本發明是有關於一種顯示技術，且特別是有關於一種半穿反顯示面板的顯示方法及使用其之電子裝置。The present invention relates to a display technology, and more particularly to a display method for a transflective display panel and an electronic device using the same.
電子裝置的種類與日俱增，所支援的功能也日漸多樣化。在所支援的功能愈來愈多元的狀況下，電量的消耗也隨之增加，電子裝置的續航力成為消費者選購時的考量點，因此省電功能也成為開發者一個重要的課題。The variety of electronic devices is increasing day by day, and the functions supported are becoming more diverse. As the supported functions become more diverse, the consumption of electricity increases, and the endurance of electronic devices becomes a consideration for consumers to purchase. Therefore, the power-saving function has become an important issue for developers.
「半穿反(transflective)顯示器」即是適合應用於電子裝置的顯示器。除了與一般顯示器一樣使用背光做為顯示用光源，半穿反顯示器也可以同時反射外在環境光以作為顯示用光源。因此，半穿反顯示器可以減少背光光源的使用，達到省電的效果。並且，在戶外陽光下等外在環境光強度很足夠的條件下，即使完全關閉背光光源且單靠反射環境光做為顯示用光源，也能使半穿反顯示器保有基本的可視性，達到更佳的省電效果。A "transflective display" is a display suitable for use in an electronic device. In addition to using the backlight as a light source for display as with a general display, the transflective display can also reflect external ambient light as a light source for display. Therefore, the semi-transflective display can reduce the use of the backlight source and achieve the effect of power saving. Moreover, under the condition that the external ambient light intensity is sufficient under outdoor sunlight, even if the backlight source is completely turned off and the reflected ambient light is used as the display light source, the semi-transflective display can maintain basic visibility and achieve more. Good power saving effect.
但是，在單靠反射環境光作為顯示用光源的時候，若是半穿反顯示器的畫面顯示內容中有較暗的區域，有可能因為關閉背光而導致使用者難以分辨畫面中的細節，造成不好的使用體驗。However, when reflecting the ambient light alone as the light source for display, if there is a darker area in the screen display content of the semi-transmissive display, it may be difficult for the user to distinguish the details in the picture because the backlight is turned off, resulting in a bad The experience of using.
有鑑於此，本發明提供一種電子裝置及影像調整方法，能夠在關閉背光光源的情況下兼顧畫面的顯示品質。In view of the above, the present invention provides an electronic device and an image adjustment method capable of taking into consideration the display quality of a screen when the backlight source is turned off.

基於上述，本發明實施例所述的電子裝置及其影像調整方法可在半穿反顯示面板的背光光源關閉時分析半穿反顯示面板所顯示的當前影像，藉以在當前影像的暗區程度較高時(也就是，當前影像主要由較暗像素呈現)來調整當前影像中的像素亮度值，藉以突顯當前影像在暗區域中的細節。藉此，可使半穿反顯示面板在單靠反射環境光作為光源時能夠藉由自動化地影像調整來呈現當前畫面的暗區域細節，以在省電的同時兼顧畫面的顯示品質。Based on the above, the electronic device and the image adjustment method thereof according to the embodiments of the present invention can analyze the current image displayed by the transflective display panel when the backlight source of the transflective display panel is turned off, so that the dark area of the current image is compared. The high time (that is, the current image is mainly represented by darker pixels) adjusts the pixel brightness value in the current image to highlight the details of the current image in the dark area. Thereby, the semi-transmissive display panel can display the dark area details of the current picture by automatically adjusting the image when the reflected ambient light is used as the light source, so as to balance the display quality of the picture while saving power.

