Problems solved by technology

However, in order to generate voltages of different polarities to drive the lamps of the backlight assembly, it will cause the high voltage lines on the converter to cross each other, thus reducing the reliability of the product, and the circuit board of the converter needs to be made of high voltage Insulation treatment, resulting in higher cost
In addition, if the converter does not have high-voltage lines crossing each other, more transformers must be used to drive the lamps of the backlight assembly, which will also increase the cost of the converter

Abstract

A back light component is prepared as electric-connecting the first polarity voltage output unit to the first polarity transformer through the first connection structure and in order to output the first polarity voltage and electric-connecting the second polarity voltage unit to the second polarity transformer through the second connection structure in order to output the second polarity voltage,electric-connecting the first polarity end of lamp tube on luminous unit to the first polarity voltage output unit and electric-connecting the second polarity end of said lamp tube to the second polarity voltage output unit.

Description

Technical field [0001] The present invention relates to a backlight assembly, in particular to a backlight assembly applied to a liquid crystal display. Background technique [0002] In recent years, many flat panel display technologies have been developed. Among them, the liquid crystal display (LCD) has gradually become the mainstream of future displays because of its low power consumption, light weight and short size. Most of the liquid crystal displays are back-light type liquid crystal displays, which mainly include a front-end LCD panel and a back-end backlight assembly. Since the liquid crystal panel itself does not emit light, the light source of the panel must be provided by a backlight assembly to generate a backlight with sufficient brightness so that the light can pass through the liquid crystal layer and reach the user's eyes. [0003] The backlight assembly includes a light emitting device (for example, a lamp tube) that provides a light source and a converter that p...
