Taking the sampling display device 140A as an example, please refer to FIG. 2. The sampling display device 140A further includes a first backlight module 143A, a first brightness detection unit 144A, and a first processing unit 145A. The processing unit 145A is adapted to be connected to the screen correction. Device 120A.
本實施例的取樣顯示裝置140A經由第一處理單元145A以及畫面校正裝置120A產生一第一色彩補償值。請參照圖2，第一背光模組143A發出的 光束可以經由第一顯示面板141A形成為影像光束L1，畫面校正裝置120A可以在影像光束L1形成影像的表面上測量這些影像光束L1來產生一第一色彩量測值。第一處理單元145A比較此第一色彩量測值與第一標準色彩值。當畫面校正裝置120A所測到的影像光束L1所產生的第一色彩量測值與第一標準色彩值不同時，第一處理單元145A會重複調整第一顯示面板141A的顏色，並再經由畫面校正裝置120A測量，直到第一色彩量測值與第一標準色彩值相同，並在第一色彩量測值達到第一標準色彩值時根據第一顯示面板141A的顏色變化量紀錄為一第一色彩補償值。 The sampling display device 140A of this embodiment generates a first color compensation value through the first processing unit 145A and the frame correction device 120A. Please refer to FIG. 2. The light beam may be formed into an image light beam L1 via the first display panel 141A, and the frame correction device 120A may measure these image light beams L1 on the surface where the image light beam L1 forms an image to generate a first color measurement value. The first processing unit 145A compares this first color measurement value with a first standard color value. When the first color measurement value generated by the image beam L1 detected by the frame correction device 120A is different from the first standard color value, the first processing unit 145A repeatedly adjusts the color of the first display panel 141A, and then passes through the screen The calibration device 120A measures until the first color measurement value is the same as the first standard color value, and records a first color according to the color change amount of the first display panel 141A when the first color measurement value reaches the first standard color value. Color compensation value.
上述的第一顯示面板141A的顏色的調整方式例如是調整像素中對應至每個顏色的資料訊號的電壓，亦即施加於畫素電極上的電壓；較佳為分別校正三原色紅、綠、藍的資料訊號，亦即上述的第一色彩補償值包括第一紅色補償值、第一綠色補償值以及第一藍色補償值，以下將會再針對色彩補償值進行詳細說明。當第一色彩補償值產生時，第一處理單元145A將第一色彩補償值儲存於上傳資料並經由第一存取單元142A上傳至上述的遠端資料庫130。 The color adjustment method of the first display panel 141A described above is, for example, adjusting the voltage of the data signal corresponding to each color in the pixel, that is, the voltage applied to the pixel electrode; preferably, the three primary colors red, green, and blue are corrected separately The data signal, that is, the first color compensation value includes the first red compensation value, the first green compensation value, and the first blue compensation value. The color compensation value will be described in detail below. When the first color compensation value is generated, the first processing unit 145A stores the first color compensation value in the uploaded data and uploads the first color compensation value to the above-mentioned remote database 130 via the first access unit 142A.
本實施例的取樣顯示裝置140A還可以經由第一亮度偵測單元144A產生第一亮度補償值。第一亮度偵測單元144A設置於取樣顯示裝置140A中，其適於偵測來自第一背光模組143A的光L2並產生亮度量測值。 The sampling display device 140A of this embodiment may also generate a first brightness compensation value via the first brightness detection unit 144A. The first brightness detection unit 144A is disposed in the sampling display device 140A and is adapted to detect the light L2 from the first backlight module 143A and generate a brightness measurement value.
當第一背光模組143A以一第一亮度值驅動時，第一亮度偵測單元144A自第一背光模組143A量測一第一亮度量測值。當第一亮度量測值小於一對應至第一亮度值的第一標準亮度值時，第一處理單元145A提高第一亮度值，接著再由第一亮度偵測單元144A重新量測第一亮度量測值。第一處理單元145A重複調整第一亮度值並經第一亮度偵測單元144A量測新的第一亮度量測值，直 到第一亮度量測值等於第一標準亮度值，第一處理單元145A再將第一亮度值的變化量紀錄為第一亮度補償值，並將第一亮度補償值儲存於上傳資料。換句話說，第一處理單元145A藉由第一亮度補償值校正要提供給第一背光模組143A的第一亮度值，使第一背光模組143A所發出的光維持相同的亮度、品質。 When the first backlight module 143A is driven with a first brightness value, the first brightness detection unit 144A measures a first brightness measurement value from the first backlight module 143A. When the first brightness measurement value is less than a first standard brightness value corresponding to the first brightness value, the first processing unit 145A increases the first brightness value, and then the first brightness detection unit 144A again measures the first brightness Measured value. The first processing unit 145A repeatedly adjusts the first brightness value and measures the new first brightness measurement value through the first brightness detection unit 144A. When the first brightness measurement value is equal to the first standard brightness value, the first processing unit 145A records the change amount of the first brightness value as the first brightness compensation value, and stores the first brightness compensation value in the uploaded data. In other words, the first processing unit 145A corrects the first brightness value to be provided to the first backlight module 143A by the first brightness compensation value, so that the light emitted by the first backlight module 143A maintains the same brightness and quality.
