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, then 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 standard prototype screening method for a flat-panel television energy efficiency comparison test, and the method comprises the steps: firstly obtaining three flat-panel televisions with uniform energy efficiency through screening from a batch of flat-panel televisions of the same model under the working conditions specified in the steps S2-1 to S2-3, i.e., three reselection prototypes; step S3 is carried out, simulating the change of the environmental climate to judge whether the energy efficiency of the three reselection sample machines can still keep stable or notafter the environmental climate changes, and finally screening to obtain three flat-panel televisions with uniformity and stable energy efficiency, namely three standard sample machines which can be used for comparing and testing the energy efficiency of the flat-panel televisions; therefore, the three screened standard prototypes can completely meet the parameter requirements for the standard prototypes in the IEC 62087 standard, the accuracy, the stability and the reliability are high, and a foundation is provided for forming a unified flat-panel television energy efficiency comparison teststandard in the flat-panel television industry.

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...
