Embodiment Construction

[0038] Such as figure 1 The methods for the reliability test of the flat-panel TV shown include the reliability test of the TV core board and the reliability test of the whole machine. The reliability test of the core board includes:

[0039] Temperature stress test:

[0040] a. The core board of the flat-panel TV is placed separately in the strengthened test bench to carry out the low-temperature step stress test. Extend the connection line between it and the power board, remote control board, screen and other components. The length of the connection line is 1.2 meters to 1.5 meters to increase the attenuation stress of the DC voltage and the signal on the screen.

[0041] Starting from 0°C, the temperature gradually decreases to -40°C. The test temperature points are 0°C, -20°C, -32°C, -35°C and -40°C in chronological order, and each test temperature point lasts for 10 minutes. The core board is subjected to temperature stress test;

[0042] b. Place the core board of the...

Abstract

The invention relates to a flat panel television reliability test method. The method comprises the following steps: (a) carrying out stepping decrease on a temperature to 40 DEG C below zero, and testing a core plate at each temperature point; (b) carrying out stepping increase on the temperature to 80 DEG C, and testing the core plate at each temperature point; (c) testing the core plate in a cycle of 30 DEG C below zero and 80 DEG C; (d) carrying out 4 Grms to 40 Grms vibration stepping increase, and testing the core plate at each vibration point; (e) testing the core plate in the cycle of 30 DEG C below zero and 80 DEG C, and carrying out 6 Grms to 28 Grms vibration stepping increase test on the core plate simultaneously; (f) testing a whole machine at 40 DEG C to 65 DEG C; (g) testing the whole machine at 0 DEG C to 32 DEG C; (h) testing the whole machine at 0.1 Grms to 0.5 Grms; wherein in steps of (a) to (h), alternating current electric stress of 100V/47Hz and 240V/63 Hz are applied to a test product alternatively. According to the method, problems of low efficiency and high cost in a traditional reliability test can be effectively solved, and a reliability level of the product can be raised obviously and greatly.

Description

technical field [0001] The invention relates to a testing method, in particular to a reliability testing method of a flat panel TV. Background technique [0002] The home appliance industry has the characteristics of short R&D cycle and fierce market competition, and usually requires a high level of product reliability, so there are many difficulties in the work of reliability testing. The traditional flat-panel TV reliability test only uses the reliability test technology of simulating the authenticity of the environment for components such as the TV core board, as an important means of analyzing and evaluating the reliability level of the product. Due to the long reliability test cycle, high cost, and difficult implementation, the products that have passed the reliability test will still have many defects, and it is becoming more and more difficult to meet the needs of the rapid development of today's electronic product industry. Contents of the invention [0003] In vi...
