Embodiment Construction

[0023] The back of the flat-panel TV generally has screw holes for mounting and fixing the wall-mounted device, see the attached image 3 shown. We design a fixture device as attached Figure 4 As shown, the flat-panel TV can be fixed on the wall.

[0024] The main part of the device includes parts such as support, base and wall hanging.

[0025] as attached Figure 5 As shown, there are four wall hanging rods, two of which are arranged horizontally and vertically, and they are fixed through a plurality of fixing holes 14 to form a rectangular arrangement. The position of each fixing hole 14 and image 3 The fixing hole positions of the fixing screw holes 5 on the TV back panel are related. The fixing holes on each wall hanging rod are evenly distributed in the form of round holes, and the screws are connected to the back panel of the TV through the round holes. Changing the fixed position can adjust the rectangular size of the wall hanging rod, and can fix measurement p...

Abstract

The invention relates to an apparatus for measuring a vertical visibility angle of a flat-panel television set. The apparatus comprises a testing platform for a vertical visibility angle of a flat-panel television set; the testing platform is provided with a rotating plate for supporting the flat-panel television set, a light-split type luminance meter, and a tripod capable of being adjusted up and down. The light-split type luminance meter is arranged on the tripod being adjusted up and down and the distance L between the light-split type luminance meter and the central shaft of the rotating plate is three times to four times as long as the height of a screen of a flat-panel television set. A tested flat-panel television set is arranged on the rotating plate. Besides, a Chinese-character-"jing"-shaped support is installed on the central shaft of the rotating plate; mounting holes are formed in a support body forming the Chinese-character-"jing"-shaped support, wherein the mounting holes are ones for horizontal or vertical mounting of the back side of the flat-panel television set.

Description

[0001] 1. Technical field [0002] The invention relates to a test method for a display performance of a flat-panel TV, which is a realization method for testing the vertical viewing angle of the flat-panel TV. [0003] 2. Background technology [0004] As an important indicator for evaluating the optical display performance of flat-panel TVs, the viewing angle of LCD TVs has attracted more and more attention. The viewing angle includes two indicators, the horizontal viewing angle and the vertical viewing angle. The size of the vertical viewing angle is one of the most important indicators to measure the display performance of a flat-panel TV, so how to measure this indicator correctly and easily is very important. [0005] According to relevant standards (such as: SJ / T 11348 digital TV flat-panel display test method), the position of the luminance meter is required to be aligned with the center of the screen, and the position of the luminance meter should be able to carry out...
