX),使得複數畫素110位移以有效涵蓋阻光區域120的原本位置。舉例而言,以解析度386-615 ppi (pixels per inch)的顯示面板而言,畫素節距(pixel pitch)約為40-60 μm,且影像的更新率約為60-120Hz。以開口率為10%-90%計算,畫素間距的範圍約為4-56μm。因此,震動元件200X較佳能帶動顯示面板100以60Hz以上或更佳為120Hz以上的頻率震動,而使得畫素110在X方向往復位移,且位移距離較佳約4-56μm或以下。藉此,在視覺上,相當於使得畫素110在X軸方向的顯示範圍朝阻光區域120外擴實質約畫素間距WX的大小,進而降低影像於X軸方向的紗窗效應。The operation of the near-eye display device of the present invention will be described with reference to FIG. 2 , which is a schematic diagram of the operation of the near-eye display device according to an embodiment of the present invention.

圖5為本發明另一實施例之近眼顯示裝置之示意圖。如圖5所示,本發明之近眼顯示裝置可更包含控制元件300,其中控制元件300控制震動元件(例如200X及/或200Y)的震動。控制元件300可為電連接震動元件(200X及/或200Y)的驅動器,以提供驅動訊號至震動元件(200X及/或200Y),進而控制震動元件(200X及/或200Y)的震動幅度或振動頻率。於一實施例,控制元件300可與近眼顯示裝置的其他電性元件(例如電路板)整合或獨立設置。FIG. 5 is a schematic diagram of a near-eye display device according to another embodiment of the present invention. As shown in FIG. 5 , the near-eye display device of the present invention may further include a
再者,本發明的近眼顯示裝置可更包含透鏡400,其中透鏡400設置於顯示面板100及使用者20之間。透鏡400用以放大顯示面板100形成的影像,並將放大的影像朝使用者的眼睛折射。透鏡400可用以增加使用者可觀看的視角,並用以調整焦距。藉此,可使得使用者有著觀看的影像較顯示面板100實際顯示的影像還大的效果。Furthermore, the near-eye display device of the present invention may further include a
此外,本發明的近眼顯示裝置可更包含殼體500,其中殼體500提供容置空間510,以供容置近眼顯示裝置的元件,例如顯示面板100、震動元件200X、200Y、控制元件300、透鏡400等。依據實際應用,殼體500可具有各種合宜的形式。舉例而言,殼體500可具有使用者可穿戴的形式,例如鏡架形式或頭盔形式,使得近眼顯示裝置可固定於使用者的頭部,但不以此為限。於其他實施例,殼體500可具有其他形式,使得使用者可手持近眼顯示裝置靠近眼睛。此外,殼體500可設計有固定機構來定位顯示面板100及震動元件200X、200Y的相對位置,以達到震動元件200X、200Y帶動顯示面板100的震動。再者,殼體500亦可設置有減震元件,例如吸震棉,以減少震動元件對於近眼顯示裝置整體的振動影響,使得在藉由震動元件帶動顯示面板震動而降低紗窗效應時,使用者實質感受不到近眼顯示裝置在震動。In addition, the near-eye display device of the present invention may further include a
在此須注意,本發明之近眼顯示裝置較佳應用於虛擬實境顯示,且依據實際應用可包含一個顯示面板或兩個顯示面板。當使用兩個顯示面板時,各顯示面板較佳具有對應的震動元件,但不以此為限。再者,本發明之近眼顯示裝置以震動元件沿X軸或Y軸方向為例說明,但於其他實施例,震動元件可設置於顯示面板的角落,以帶動顯示面板斜向震動,而使得震動方向與X軸或Y軸方向之間具有小於90度的夾角。It should be noted here that the near-eye display device of the present invention is preferably used for virtual reality display, and may include one display panel or two display panels depending on the actual application. When two display panels are used, each display panel preferably has a corresponding vibration element, but is not limited to this. Furthermore, the near-eye display device of the present invention takes the vibrating element along the X-axis or Y-axis direction as an example. However, in other embodiments, the vibrating element can be disposed at the corner of the display panel to drive the display panel to vibrate obliquely, causing the vibration to occur. The angle between the direction and the X-axis or Y-axis direction is less than 90 degrees.
本發明之近眼顯示裝置藉由震動元件帶動顯示面板震動,而使得畫素往復位移產生微幅震動的效果;尤其是本發明之近眼顯示裝置將震動元件的震動幅度控制在使得畫素的位移產生暈開填充畫素間的阻光區域的效果,而不會影響相鄰畫素的品質(例如不會混光產生色偏)。再者,本發明之近眼顯示裝置藉由震動元件震動而產生的影像震動具有類似高頻的簡諧運動,當應用於虛擬實境顯示時,視覺所見與前庭系統大致相同,觀賞時不致發生虛擬實境暈動症。The near-eye display device of the present invention uses the vibration element to drive the display panel to vibrate, so that the reciprocating displacement of the pixels produces a slight vibration effect; in particular, the near-eye display device of the present invention controls the vibration amplitude of the vibration element to cause the displacement of the pixels to occur Blur the effect of filling the light-blocking area between pixels without affecting the quality of adjacent pixels (for example, without mixing light to produce color casts). Furthermore, the image vibration generated by the vibration of the vibrating element of the near-eye display device of the present invention has similar high-frequency simple harmonic motion. When applied to virtual reality display, the visual experience is roughly the same as that of the vestibular system, and virtual vibration will not occur during viewing. Reality motion sickness.
