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] The embodiments of the present invention will be described in detail below with reference to the drawings. The present invention is not limited to the embodiments described below. Those skilled in the art can perform operations such as addition, limitation, deletion, and addition to the constituent elements of the present invention without departing from the scope of the technical idea of ​​the present invention.

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

[0030] Such as figure 1 As shown, the direct type liquid crystal display device is composed of the following parts: a plurality of pixels are formed in a matrix type (matrix type) between the lower substrate and the black matrix to form an RGB (red, green, and blue) color filter between the upper substrate and the liquid crystal bonded together. Panel 105; a guide surface 103 for fixing the liquid crystal panel 105; a plurality of lam...

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 the unbalance of lamp current. Background technique [0002] Recently, the rapidly developing liquid crystal display devices tend to be miniaturized and thinner, and products with more powerful performance have been launched one after another. So far, CRT (cathode ray tube: cathode ray tube), which is 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, because of its advantages of miniaturization, lightness and thinness, and low power consumption, liquid crystal display devices have attracted much attention as a substitute for overcoming the shortcomings of CRTs, and even now almost all information processing instruments that require display devices are equipped The extent of the liquid crystal display device. [0004] Such a liquid crystal display ...
