Description of the invention α) [Technical field to which the invention belongs] The present invention relates to a method and framework for adjusting uniform display of a television wall, and particularly relates to a television wall composed of a rear projection television. [Previous technology] Press. In order to present a uniform picture quality, the video wall must first adjust the brightness and color display of each TV to a consistent setting. However, due to the aging of the components used in each TV, after the TV wall is used for a period of time, the overall quality of the daytime surface will show some uneven brightness or color. At present, the uneven display quality of the TV bridge is manually adjusted by using external measurement equipment or components to adjust the brightness and color settings. For example, the camera is placed on each TV of the TV wall to measure the parameters to obtain the brightness and color ratio parameters. Finally, from the measured parameters of all TVs, select the appropriate brightness value and color value as each Basis for TV adjustment. The aforementioned method of adjusting the TV wall mainly uses external measurement equipment or components to measure each TV to obtain relevant data parameters. However, during this measurement, it will be affected by external environmental factors, such as ambient light sources. The measured data parameters can not truly reflect the actual display status of each TV, and will also affect the subsequent uniform display adjustments made on the TV wall. In order to solve the problem that the uniform adjustment effect of the video wall is not good, the inventor of this case has devoted himself to research and cooperated with the application of science to propose a method and structure for the uniform adjustment of the video wall.

Description of the invention (2) [Summary of the invention] The main method and architecture of the present invention are illuminated by the external environment. In order to achieve uniform display on the wall, the light sensing module determines the composition of each electricity and television according to the value. In order to achieve the uniform display on the wall, each back includes the following steps: The first light field of the field; the brightness and color of each back-projection electric screen in the full dark and dark field light reflection value minus the actual bright field value of the first view can be displayed normally. In order to achieve the key objective of uniform display of the upper viewing wall, the purpose is to describe the purpose from the influence of electricity. The adjustment method is to obtain the standard value of each TV view. The adjustment method is to project the TV to all backlight sensing modes. The reflection value; the second light and the second light reflection of the interior; from the real standard values; for the stated purpose, the adjustment structure is to provide a television wall to uniformly measure the brightness and color in the interior, and to provide uniformity to the television wall. The display of the screen is always bright. According to the present invention, a projection unit is installed in the power unit to sense the reflection value of all light, and the bright field and the back can be combined. J The following steps reflect the brightness, degree, and color of the light. The video wall is a light-sensing visual presentation that obtains the back-to-back projection mode components. Each of the obtained values determines the projection power. The television value is a standard color from the aforementioned color. One is to provide several rear-projection test modules, which are fully bright and bright-field projection TVs. TVs are completely different. Obtaining rear-projection rear-projection TVs to represent each of the rear-projection TVs can be displayed in accordance with the standard display. The inverse value of each light in the electricity; a method of film and television integration; the average value of the first projection television adjustment of the shadow television in the full-dark shadow television. One embodiment of the invention is to provide an electric television wall system with several rear projection televisions. group
