Problems solved by technology
[0014] First, there are cases where some users who use the monitor do not know that there is an AD converter adjustment function on the menu
[0015] Second, the best white balance adjustment cannot exist until the user runs the ADC function
[0016] 3. Due to the adjustment of the analog-to-digital converter to use the signal of the personal computer, it does not solve the noise in the image signal of the video card
[0017] That is, the analog-to-digital converter function is operated not only for the image signal input from the personal computer, but also for noise or other unnecessary signals included in the image signal input, and therefore, there is a possibility of expressing the screen by undesired color sense

Embodiment Construction
[0034] Embodiments of the display signal adjustment device and method of the present invention will be described in detail below with reference to the accompanying drawings.
[0035] First, if image 3 As shown, the display signal adjustment device of the present invention includes: a signal input part 21 receiving the image signal input by the above-mentioned video card 10, and outputting an analog-to-digital conversion corresponding to the signal level input by the above-mentioned signal input part 21 to the above-mentioned analog-to-digital converter 24. The scaler 23 of the device adjustment mode senses the signal level input through the above-mentioned signal input part 21, and according to the above-mentioned sensed signal level, the analog-to-digital converter adjustment mode output by the above-mentioned scaler 23 shall prevail, so that it can adjust White balance is controlled by the control unit 22 of the above-mentioned analog-to-digital converter 24 .

The invention relates to display signal adjust device and method to show optimal white balance in user environment. Wherein, the method comprises: sensing output signal level when inputting image signal to said PC; outputting adjust mode of A / D converter opposite to said signal level; with said adjust mode as standard, running A / D converter adjustment. Thereby, even user is unaware of the adjust function, it can also automatic run the function to improve convenience. It can also use the adjust mode not generated by PC signal to run the adjustment for A / D converter, avoids effect of PC noise, and improves reliability of product.
Description
technical field [0001] The present invention relates to a display, in particular to a display signal adjustment device and method that embodies optimal white balance (White Balance) in a user environment. Background technique [0002] Generally speaking, image instruments such as monitors have different sizes of personal computer signals input from the outside. When the monitor finally outputs, the peak white level (PeakWhite) of each signal can only be different. [0003] Therefore, it is necessary to adjust the analog-to-digital converter (analog / digital conversion unit) inside the monitor so that the signal input from the personal computer can reflect the optimum white balance. [0004] The above-mentioned AD converter adjustment function is added to the OSD (On Screen Display), so that users can use it when necessary. [0005] A prior art display signal adjustment method will be described below. [0006] First, if figure 1 As shown in , the monitor receives an image s...
