Description

矽基液晶面板及投影設備Silicon-based liquid crystal panel and projection equipment

本發明是有關於一種矽基液晶面板及投影設備，且特別是有關於一種具有子像素抖動的LCoS面板和一種包含LCoS面板的投影設備。The present invention relates to a silicon-based liquid crystal panel and projection equipment, and in particular to an LCoS panel with sub-pixel dithering and a projection equipment including the LCoS panel.

LCoS是使用位在矽底板（backplane）頂部的液晶層的小型化反射性主動矩陣液晶顯示器或微型顯示器。其亦稱為空間光調製器。LCoS初始開發用於投影電視但現用於波長選擇開關、結構化照明、近眼顯示器以及光學脈衝塑形。LCoS顯示器的尺寸與像素大小高度相關。為了獲得微小的顯示模組，縮小像素的大小是唯一的方式。一些投影機供應商提出可將顯示屏幕移位一半像素距離以增加影像解析度的電子移位（e-shift）裝置。其稱做光學抖動（wobulation）。然而，電子移位裝置對於擴增實境（argument reality；AR）的應用來說體積太大。LCoS is a miniaturized reflective active-matrix liquid crystal display or microdisplay that uses a liquid crystal layer on top of a silicon backplane. It is also known as a spatial light modulator. LCoS was originally developed for projection television but is now used in wavelength selective switches, structured lighting, near-eye displays, and optical pulse shaping. The size of an LCoS display is highly related to the pixel size. In order to get tiny display modules, shrinking the size of the pixels is the only way. Some projector suppliers propose electronic shift (e-shift) devices that can shift the display screen by half a pixel distance to increase image resolution. It is called optical jitter (wobulation). However, the electronic displacement device is too bulky for augmented reality (argument reality; AR) applications.

本發明提供一種具有子像素抖動的LCoS面板和一種包含LCoS面板的投影設備。包含LCoS面板的投影設備的體積小，且投影設備可提供高影像解析度。The present invention provides an LCoS panel with sub-pixel dithering and a projection device including the LCoS panel.

為讓本發明的上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail together with the accompanying drawings.

圖1示出根據本發明的實施例的投影設備的示意圖。參考圖1，本實施例的投影設備100包含光源110、矽基液晶（LCoS）面板120、光束分光器裝置130以及投影透鏡裝置140。投影設備100將第一抖動影像210和第二抖動影像220投影到物件（圖1中未示出）以形成具有高解析度的投影影像200。物件可以是螢幕或人眼，但本發明不限於此。Fig. 1 shows a schematic diagram of a projection device according to an embodiment of the present invention. Referring to FIG. 1 , the projection device 100 of this embodiment includes a light source 110 , a liquid crystal on silicon (LCoS) panel 120 , a beam splitter device 130 and a projection lens device 140 . The projection device 100 projects the first shaking image 210 and the second shaking image 220 onto an object (not shown in FIG. 1 ) to form a projected image 200 with high resolution. The object can be a screen or a human eye, but the invention is not limited thereto.

具體來說，光源110配置成將照明光束I1輸出到光束分光器裝置130。光束分光器裝置130配置成接收照明光束I1且將具有第一偏振的照明光束I1反射到LCoS面板120。LCoS面板120配置成將照明光束I1轉換成影像光束I2且將影像光束I2輸出到光束分光器裝置130。Specifically, the light source 110 is configured to output the illumination beam I1 to the beam splitter device 130 . The beam splitter device 130 is configured to receive the illumination beam I1 and reflect the illumination beam I1 having the first polarization to the LCoS panel 120 . The LCoS panel 120 is configured to convert the illumination beam I1 into an image beam I2 and output the image beam I2 to the beam splitter device 130 .

光束分光器裝置130將具有第二偏振的影像光束I2傳輸到投影透鏡裝置140。換句話說，光束分光器裝置130可控制影像光束I2的光偏振且將偏振影像光束I2輸出到投影透鏡裝置140。在本實施例中，光束分光器裝置130可以是用於反射第一偏振且傳輸第二偏振的偏振分光鏡（polarizing beamsplitter；PBS）。舉例來說，光束分光器裝置130反射具有S偏振的光束且傳輸具有P偏振的光束，但本發明不限於此。The beam splitter device 130 transmits the image beam I2 with the second polarization to the projection lens device 140 . In other words, the beam splitter device 130 can control the light polarization of the image beam I2 and output the polarized image beam I2 to the projection lens device 140 . In this embodiment, the beam splitter device 130 may be a polarizing beam splitter (polarizing beamsplitter; PBS) for reflecting the first polarization and transmitting the second polarization. For example, the beam splitter device 130 reflects the beam with S polarization and transmits the beam with P polarization, but the invention is not limited thereto.

