When the brightness of the surrounding environment of the electronic device 1 belongs to the first brightness range, step 303 is performed. When the brightness of the surrounding environment of the electronic device 1 does not belong to the first brightness range, step 304 is performed.

步驟309，當所述周圍環境的亮度屬於所述第四亮度範圍時，所述調節模組123將該背光模組130的當前亮度調整為第四亮度值(例如，302cd/m2)，並可將所述背光模組130的當前亮度調節範圍調整為第四亮度調節範圍(例如，介於151cd/m2與420cd/m2之間)。 Step 309, when the brightness of the surrounding environment belongs to the fourth brightness range, the adjustment module 123 adjusts the current brightness of the backlight module 130 to a fourth brightness value (for example, 302 cd/m 2 ), and The current brightness adjustment range of the backlight module 130 can be adjusted to a fourth brightness adjustment range (for example, between 151 cd/m 2 and 420 cd/m 2 ).
在一個實施例中，當所述周圍環境的亮度屬於所述第四亮度範圍時，所述調節模組123還根據所述電子設備1的周圍環境的色溫值調節所述顯示螢幕13的色溫值。 In an embodiment, when the brightness of the surrounding environment belongs to the fourth brightness range, the adjustment module 123 further adjusts the color temperature value of the display screen 13 according to the color temperature value of the surrounding environment of the electronic device 1. .
具體地，當所述電子設備1的周圍環境的色溫值屬於所述第一色溫範圍(例如，小於或等於3500K)時，所述調節模組123將所述顯示螢幕13的色溫值調節為所述第一色溫值(例如，6488K)。 Specifically, when the color temperature value of the surrounding environment of the electronic device 1 belongs to the first color temperature range (for example, less than or equal to 3500K), the adjustment module 123 adjusts the color temperature value of the display screen 13 to The first color temperature value (for example, 6488K) is described.
當所述電子設備1的周圍環境的色溫值屬於所述第二色溫範圍(例如，介於3501K與7300K之間)時，所述調節模組123將所述顯示螢幕13的色溫值調節為所述第二色溫值(例如，7357K)。所述第二色溫範圍所對應的色溫值大於所述第一色溫範圍所對應的色溫值。 When the color temperature value of the surrounding environment of the electronic device 1 belongs to the second color temperature range (for example, between 3501K and 7300K), the adjustment module 123 adjusts the color temperature value of the display screen 13 to The second color temperature value (for example, 7357K) is described. The color temperature value corresponding to the second color temperature range is greater than the color temperature value corresponding to the first color temperature range.
當所述電子設備1的周圍環境的色溫值屬於所述第三色溫範圍(例如，大於7300K)時，所述調節模組123將所述顯示螢幕13的色溫值調節為所述第三色溫值(例如，8641K)。所述第三色溫範圍所對應的色溫值大於所述第 二色溫範圍所對應的色溫值。 When the color temperature value of the surrounding environment of the electronic device 1 belongs to the third color temperature range (for example, greater than 7300K), the adjustment module 123 adjusts the color temperature value of the display screen 13 to the third color temperature value. (for example, 8641K). The color temperature value corresponding to the third color temperature range is greater than the first The color temperature value corresponding to the two-color temperature range.
步驟310，當所述周圍環境的亮度不屬於所述第四亮度範圍時，所述判斷模組122確定該周圍環境的亮度屬於預設的第五亮度範圍(例如，大於10000Lux)。所述第五亮度範圍所對應的亮度大於所述第四亮度範圍所對應的亮度。執行完步驟310後執行步驟311。 Step 310: When the brightness of the surrounding environment does not belong to the fourth brightness range, the determining module 122 determines that the brightness of the surrounding environment belongs to a preset fifth brightness range (for example, greater than 10000 Lux). The brightness corresponding to the fifth brightness range is greater than the brightness corresponding to the fourth brightness range. After step 310 is performed, step 311 is performed.
步驟311，所述調節模組123將該背光模組130的當前亮度調整為第五亮度值(例如，345cd/m2)，並可將所述背光模組130當前亮度調節範圍設置為第五亮度調節範圍(例如，介於173cd/m2與600cd/m2之間)。 Step 311, the adjustment module 123 adjusts the current brightness of the backlight module 130 to a fifth brightness value (for example, 345 cd/m 2 ), and sets the current brightness adjustment range of the backlight module 130 to the fifth. The brightness adjustment range (for example, between 173 cd/m 2 and 600 cd/m 2 ).
於此實施例中，所述顯示螢幕13所顯示的圖像至少包含了一明亮部與一陰暗部，所述明亮部指在所述圖像中比所述陰暗部明亮之部分。所述調節模組123還將所述圖像的陰暗部所對應的灰階係數提高，藉以增加所述圖像在高亮度(例如，大於10000Lux)環境下的可閱讀性。 In this embodiment, the image displayed on the display screen 13 includes at least a bright portion and a dark portion, and the bright portion refers to a portion in the image that is brighter than the dark portion. The adjustment module 123 also increases the gray scale coefficient corresponding to the dark portion of the image, thereby increasing the readability of the image in a high brightness (eg, greater than 10000 Lux) environment.
最後所應說明的是，以上實施例僅用以說明本發明的技術方案而非限制，儘管參照以上較佳實施例對本發明進行了詳細說明，本領域的普通技術人員應當理解，可以對本發明的技術方案進行修改或等同替換都不應脫離本發明技術方案的精神和範圍。 It should be noted that the above embodiments are only intended to illustrate the technical solutions of the present invention and are not intended to be limiting, and the present invention will be described in detail with reference to the preferred embodiments thereof Modifications or equivalents of the technical solutions are not to be construed as a departure from the spirit and scope of the invention.