處理單元110可以是中央處理器、繪圖處理器、處理晶片…等。半穿反顯示面板160可以是任何使用半穿反顯示技術的液晶顯示面板。所謂的半穿反顯示技術是一種同時利用來自背光模組的穿透光以及來自環境光源的反射光，使顯示器可在強烈環境光下仍有可視性的顯示技術。其原理是將面板中的畫素分為反射區與穿透區兩部分，其中反射區內加上一層金屬反射層來達到反射的目的，也可藉由停止彩色濾光片的作用以避免降低反射率。Processing unit 110 may be a central processing unit, a graphics processor, a processing chip, etc. The transflective display panel 160 can be any liquid crystal display panel that uses a transflective display technology. The so-called semi-transflective display technology is a display technology that simultaneously utilizes the transmitted light from the backlight module and the reflected light from the ambient light source to make the display still visible under strong ambient light. The principle is that the pixels in the panel are divided into two parts: a reflection area and a penetration area, wherein a reflection layer is added to the reflection area to achieve the purpose of reflection, and the color filter can be stopped to avoid the reduction. Reflectivity.
環境光感應器120可藉由光感測器150獲得電子裝置100周遭的環境光強度，處理單元110透過環境光感應器120獲得環境光強度的數據。處理單元110並可透過背光調整模組130對半穿反顯示面板160調整背光強度，以及可透過數位調整顯示模組140對半穿反顯示面板160進行影像調整。其中背光調整模組130可以是任何具有對顯示面板進行背光強度調整能力的軟體架構或硬體電路，數位顯示調整模組140可以是任何對顯示面板的顯示內容如亮度、對比度等具調整能力的軟體架構或硬體電路。The ambient light sensor 120 can obtain ambient light intensity around the electronic device 100 by the light sensor 150, and the processing unit 110 obtains data of the ambient light intensity through the ambient light sensor 120.

The digital display adjustment module 140 can be any adjustment capability for the display content of the display panel, such as brightness and contrast. Software architecture or hardware circuits.
圖2是依照本發明一實施例的顯示方法的流程圖。請參照圖1與圖2，在步驟S210中，處理單元110會檢查電子裝置100是否已開啟自動調整背光設定。若電子裝置100未開啟自動調整背光設定(步驟S210為否)，則表示電子裝置100不需要進行此功能。若電子裝置100已開啟自動調整背光設定(步驟S210為是)，則進入步驟S220，環境光感應器120藉由光感測器150檢測電子裝置100周邊的環境光強度，並將此環境光強度資訊傳送給處理單元110，進入步驟S230。2 is a flow chart of a display method in accordance with an embodiment of the present invention. Referring to FIG. 1 and FIG. 2, in step S210, the processing unit 110 checks whether the electronic device 100 has turned on the automatic adjustment backlight setting. If the electronic device 100 is not turned on to automatically adjust the backlight setting (NO in step S210), it means that the electronic device 100 does not need to perform this function. If the electronic device 100 has turned on the automatic adjustment backlight setting (YES in step S210), the process proceeds to step S220, and the ambient light sensor 120 detects the ambient light intensity around the electronic device 100 by using the light sensor 150, and the ambient light intensity is obtained. The information is transmitted to the processing unit 110, and the flow proceeds to step S230.
在步驟S230中，處理單元110判斷環境光強度是否大於第一門檻值。若環境光強度不大於第一門檻值(步驟S230為否)，則回到步驟S210。若環境光強度大於第一門檻值(步驟S230為是)，則進入步驟S240，處理單元110透過背光調整模組130關閉半穿反顯示面板160的背光光源。接著進入步驟S250。在步驟S250中，處理單元110分析半穿反顯示面板160所顯示的當前影像，以判斷當前影像中的暗區程度，並進入步驟S260判斷暗區程度是否大於第三門檻值。若判斷暗區程度不大於第三門檻值(步驟S260為否)，則回到步驟S210。若判斷暗區程度大於第三門檻值(步驟S260為是)，則進入步驟S270，處理單元110透過數位調整顯示模組140對半穿反顯示面板160所顯示的當前影像進行像素灰階值的調整。In step S230, the processing unit 110 determines whether the ambient light intensity is greater than the first threshold. If the ambient light intensity is not greater than the first threshold value (NO in step S230), the process returns to step S210. If the ambient light intensity is greater than the first threshold (YES in step S230), the process proceeds to step S240, and the processing unit 110 turns off the backlight source of the transflective display panel 160 through the backlight adjustment module 130. Then, the process proceeds to step S250. In step S250, the processing unit 110 analyzes the current image displayed by the transflective display panel 160 to determine the extent of the dark region in the current image, and proceeds to step S260 to determine whether the extent of the dark region is greater than the third threshold. If it is determined that the dark zone level is not greater than the third threshold value (NO in step S260), the process returns to step S210. If it is determined that the dark area is greater than the third threshold (YES in step S260), then the process proceeds to step S270, and the processing unit 110 performs the pixel grayscale value on the current image displayed by the transflective display panel 160 through the digital adjustment display module 140. Adjustment.