投影透鏡裝置140配置成輸出偏振影像光束I2以形成投影影像200。在一實施例中，投影透鏡裝置140可包含准直器和/或一或多個透鏡群組以處理和傳輸影像光束I2。影像光束I2包含第一抖動影像210和第二抖動影像220的顯示內容。因此，第一抖動影像210和第二抖動影像220投影到物件以形成投影影像200。The projection lens device 140 is configured to output a polarized image beam I2 to form a projected image 200 . In one embodiment, the projection lens device 140 may include a collimator and/or one or more lens groups to process and transmit the image beam I2. The image beam I2 includes display contents of the first shaking image 210 and the second shaking image 220 . Therefore, the first shaking image 210 and the second shaking image 220 are projected onto the object to form the projected image 200 .

此外，LCoS面板120包含多個像素。舉例來說，圖1中示出兩個像素124_1和像素124_2，且像素124_1和像素124_2中的每一個包含四個子像素。兩個像素124_1和像素124_2繪示顯示影像實際上在LCoS面板120內移位一半像素。In addition, the LCoS panel 120 includes a plurality of pixels. For example, two pixels 124_1 and 124_2 are shown in FIG. 1 , and each of the pixels 124_1 and 124_2 includes four sub-pixels. Two pixels 124_1 and 124_2 show that the display image is actually shifted by half a pixel in the LCoS panel 120 .

在本實施例中，LCoS面板120依序顯示第一抖動影像210和第二抖動影像220。每一抖動影像可繪示不同彩色影像。由於存在三個基本顏色（例如紅色、綠色以及藍色）、兩個抖動影像以及兩個極性幀，故顯示週期（cycle）包含12個幀。產生無閃爍和平滑的顯示影像需要大於30個週期每秒。因此，對於投影影像200，投影設備100需要大於360個幀每秒。In this embodiment, the LCoS panel 120 sequentially displays the first shaking image 210 and the second shaking image 220 . Each dithered image can represent a different color image. Since there are three basic colors (such as red, green, and blue), two dithering images, and two polarity frames, a display cycle consists of 12 frames. More than 30 cycles per second are required to produce a flicker-free and smooth display image. Therefore, for projecting the image 200, the projection device 100 requires more than 360 frames per second.

圖2示出根據本發明的實施例的包含多個像素的LCoS面板的示意圖。圖3示出根據本發明的實施例的LCoS面板的驅動電路的示意圖。參考圖2和圖3，LCoS面板120包含多個像素124。像素124中的每一個包含四個子像素。舉例來說，圖2中所示出的子像素電極A1、子像素電極A2、子像素電極A6以及子像素電極A7指示像素124_1包含四個子像素。像素群組126_1包含多個第一子像素電極A1到第一子像素電極A4、第一子像素電極A6到第一子像素電極A9、第一子像素電極A11到第一子像素電極A14以及第一子像素電極A16到第一子像素電極A19且顯示第一抖動影像210。像素群組126_2包含多個第二子像素電極A7到第二子像素電極A10、第二子像素電極A12到第二子像素電極A15、第二子像素電極A17到第二子像素電極A20以及第二子像素電極A22到第二子像素電極A25且顯示第二抖動影像220。Fig. 2 shows a schematic diagram of an LCoS panel comprising a plurality of pixels according to an embodiment of the present invention. FIG. 3 shows a schematic diagram of a driving circuit of an LCoS panel according to an embodiment of the present invention. Referring to FIGS. 2 and 3 , the LCoS panel 120 includes a plurality of pixels 124 . Each of pixels 124 includes four sub-pixels. For example, the sub-pixel electrode A1 , the sub-pixel electrode A2 , the sub-pixel electrode A6 and the sub-pixel electrode A7 shown in FIG. 2 indicate that the pixel 124_1 includes four sub-pixels. The pixel group 126_1 includes a plurality of first sub-pixel electrodes A1 to A4, first sub-pixel electrodes A6 to A9, first sub-pixel electrodes A11 to A14, and a plurality of first sub-pixel electrodes A1 to A14. A sub-pixel electrode A16 is connected to a first sub-pixel electrode A19 and displays a first shaking image 210 . The pixel group 126_2 includes a plurality of second sub-pixel electrodes A7 to A10, second sub-pixel electrodes A12 to A15, second sub-pixel electrodes A17 to A20, and a plurality of second sub-pixel electrodes A17 to A20. The second sub-pixel electrode A22 to the second sub-pixel electrode A25 display a second dithering image 220 .

