數位化時代智慧醫療的來臨,更大尺寸、更高解析度以及更高顯示規格的醫療用顯示器需求是不可或缺的,其中,顯示器的色彩精確度管理更是不可忽視的環節。針對顯示器色彩校正,由於LED 光源在長時間的電流驅動下往往受電熱特性的影響,導致光功率下降甚至由於光源衰變程度不一,進而產生光色飄移的困擾,故需使用感測設備長時間測量顯示器光色變化。
考量感測器須固定在顯示器進行量測及其價格,本研究採用RGB色彩感測元件,並透過多項式回歸的方式並建立一系統化的校正及驗證流程,使RGB色彩感測元件再現標準儀器量測結果。
結果表明,就顯示器對色彩感測器而言,使用上述校正模型可達到簡單且較低的運算成本與高速的運算處理,並且可得到與目標值之∆Y在±2%的誤差範圍內、∆E*小於2的預測結果。


With the advent of smart healthcare in the digital age, larger sizes, higher resolutions, and higher display specifications are indispensable for the demand of medical displays. Among them, the color accuracy management of the display is a key point that cannot be ignored. For display color calibration, the LED light source is often affected by electrothermal effects under long-term current driving, resulting in a decrease in optical output, and even due to varying degrees of light source decay, which causes light color shift. Therefore, it is necessary to use a sensing device for a real time to measure the light color difference of the display.
Considering the sensor must be fixed on the display for measurement and its cost, we apply a RGB color sensor components, as well as using polynomial regression and finally establishing a systematic calibration and process. With our calibration method, the RGB color sensor can directly replace expensive standard color instruments.
The results show that, as far as the display is to the color sensor, the calibration model proposed in this thesis can achieve a simple way, low computing cost, and high-speed computing processing. It can get the prediction result with the target value of ∆Y within ±2% error range and ∆E less than 2.