圖3是依照本發明一實施例的半穿反顯示面板背光亮度與環境光強度的對應示意圖。請參照圖3，橫軸a為環境光強度，單位為lux(意即燭光·球面度/平方米，cd·sr/m2)，縱軸L為半穿反顯示面板160的亮度，單位為nits(意即燭光/平方米，cd/m2)。三條虛線310、320、330代表顯示面板隨著環境光強度的變化所應具備的基本亮度標準，其意義分別為「符合可見」、「可見且清楚」以及「最明亮」。以虛線310「符合可見」為例，在環境光強度為2000 lux的場合，顯示面板的亮度至少要超過100 nits，顯示內容對人眼來說才算是符合可見的標準。FIG. 3 is a schematic diagram of correspondence between backlight brightness and ambient light intensity of a transflective display panel according to an embodiment of the invention. Referring to FIG. 3, the horizontal axis a is ambient light intensity, the unit is lux (meaning candlelight/sphericity/square meter, cd·sr/m2 ), and the vertical axis L is the brightness of the semi-transmissive display panel 160, and the unit is Nits (meaning candlelight / square meter, cd / m2 ). The three dashed lines 310, 320, and 330 represent the basic brightness standards that the display panel should have as the ambient light intensity changes. The meanings are "fit visible,""visible and clear," and "brightest." Taking the dotted line 310 "conformity visible" as an example, when the ambient light intensity is 2000 lux, the brightness of the display panel should be at least 100 nits, and the display content is a visible standard for the human eye.
請繼續參照圖3。一般室內環境光源低於1000 lux，且大多為500~700 lux。而在環境光源大於900 lux的室外環境，環境光強度已足夠讓半穿反顯示面板單靠反射模式顯示，因此在本實施例中將第二門檻值設定為900 lux。圖中實線340為此實施例中半穿反顯示面板160的實際亮度曲線，實線340在環境光強度約0~900 lux的區段為正斜率，因為此階段中半穿反顯示面板160同時藉由背光及反射環境光顯示，而在區域350處環境光強度約900~950 lux，處理單元110透過背光調整模組130關閉半穿反顯示面板160的背光光源，使得半穿反顯示面板160僅靠反射環境光顯示，因此在區域350處半穿反顯示面板160的總亮度反而減少，實線340轉變為負斜率，但整體來說依然滿足符合人眼可見的標準。需要注意的是，關於環境光強度的第一門檻值可依照本發明實施例者的需求適度地調整，本發明不對此做限制。Please continue to refer to Figure 3. Typical indoor ambient light sources are less than 1000 lux and are mostly 500-700 lux. In an outdoor environment where the ambient light source is greater than 900 lux, the ambient light intensity is sufficient for the transflective display panel to be displayed in reflective mode alone, so in this embodiment the second threshold is set to 900 lux. The solid line 340 in the figure is the actual brightness curve of the transflective display panel 160 in this embodiment, and the solid line 340 has a positive slope in the section where the ambient light intensity is about 0 to 900 lux, because the trans-display panel 160 is half-transposed in this stage. At the same time, the backlight unit and the reflective ambient light display, and the ambient light intensity at the area 350 is about 900-950 lux, and the processing unit 110 turns off the backlight source of the trans-display panel 160 through the backlight adjustment module 130, so that the trans-display panel is semi-transparent. 160 is only reflected by the reflected ambient light, so the total brightness of the trans-display panel 160 is reduced at the region 350, and the solid line 340 is converted to a negative slope, but overall it still meets the criteria that are visible to the human eye. It should be noted that the first threshold value for the ambient light intensity may be appropriately adjusted according to the needs of the embodiments of the present invention, and the present invention does not limit this.