LCoS面板120包含多個驅動電路122_1、驅動電路122_2、驅動電路122_3以及驅動電路122_4。在第一資料載入階段中，像素電壓Vp鎖存於每一驅動電路的第一儲存電容器C1中。在第一顯示階段中，鎖存於第一儲存電容器C1中的像素電壓Vp被傳輸以驅動像素群組126_1來顯示第一抖動影像210，其中第一顯示階段在第一資料載入階段之後。類似地，在第二資料載入階段中，像素電壓Vp鎖存於每一驅動電路的第二儲存電容器C2中。在第二顯示階段中，鎖存於第二儲存電容器C2中的像素電壓Vp被傳輸以驅動像素群組126_2來顯示第二抖動影像220，其中第二顯示階段在第二資料載入階段之後。The LCoS panel 120 includes a plurality of driving circuits 122_1 , 122_2 , 122_3 and 122_4 . In the first data loading phase, the pixel voltage Vp is latched in the first storage capacitor C1 of each driving circuit. In the first display stage, the pixel voltage Vp latched in the first storage capacitor C1 is transmitted to drive the pixel group 126_1 to display the first dithering image 210 , wherein the first display stage is after the first data loading stage. Similarly, in the second data loading phase, the pixel voltage Vp is latched in the second storage capacitor C2 of each driving circuit. In the second display stage, the pixel voltage Vp latched in the second storage capacitor C2 is transmitted to drive the pixel group 126_2 to display the second dithering image 220 , wherein the second display stage is after the second data loading stage.

應注意，當像素電壓Vp鎖存於第一儲存電容器C1中時，鎖存於第二儲存電容器C2中的像素電壓Vp被傳輸以驅動像素群組126_2。另一方面，當像素電壓Vp鎖存於第二儲存電容器C2中時，鎖存於第一儲存電容器C1中的像素電壓Vp被傳輸以驅動像素群組126_1。It should be noted that when the pixel voltage Vp is latched in the first storage capacitor C1, the pixel voltage Vp latched in the second storage capacitor C2 is transmitted to drive the pixel group 126_2. On the other hand, when the pixel voltage Vp is latched in the second storage capacitor C2, the pixel voltage Vp latched in the first storage capacitor C1 is transmitted to drive the pixel group 126_1.

在本實施例中，驅動電路中的每一個包含第一驅動路線和第二驅動路線。以驅動電路122_1為例，驅動電路122_1包含如圖4中所示出的第一驅動路線221和第二驅動路線222。圖4示出驅動電路122_1的示意圖，且圖5示出由驅動電路122_1驅動的兩個像素124_1和像素124_2的示意圖。參考圖4和圖5，第一驅動路線221和第二驅動路線222配置成根據像素電壓Vp來驅動對應子像素電極且分別確定第一抖動影像210和第二抖動影像220的顯示內容。In this embodiment, each of the driving circuits includes a first driving line and a second driving line. Taking the driving circuit 122_1 as an example, the driving circuit 122_1 includes a first driving line 221 and a second driving line 222 as shown in FIG. 4 . FIG. 4 shows a schematic diagram of the driving circuit 122_1 , and FIG. 5 shows a schematic diagram of two pixels 124_1 and 124_2 driven by the driving circuit 122_1 . Referring to FIG. 4 and FIG. 5 , the first driving line 221 and the second driving line 222 are configured to drive the corresponding sub-pixel electrodes according to the pixel voltage Vp and determine the display content of the first dithering image 210 and the second dithering image 220 respectively.