進一步而言，當本實施例的取樣顯示裝置140A在校正第一顯示面板141A以及第一背光模組143A時，實質上是先校正第一背光模組143A再校正第一顯示面板141A。請參照圖3，其繪示了第一實施例中上述利用畫面校正裝置120A校正取樣顯示裝置140A來產生上傳資料的校正方法的流程。當取樣顯示裝置140A開始校正時，第一處理單元145A以第一亮度值驅動第一背光模組143A(步驟S11)，讓第一亮度偵測單元144A自第一背光模組143A量測第一亮度量測值(步驟S12)。自第一亮度偵測單元144A取得第一亮度量測值後，比較第一亮度量測值是否與第一標準亮度值相同(步驟S13)，其中第一標準亮度值例如為取樣顯示裝置140A在出廠時以第一亮度值驅動第一背光模組143A所測得的第一亮度量測值。 Further, when the sampling display device 140A of this embodiment is calibrating the first display panel 141A and the first backlight module 143A, it is essentially correcting the first backlight module 143A and then calibrating the first display panel 141A. Please refer to FIG. 3, which illustrates a flow chart of the method for correcting the sample display device 140A by using the screen correction device 120A to generate the uploaded data in the first embodiment. When the sampling display device 140A starts to calibrate, the first processing unit 145A drives the first backlight module 143A with the first brightness value (step S11), so that the first brightness detection unit 144A measures the first from the first backlight module 143A. Brightness measurement value (step S12). After obtaining the first brightness measurement value from the first brightness detection unit 144A, it is compared whether the first brightness measurement value is the same as the first standard brightness value (step S13), where the first standard brightness value is, for example, the sampling display device 140A at The first brightness measurement value measured by the first backlight module 143A is driven by the first brightness value at the factory.
當第一亮度量測值比第一標準亮度值低時，代表第一背光模組143A有材料耗損導致以第一亮度值驅動時的亮度比出廠時低。此時，提高第一亮度值(步驟S14)來驅動第一背光模組143A，接著再以第一亮度偵測單元144A量測並取得新的第一亮度量測值。本實施例的第一處理單元145A重複上述的步驟S12、S13以及S14直到第一亮度量測值與第一標準亮度值相同，再將這次校正時所提高的第一亮度值的數值紀錄為第一亮度補償值(步驟S15)。在得到第一亮度補償值後，接著再進行色彩的校正。 When the first brightness measurement value is lower than the first standard brightness value, it means that the first backlight module 143A has material loss and the brightness when driving with the first brightness value is lower than that at the time of shipment. At this time, the first brightness value is increased (step S14) to drive the first backlight module 143A, and then the first brightness detection unit 144A is used to measure and obtain a new first brightness measurement value. The first processing unit 145A of this embodiment repeats the above steps S12, S13, and S14 until the first brightness measurement value is the same as the first standard brightness value, and then records the value of the first brightness value improved during the correction as the first value. A brightness compensation value (step S15). After obtaining the first brightness compensation value, color correction is then performed.
請參照圖4，在本實施例中，取得第一亮度補償值後，第一顯示 面板141A顯示一測試畫面(步驟S21)，其中測試畫面包含預設要設定第一顯示面板141A的灰階值數值以及預設要設定第一背光模組143A的測試亮度值。畫面校正裝置120A會自取樣顯示裝置140A所顯示的測試畫面量測第一色彩量測值(步驟S22)，第一處理單元145A自畫面校正裝置120A取得第一色彩量測值後比較第一色彩量測值是否與第一標準色彩值相同(步驟S23)，其中第一標準色彩值例如是取樣顯示裝置在出廠時顯示測試畫面時所量測的第一色彩量測值。 Please refer to FIG. 4. In this embodiment, after obtaining the first brightness compensation value, the first display The panel 141A displays a test picture (step S21). The test picture includes a value of the gray scale value of the first display panel 141A which is preset and a test brightness value of the first backlight module 143A. The picture correction device 120A measures the first color measurement value from the test picture displayed by the sampling display device 140A (step S22). The first processing unit 145A obtains the first color measurement value from the picture correction device 120A and compares the first color. Whether the measured value is the same as the first standard color value (step S23), where the first standard color value is, for example, the first color measurement value measured when the sampling display device displays a test screen at the factory.
當第一色彩量測值與第一標準色彩值不同時，代表第一顯示面板141A的材料有耗損導或老化致透光率與出廠時不同，此時第一處理單元145A調整第一顯示面板141A(步驟S24)。本實施例的校正方法中，第一顯示面板141A的調整方式例如是調整驅動第一顯示面板141A用以施加至畫素電極的電壓強度。接著，第一處理單元145A再經畫面校正裝置120A取得新的第一色彩量測值。第一處理單元145A重複上述的步驟S22、S23以及S24直到第一色彩量測值與第一標準色彩值相同，第一處理單元145A根據這次校正第一顯示面板141A的調整數值產生第一色彩補償值。 When the first color measurement value is different from the first standard color value, it means that the material of the first display panel 141A is depleted or aged, and the light transmittance is different from that at the time of shipment. At this time, the first processing unit 145A adjusts the first display panel 141A (step S24). In the calibration method of this embodiment, the adjustment method of the first display panel 141A is, for example, adjusting the voltage intensity of the first display panel 141A that is applied to the pixel electrodes. Next, the first processing unit 145A obtains a new first color measurement value through the picture correction device 120A. The first processing unit 145A repeats the above steps S22, S23, and S24 until the first color measurement value is the same as the first standard color value. The first processing unit 145A generates a first color compensation according to the correction value of the first display panel 141A. value.