請繼續參照圖2，在步驟S240對半穿反顯示面板160的背光光源進行關閉後，進入步驟S250，處理單元110會對當前影像的暗區程度進行判斷。在本發明的一實施例中，暗區程度的判斷是藉由計算當前影像中暗像素點的數量與所有像素點的數量的比值。Referring to FIG. 2, after the backlight source of the transflective display panel 160 is turned off in step S240, the process proceeds to step S250, and the processing unit 110 determines the dark area of the current image. In an embodiment of the invention, the degree of dark area is determined by calculating the ratio of the number of dark pixels in the current image to the number of all pixels.
圖4是依照本發明一實施例的計算畫面顯示內容中暗像素點數量的流程圖。請參照圖4，在步驟S410中，處理單元110先將當前影像轉換為以灰階呈現的灰階影像。接著進入步驟S420，處理單元110計算此灰階影像中灰階值未達第二門檻值的像素個數。在本實施例中，將顯示畫面轉換成256灰階，畫面中每個像素的值介於0~255之間。接著處理單元110對每個像素進行灰階值大小的判斷，在本實施例中第二門檻值設定為最大值的1/4，灰階值未達最大值的1/4的像素將會被判定為暗像素點，意即灰階值介於0~63之間的像素將被判定為暗像素點。基於此判斷，當前影像中的暗像素點的個數將會被確定。4 is a flow chart for calculating the number of dark pixels in a display content of a screen, in accordance with an embodiment of the present invention. Referring to FIG. 4, in step S410, the processing unit 110 first converts the current image into a grayscale image presented in grayscale. Next, proceeding to step S420, the processing unit 110 calculates the number of pixels in the grayscale image that the grayscale value does not reach the second threshold. In this embodiment, the display picture is converted into 256 gray levels, and the value of each pixel in the picture is between 0 and 255. Then, the processing unit 110 determines the grayscale value of each pixel. In this embodiment, the second threshold is set to 1/4 of the maximum value, and the pixel whose grayscale value is less than 1/4 of the maximum value is to be It is determined that it is a dark pixel point, that is, a pixel whose gray scale value is between 0 and 63 will be determined as a dark pixel point. Based on this judgment, the number of dark pixel points in the current image will be determined.
請繼續參照圖2。確定當前影像中暗像素點的數量後，在步驟S250中處理單元110便藉由此暗像素點數量與畫面顯示內容中所有像素點數量的比值計算出暗區程度，並在步驟S260中判斷此暗區程度是否大於第三門檻值。在此實施例中第三門檻值設定為33%，意即當前影像中暗像素點的數量超過全體像素數的33%的場合，便判定此影像有一定程度的細節在半穿反顯示面板160的背光光源被關閉的狀態下難以被人眼所辨別，因此進入步驟S270，對當前影像進行像素灰階值調整。Please continue to refer to Figure 2. After determining the number of dark pixel points in the current image, the processing unit 110 calculates the dark area degree by the ratio of the number of dark pixel points to the number of all pixel points in the screen display content in step S250, and determines this in step S260. Whether the dark area is greater than the third threshold. In this embodiment, the third threshold is set to 33%, that is, when the number of dark pixels in the current image exceeds 33% of the total number of pixels, it is determined that the image has a certain degree of detail in the trans-display panel 160. When the backlight source is turned off, it is difficult to be discerned by the human eye. Therefore, the process proceeds to step S270 to adjust the pixel grayscale value of the current image.