舉例來說，第一驅動路線221在第一顯示階段中根據像素電壓Vp來驅動第一子像素電極A1、第一子像素電極A2、第一子像素電極A6以及第一子像素電極A7，使得對應子像素顯示影像。因此，可確定第一抖動影像210的顯示內容。類似地，第二驅動路線222在不同於第一顯示階段的第二顯示階段中根據像素電壓Vp來驅動第二子像素電極A7、第二子像素電極A8、第二子像素電極A12以及第二子像素電極A13，使得對應子像素顯示影像。因此，可確定第二抖動影像220的顯示內容。在本實施例中，第一子像素電極中的至少一個與第二子像素電極中的至少一個相同。舉例來說，第一子像素電極A1、第一子像素電極A2、第一子像素電極A6以及第一子像素電極A7中的子像素電極A7與第二子像素電極A7、第二子像素電極A8、第二子像素電極A12以及第二子像素電極A13中的子像素電極A7相同。For example, the first driving route 221 drives the first sub-pixel electrode A1, the first sub-pixel electrode A2, the first sub-pixel electrode A6, and the first sub-pixel electrode A7 according to the pixel voltage Vp in the first display stage, so that The corresponding sub-pixels display images. Therefore, the display content of the first shaking image 210 can be determined. Similarly, the second driving route 222 drives the second sub-pixel electrode A7, the second sub-pixel electrode A8, the second sub-pixel electrode A12 and the second The sub-pixel electrodes A13 enable the corresponding sub-pixels to display images. Therefore, the display content of the second shaking image 220 can be determined.

The first driving route 221 and the second driving route 222 are selected from the same driving circuit 122_1 , but the invention is not limited thereto. The first driving route and the second driving route can be selected from two different driving circuits.

The first driving route of the driving circuit 122_2 and the second driving route of the driving circuit 122_1 are selected from two different driving circuits.

That is, subpixel electrode A7 to subpixel electrode A9, subpixel electrode A12 to subpixel electrode 14, and subpixel electrode A17 to subpixel electrode A19 (parts of subpixel electrode A1 to subpixel electrode A25) are coupled to the first The driving route and the second driving route, and the first driving route and the second driving route are selected from the same driving circuit or two different driving circuits.

像素124_1和像素124_2分別包含四個子像素128。子像素128中的每一個包含耦合於子像素電極與共同電極之間的像素電容器C3。舉例來說，子像素128_1包含耦合於子像素電極A1與共同電極VCOM之間的像素電容器C3。The pixel 124_1 and the pixel 124_2 respectively include four sub-pixels 128 . Each of the subpixels 128 includes a pixel capacitor C3 coupled between the subpixel electrode and the common electrode. For example, the sub-pixel 128_1 includes a pixel capacitor C3 coupled between the sub-pixel electrode A1 and the common electrode VCOM.

在本實施例中，第一驅動路線和第二驅動路線中的每一個包含至少兩個開關電路和電容器電路。舉例來說，第一驅動路線221包含兩個開關電路SW1和開關電路SW2以及電容器電路C1，且電容器電路C1包含儲存電容器（第一儲存電容器）。第二驅動路線222包含兩個開關電路SW3和開關電路SW4以及電容器電路C2，且電容器電路C2包含儲存電容器（第二儲存電容器）。開關電路的數目和電容器電路的數目並不意圖限制本發明。In this embodiment, each of the first driving route and the second driving route includes at least two switch circuits and capacitor circuits. For example, the first driving line 221 includes two switch circuits SW1 and SW2 and a capacitor circuit C1, and the capacitor circuit C1 includes a storage capacitor (first storage capacitor). The second drive line 222 includes two switch circuits SW3 and SW4 and a capacitor circuit C2, and the capacitor circuit C2 includes a storage capacitor (second storage capacitor). The number of switch circuits and the number of capacitor circuits are not intended to limit the invention.

在本實施例中，第一驅動路線221和第二驅動路線222在不同階段中操作。當第一驅動路線221在資料載入階段中操作時，第二驅動路線在顯示階段中操作。當第一驅動路線221在顯示階段中操作時，第二驅動路線222在資料載入階段中操作。換句話說，第一驅動路線221和第二驅動路線222並不在相同階段中操作。In this embodiment, the first driving route 221 and the second driving route 222 operate in different stages. When the first driving route 221 operates in the data loading phase, the second driving route operates in the displaying phase. When the first driving route 221 operates in the display phase, the second driving route 222 operates in the data loading phase. In other words, the first driving route 221 and the second driving route 222 do not operate in the same phase.

具體來說，對於第一驅動路線221，第一開關電路SW1在資料載入階段中接通且第二開關電路SW2斷開，且像素電壓Vp鎖存於第一儲存電容器C1中。隨後，第一開關電路SW1在顯示階段中斷開且第二開關電路SW2接通，且鎖存於第一儲存電容器C1中的像素電壓Vp被傳輸以驅動第一子像素電極A1、第一子像素電極A2、第一子像素電極A6以及第一子像素電極A7。顯示階段在資料載入階段之後。Specifically, for the first driving route 221 , the first switch circuit SW1 is turned on and the second switch circuit SW2 is turned off during the data loading phase, and the pixel voltage Vp is latched in the first storage capacitor C1 . Subsequently, the first switch circuit SW1 is turned off and the second switch circuit SW2 is turned on during the display phase, and the pixel voltage Vp latched in the first storage capacitor C1 is transmitted to drive the first sub-pixel electrode A1, the first sub-pixel The pixel electrode A2, the first sub-pixel electrode A6 and the first sub-pixel electrode A7. The display phase follows the data loading phase.

