Description

White balance device for display

The invention relates to a white balance device for a display, in particular to a white or gray light-transmissive sheet and a color temperature sensing element on a display such as a television, a computer monitor, a tablet computer, a camera, a video camera, a projector and a mobile phone. The balance device can directly obtain the ambient color temperature value of the external light, and the white color balance calculation process is performed by the main processor (CPU) on the television, the computer monitor, the tablet computer, the camera, the camera and the mobile phone. In order to get accurate white balance value on site, instantly adjust the color temperature of the display or display the accurate color temperature value of the display for manual adjustment of the color temperature of the display to match the instantaneous color temperature of the scene, and the eye can see the correct color of the picture or film produced by the display. The white balance device design of the display.

Press, the display has a receiving color temperature value and can manually or automatically adjust the color temperature value of the display according to the external signal value to conform to the field color temperature value, and the human eye has an automatic color temperature adjustment function, and the display cannot automatically adjust its own color temperature value. When it comes to the human eye vision, it sees the incorrect display color. The eye feels a visual difference and feels that the display color is strange and unnatural. It can be used to display the color temperature value of the scene in the window, and then manually. Adjusting the color temperature of the display screen or the automatic control circuit to adjust the color temperature of the display screen. The display has the characteristics of receiving the color temperature value, and the color temperature value can be manually and automatically adjusted. The characteristics of the present invention are all in the scope of the present invention, and the average person may misunderstand each The factory color setting of the display of an electrical appliance is not correct Indeed, the quality of the brand's electrical display screens is misunderstood.

The display has a fixed color temperature value for its display function, for example, 6500K is used as the factory preset value, and each display use work has different ambient color temperature values in different time, when the field light source color temperature value is projected to the display When it affects the color temperature value of the display or raises or lowers the color temperature value of the screen surface, the eye pressure of the sensitive color sensation of the human eye changes, causing the display to display an incorrect color. The color of the display is for the average person. It is an extremely difficult adjustment work, and the indoor color temperature often changes frequently due to different mixed light sources indoors and outdoors, making this coloring work more difficult and almost infeasible. In the dark, the display can be protected from ambient light sources. And see the correct color that the display can show.

At present, there is no display with automatic white balance design, even the display screen of the camera and the camera are the same, and the sunlight color temperature of the outdoor light source changes continuously during the day, if the current color temperature is used by an advanced camera. Adjust the function for experiment. Generally, the camera has the function of 100K per button adjustment. The camera monitor is set in advance so that the monitor with manual white balance can roughly match the color of the indoor environment object, and then adjust the color temperature to manual. The color temperature adjustment function, and the color adjustment by the manual function, can be found that it is basically impossible to call out the correct color temperature obtained by the manual white balance. This simple experiment can show that the average person should adjust the display to the correct color temperature at that time. One thing that is difficult and impossible, let alone the color change and the eye feeling caused by the change in color temperature caused by the continuous change of the ambient color temperature.

The present inventors have in view of the above-mentioned conventional display that the display has to adjust its correct color temperature at that time. Difficult to be improved, I hope to provide a breakthrough design to enhance practical effects, but to concentrate on research and design, and to integrate the professional technical knowledge and practical experience and research design of related product design and sales for many years. As a result of the obtained, a white balance device of a display of the present invention was finally developed to provide a user.
