The light to be measured is taken to adjust the color of the screen. Referring to Fig. 3, there is shown a color correction flow of a screen color correction system to which an embodiment of the present invention is applied. First, set the original white point of the display so that it is as close as possible to the desired target "white point" (S1). Next, different white luminance values are set, and the gray balance calibration is used to correct to the target value (S2). Further, the lowest black luminance value is set so that it is pure black as the comparison minimum standard value (S3). Next, set the color RGB (red, green, and blue) value, the difference between the target color value and the current color value, represented by Delta ab. A gap of zero indicates that the display has been accurately adjusted to the desired white point. If the difference is less than 0.5, it indicates that the setting of the display is close enough to the target value (S4). Finally, the brightness and color linear curves are fine-tuned, and the color samples displayed on the display gradually change from black to white. The display output brightness of each sample is measured. A comparison table (S5) between the input RGB (red, green, and blue) and the output luminance value will be drawn.

Table 1 is a table of standard color coordinates. From the reference, in the color accuracy test, the Delta E parameter is used to measure the degree of entry and exit of the display with the standard color. The smaller the number, the closer it is to the standard color. The left side of the table is the standard color definition value, and the right side is the real test value. This table only shows that the goal of using the correction method is to correct the value of Delta E to the minimum. If the color of the screen is regarded as the transmitting end, then the NB front lens will be output as a receiving end, and the screen will output different colors. Color or brightness patterns that are processed by the program and have a predetermined standard value. The received part is subtracted from the measured value of the screen, converted to the delta value, and then the delta value is used to compensate the setting of the screen, and the delta is measured to the minimum.

Referring to FIG. 4, in an embodiment of the present invention, the screen color correction system of the embodiment of the present invention can be used to correct the screen due to the user escaping from the factory color or the screen aging due to long-term use of the screen. As shown in the figure, the three color deviations of A, B, and C can be corrected back to the target value.

According to the screen color correction system of the embodiment of the invention, the low-cost light guiding unit can be used together with the original image capturing unit of the electronic device to correct the color of the screen. Compared to conventional high cost professional color correction devices, the present invention provides a solution that is inexpensive and generally acceptable to consumers.
