Description
Technical field
The present invention relates to a kind of liquid crystal indicator and back of the body seat thereof.
Background technology
Liquid crystal indicator is used as the display screen of general electronic products at present already widely.Recently, liquid crystal indicator combines with video technique especially and develops and LCD TV.
Yet liquid crystal indicator is no matter be to use as display screen or TV merely, and its main composition roughly is to comprise the two large divisions, the one, and liquid crystal panel, the 2nd, backlight module.
In recent years, along with the demand in market, the size of liquid crystal indicator constantly strengthens, and under this demand, the size of liquid crystal panel and backlight module also strengthens thereupon certainly.When particularly using as LCD TV, the present market demand develops toward the size more than 32 inches.
Yet when the size of liquid crystal indicator became big, backlight module became greatly thereupon, and incident problem is the increase of cost, and its main cause is that the part assembly of existing backlight module has too much waste of material.Because the backlight module size increases, then must increase its structural strength, and the reinforcement of structural strength can increase element usually or increase package program in addition, so also cause cost to increase.
It below is the shortcoming that specifies known liquid crystal indicator with Fig. 1.
As shown in Figure 1, known liquid crystal indicator mainly comprises a liquid crystal panel 18, and a backlight module.Backlight module mainly comprises a backboard 11, a plurality of light source 12, two side frames 13,14, an inside casing 15, an optical elements sets 16 and a housing 17.
The backboard 11 of known backlight module is made of metal sheet, and it does not have good intensity, and institute thinks that strengthening its structural strength then must constitute square frameworks earlier by inside casing 15 and two side frames 13,14, is aided with housing 17 again and can realizes strength demand.In addition, be generally and make inside casing 15 and housing 17 have good reinforced structure effect, industry is used a complete sheet metal (for example iron plate) mostly, the center section punching press is fallen integrally formed then inside casing 15 or housing 17 again.And therefore the center section that is stamped usually can be made material cost to descend by as consumptive material mostly.The figure number 171 that is indicated among Fig. 1 promptly is the center section 171 after housing 17 punching presses, and in other words, center section 171 promptly is for forming the consumptive material that housing 17 is caused.
From the above, for avoiding waste of material, industry also begins to utilize the framework assembling mode recently, though it can suitably avoid waste of material, because it is to be assembled by framework, so its structural strength is just not good enough a little, and what cause is to increase assembly expenses thereupon.
In addition, two side frames 13,14 of known backlight module are plastic frame body normally, itself and the backboard 11 formed EMI effects and bad that prevent! Be head it off, all must increase the metal shadowing elements in addition usually.Moreover, because backboard 11 is made of metal sheet, therefore, need organize when establishing a seat leg (not being shown among the figure) when LCD, must increase the thicker metal shell of a thickness more usually, so also make cost to descend.
Therefore, how to provide a kind of low cost, structure good, and to have the liquid crystal indicator of anti electromagnet interference function and back of the body seat thereof concurrently real be a big problem.
Summary of the invention
Because above-mentioned problem, purpose of the present invention is for providing a kind of low cost, structure good, and has the liquid crystal indicator and the back of the body seat thereof of anti electromagnet interference function concurrently.
So for reaching above-mentioned purpose, the back of the body seat of complying with the liquid crystal indicator of preferred embodiment of the present invention comprises a base board unit, first and squeezes type frame unit, reaches one second crowded type frame unit.Base board unit has a first side and a second side at least.First squeezes the first side that type frame unit is arranged at base board unit, and it has first holding part in order to the holding optical elements sets.The second crowded type frame unit is the second side that is arranged at this base board unit, and it has second holding part in order to the holding optical elements sets.
Again, the liquid crystal indicator according to preferred embodiment of the present invention comprises a back of the body seat, one the 3rd crowded type frame unit, the 4th squeezes a type frame unit and an optical elements sets.Back of the body seat comprises that one has the base board unit of a first side, a second side, one the 3rd side and a four side, one first side that is arranged at base board unit, have first of one first holding part and squeeze type frame unit, a second side that is arranged at this base board unit, have second of one second holding part and squeeze type frame unit.The 3rd crowded type frame unit is the 3rd side that is arranged at base board unit; The 4th crowded type frame unit is the four side that is arranged at base board unit; Optical elements sets is to be arranged on first holding part and second holding part.
From the above, type frame unit, second squeezes type frame unit and base board unit constitutes because of mainly squeezing by first according to liquid crystal indicator of the present invention and back of the body seat thereof, so it has well structural.Because it has had good structurally, therefore need not use inside casing, the housing element of known liquid crystal indicator again, also avoid complicated assembling process simultaneously, therefore can reduce cost greatly.In addition, type frame unit, second squeezes type frame unit and base board unit is constituted because liquid crystal indicator of the present invention and back of the body seat thereof mainly squeeze by first, so itself has been a complete metal shell, and therefore having good EMI prevents effect.In addition, because it is well structural that liquid crystal indicator of the present invention and back of the body seat thereof have, therefore, the base board unit of liquid crystal indicator and back of the body seat thereof can directly be connected with the support that adds, and need not increase the housing of any reinforcement usefulness again, so more can reduce cost greatly.