圖5是依照本發明一實施例的像素灰階值調整方法的伽瑪校正曲線的示意圖。在此實施例中，設定了與三組不同預設環境光強度對應的伽瑪校正曲線。圖5中橫軸是當前影像像素的輸入灰階亮度值，縱軸是當前影像像素的輸出亮度值(其值同時正規化到0~1區間)。其中曲線530為一般顯示器所使用的伽瑪校正曲線，其伽瑪值(gamma value)為2.2；曲線520是基於伽瑪值等於2.0的伽瑪校正曲線而更強調對中暗亮度及暗亮度的像素進行亮度調整的伽瑪校正曲線；曲線510是基於伽瑪值等於1.8的伽瑪校正曲線而更強調對中暗亮度及暗亮度的像素進行亮度調整的伽瑪校正曲線。在此實施例中，環境光強度最弱的場合會套用伽瑪值2.2的曲線530，環境光強度最強的場合會套用曲線510，環境光強度介於中間的場合則套用曲線520。處理單元110依據電子裝置100的當前環境光強度，在此三組曲線中選出對應的一組伽瑪校正曲線，對當前影像中每一個像素的亮度值，或是對像素在所對應的色彩空間中的分量進行調整。FIG. 5 is a schematic diagram of a gamma correction curve of a pixel grayscale value adjustment method according to an embodiment of the invention. In this embodiment, a gamma correction curve corresponding to three different sets of preset ambient light intensities is set. In FIG. 5, the horizontal axis is the input grayscale luminance value of the current image pixel, and the vertical axis is the output luminance value of the current image pixel (the value is simultaneously normalized to the 0~1 interval). Curve 530 is a gamma correction curve used by a general display, and its gamma value is 2.2; curve 520 is based on a gamma correction curve with a gamma value equal to 2.0 and more emphasis on the dark and dark brightness of the center. The pixel performs a gamma correction curve for brightness adjustment; the curve 510 is a gamma correction curve that emphasizes brightness adjustment of pixels for medium dark and dark brightness based on a gamma correction curve having a gamma value equal to 1.8. In this embodiment, the curve 530 with a gamma value of 2.2 is applied in the case where the ambient light intensity is the weakest, and the curve 510 is applied in the case where the ambient light intensity is the strongest, and the curve 520 is applied when the ambient light intensity is in the middle. The processing unit 110 selects a corresponding set of gamma correction curves among the three sets of curves according to the current ambient light intensity of the electronic device 100, and the brightness value of each pixel in the current image, or the pixel in the corresponding color space. The components in the adjustment are adjusted.
圖6是依照本發明一實施例的進行像素灰階值調整前後畫面顯示內容的示意圖。請先參照圖6中610，此畫面是在電子裝置100已將半穿反顯示面板160之背光光源關閉的場合，僅靠反射環境光所顯示的戶外場景圖，畫面中偏暗區域的細節部份幾乎無法被人眼所識別。620是電子裝置100經過數位顯示調整模組140進行像素灰階值調整後所呈現的畫面，畫面中大部份的區域幾乎都可被人眼所識別。FIG. 6 is a schematic diagram of screen display content before and after pixel grayscale value adjustment according to an embodiment of the invention. Please refer to FIG. 6 at 610. This screen is an outdoor scene map displayed only by reflecting ambient light when the electronic device 100 has turned off the backlight source of the trans-display panel 160. The details of the dark area in the screen are as follows. It is almost impossible to be recognized by the human eye. 620 is a screen that is displayed after the electronic device 100 performs pixel grayscale adjustment by the digital display adjustment module 140. Most of the regions in the screen can be recognized by the human eye.
綜上所述，本發明所提供的電子裝置及影像調整方法可在半穿反顯示面板的背光光源關閉時，分析半穿反顯示面板所顯示的當前影像，藉以在當前影像主要由較暗像素呈現時調整當前影像中的像素亮度值，以使當前影像在暗區域中的細節能夠被使用者所辨識。藉此，可使半穿反顯示面板在單靠反射環境光作為光源時能夠自動化地影像調整來呈現當前畫面的暗區域細節，以在省電的同時兼顧畫面的顯示品質。In summary, the electronic device and the image adjustment method provided by the present invention can analyze the current image displayed by the transflective display panel when the backlight source of the trans-display panel is turned off, so that the current image is mainly composed of dark pixels. The pixel brightness value in the current image is adjusted during rendering so that the details of the current image in the dark area can be recognized by the user. Thereby, the semi-transmissive display panel can automatically adjust the image to present the dark area details of the current picture when the reflected ambient light is used as the light source, so as to balance the display quality of the picture while saving power.
