Embodiment 1

[0077] The invention discloses a standard prototype screening method for flat-panel TV energy efficiency comparison test, which is used to screen out three flat-panel TV sets of the same type from a batch of flat-panel TVs of the same model for comparison testing of flat-panel TV energy efficiency. A standard prototype, including:

[0078] Step S1. From a batch of flat-panel TVs of the same model, select a flat-panel TV that meets the design standards of the TV set for pretreatment, so that the temperature and humidity of the components of the flat-panel TV can be stabilized, and will be The processed flat-panel TV is used as the primary prototype;

[0079] Among them, the design standards of flat-panel TVs include: display screen type (for example: liquid crystal, plasma), display screen size (for example: 50 inches, 65 inches, etc.), display screen resolution (for example: high-definition, 4K, etc.) , Voltage parameters (for example: 100V, 220V, etc., generally require an e...

Embodiment 3

[0133] On the basis of the above-mentioned embodiment one or embodiment two, the present embodiment three also adopts the following preferred implementation modes:

[0134] The standard prototype screening method also includes:

[0135] Step S4, if the three standard prototypes cannot be selected in the step S3, another batch of flat-panel TVs of the same model is selected, and the steps S1 to S3 are repeated until the three standard prototypes are selected .

Abstract

The invention discloses a method for screening standard prototypes of flat-panel TV energy efficiency comparison tests. Firstly, through step S2, under the working conditions specified in step S2-1 to step S2-3, from a batch of flat-panel TVs of the same model Three flat-panel TVs with uniform energy efficiency are screened in the machine, that is, three re-selected prototypes; and then through step S3, the change of the environmental climate is simulated to judge whether the energy efficiency of the three re-selected prototypes is improved after the environmental climate changes. Still can keep stable, obtain three flat-panel TVs with uniformity and stable energy efficiency with final screening, namely can be used for three standard prototypes of flat-panel TV energy efficiency comparison test; Make: the screened out of the present invention The three standard prototypes can fully comply with the parameter requirements for standard prototypes in the "IEC 62087 Standard", and have high accuracy, stability and reliability. base.

Description

technical field [0001] The invention relates to a standard prototype screening method for flat-panel TV energy efficiency comparison test. Background technique [0002] The energy efficiency of flat-panel TVs in China, the United States, and the European Union are all mandatory, so it is necessary to accurately label the energy efficiency information of each flat-panel TV. [0003] At present, flat-panel TV manufacturers around the world continue to use the concept of confirmation inspection, and conduct random inspections of energy efficiency from each batch-produced flat-panel TV according to a certain sampling principle. But no matter how strict the sampling inspection is, it is impossible to carry out 100% energy efficiency routine inspection, because the traditional flat-panel TV energy efficiency test scheme takes a long time, the operation is complicated, and there are many interference factors. Manufacturers of flat-panel TVs do not have complete confidence in the e...
