Problems solved by technology

There will be no problem when 2 lamps are combined with the lamp holder, but if 3 lamps are used as a set, when combined with the lamp holder, there will be a problem of uneven current on each lamp
[0013] Therefore, the output load of the inverter is biased toward one lamp, whereby losses due to overloading of the inverter components may occur
[0014] In addition, due to the unevenness of this current, there may also be a problem of uneven brightness of the liquid crystal display device as a whole.

Embodiment Construction

[0028] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The present invention is not limited to the embodiments described below, and those skilled in the art can add, limit, delete, increase and other operations on the constituent elements of the present invention within the scope of not departing from the technical idea of ​​the present invention.

[0029] FIG. 1 is an exploded perspective view of a direct-type liquid crystal display device of the present invention.

[0030] As shown in FIG. 1, a direct-type liquid crystal display device is composed of the following parts: a lower substrate in which a plurality of pixels are formed in a matrix type and an upper substrate in which RGB (red, green and blue) color filters are formed between black matrices are bonded to the substrate. A liquid crystal panel 105 together; a guide surface 103 for fixing the above-mentioned liquid crystal panel 105; a plurality of la...

Abstract

A liquid crystal display equipment comprises the following parts: a LCD panel; a directing surface for fixing the LCD panel; a lower casing assembled with the directing surface; a optical cardinal plate and a diffusing plate stacked content in the lower area of the LCD panel in sequence; lamps arranged at the inside of the lower casing in stated intervals; a lamp bracket for uniting the lamps in a suit; a baffle-board reflecting much light to the diffusing plate and enclosing the lamps for limiting the light loss in maximum; and a ITO film membrane for prevent the current of the lamps from revealing when through the baffle-board. The invention has the advantages of: the current characteristics of many lamps revealing is averaged, the imbalance of the current is improved, the effect of the inverter exploiting is easily achieved.

Description

technical field [0001] The present invention relates to a liquid crystal display device for improving lamp current unbalance. Background technique [0002] Recently, rapidly developing liquid crystal display devices tend to be miniaturized and thinned, and products with more powerful performances have been launched one after another. A CRT (cathode ray tube: cathode ray tube) which has been widely used in display devices has many advantages in terms of performance and price, but has many disadvantages in terms of miniaturization and portability. [0003] On the contrary, liquid crystal display devices have attracted much attention as a substitute that can overcome the shortcomings of CRT due to their advantages such as miniaturization, lightness, and low power consumption. Even now, almost all information processing instruments that require display devices are configured The extent of the liquid crystal display device. [0004] Such a liquid crystal display device generall...