當第一驅動路線221在顯示階段中操作時，第二驅動路線在資料載入階段中操作。對於第二驅動路線222，第三開關電路SW3在資料載入階段中接通且第四開關電路SW4斷開，且像素電壓Vp鎖存於第二儲存電容器C2中。隨後，第三開關電路SW3在顯示階段中斷開且第四開關電路SW4接通，且鎖存於第二儲存電容器C2中的像素電壓Vp被傳輸以驅動第二子像素電極A7、第二子像素電極A8、第二子像素電極A12以及第二子像素電極A13。When the first driving route 221 operates in the display phase, the second driving route operates in the data loading phase. For the second driving route 222, the third switch circuit SW3 is turned on and the fourth switch circuit SW4 is turned off during the data loading phase, and the pixel voltage Vp is latched in the second storage capacitor C2. Subsequently, the third switch circuit SW3 is turned off and the fourth switch circuit SW4 is turned on in the display phase, and the pixel voltage Vp latched in the second storage capacitor C2 is transmitted to drive the second sub-pixel electrode A7, the second sub-pixel The pixel electrode A8, the second sub-pixel electrode A12 and the second sub-pixel electrode A13.

在圖5中，第一驅動路線221中的子像素電極A1、子像素電極A2、子像素電極A6以及子像素電極A7不完全與第二驅動路線222中的子像素電極A7、子像素電極A8、子像素電極A12以及子像素電極A13相同。在本實施例中，像素124_2相對於像素124_1移位一個子像素。在一實施例中，所述移位可大於一個子像素。移位可以是水準、垂直或成對角線的。In FIG. 5 , the sub-pixel electrode A1, sub-pixel electrode A2, sub-pixel electrode A6 and sub-pixel electrode A7 in the first driving route 221 are not completely consistent with the sub-pixel electrode A7 and sub-pixel electrode A8 in the second driving route 222. , the sub-pixel electrode A12 and the sub-pixel electrode A13 are the same. In this embodiment, the pixel 124_2 is shifted by one sub-pixel relative to the pixel 124_1 . In an embodiment, the shift may be greater than one sub-pixel. Shifts can be horizontal, vertical or diagonal.

Referring to FIG. 4 , FIG. 6A , FIG. 6B and FIG. 6C , the switch circuit SW1 , switch circuit SW2 , switch circuit SW3 or switch circuit SW4 may include one or more switch devices 610 , 620 or 630 . The number of switching devices of the switching circuit SW1 , switching circuit SW2 , switching circuit SW3 or switching circuit SW4 is not intended to limit the invention. The switching device 610 is a Complementary Metal-Oxide-Semiconductor (CMOS) type switch and is controlled by a control signal S1 and a control signal S2 . The switching device 620 is an N-Metal-Oxide-Semiconductor (NMOS) type switch and is controlled by a control signal S2 . The switching device 630 is a P-Metal-Oxide-Semiconductor (PMOS) type switch and is controlled by the control signal S1 .

綜上所述，在本發明的示範性實施例中，提供一種單元內振動（in-cell vibration）方法。每一像素包含四個子像素。通過引入新底板電路設計和時序控制，顯示影像實際上在LCoS面板內移位一半像素。通過使用此種方法，可去除外部電子移位裝置，且投影設備可與普通AR投影系統一樣小。不需要額外光學裝置來實現本發明的示範性實施例中的子像素抖動。因此，包含LCoS面板的投影設備的體積小，且投影設備可提供高影像解析度。To sum up, in an exemplary embodiment of the present invention, an in-cell vibration method is provided. Each pixel contains four sub-pixels. By introducing a new backplane circuit design and timing control, the display image is actually shifted by half a pixel within the LCoS panel. By using this method, the external electronic shifting device can be eliminated, and the projection device can be as small as a general AR projection system. No additional optics are required to achieve sub-pixel dithering in exemplary embodiments of the present invention. Therefore, the projection device including the LCoS panel is small in size, and the projection device can provide high image resolution.
