The supporting block is fixed on the baseboard through the fixing pillar, and used for supporting and locating the liquid crystal display assemblies, and the light source assemblies are pasted on the baseboard according to the quantity and the locations of a design scheme. The LED liquid crystal display optical testing fixture provides a convenient detection platform for designers, so as to timely obtain a performance parameter of the design scheme, shorten the design cycle of novel products, and reduce the design cost.
Description
Technical field
The utility model relates to a kind of LED liquid crystal display optic test frock.
Background technology
Can only after being assembled into finished product or semi-manufacture, display device can know just by test to the evaluation of LED liquid crystal display optical property that at present the designer is that the theoretical parameter according to liquid crystal display designs fully.LED lamp as backlight, the lamp of what specification is set, what are set, where be arranged on, distance between LED lamp and the liquid crystal display etc., also all be that the designer is at the design initial stage and do not know whether design proposal meets the requirements, and does not know especially whether optical effect meets standard according to the design of the theoretical parameter of LED lamp.Only after liquid crystal display, backlight, mechanical parts etc. are assembled into semi-manufacture or finished product, learn defective and the mistake that design proposal exists by test again, the designer makes amendment again.So not only waste resource, main is to have prolonged the product design cycle, and a new product often will repeatedly recomputate through repeatedly revising, and repeatedly tissue is produced model machine, has reduced the product efficient of new product, has improved design cost.
The utility model content
Technical problem to be solved in the utility model provides a kind of LED liquid crystal display optic test frock, this LED liquid crystal display optic test frock can provide an easily detection platform for the designer, in time obtain the performance parameter of design proposal, shorten the design cycle of new product, reduce design cost.
The technical scheme that the utility model technical solution problem adopts is: this LED liquid crystal display optic test frock comprises substrate, back-up block and light source assembly, is provided with fixed orifice at described substrate; Upper surface at described back-up block is provided with baffle plate, is provided with fixed leg in the bottom of described back-up block, and described fixed leg and described fixed orifice are complementary; Bottom at described light source assembly is provided with adhesive tape.Back-up block is fixed on the substrate by fixed leg, supports the liquid crystal display assembly and to liquid crystal display assembly location, light source assembly sticks on the substrate according to quantity and the position of design proposal.This frock board design scheme is tested liquid crystal display and backlight, can in time obtain test parameter, shortens the design cycle.
For making this test fixture be applicable to the liquid crystal display of plurality of specifications size, described fixed orifice is some groups, and back-up block is fixed according to the corresponding fixed orifice of the size Selection of liquid crystal display.
Also comprise pad, pad is arranged between back-up block and the substrate, the distance between adjustable liquid crystal display screen assembly and the light source assembly, the light mixing distance of testing light source assembly.
The beneficial effects of the utility model are: this LED liquid crystal display optic test frock can the board design scheme be carried out integration test to liquid crystal display assembly, backlight, mechanical parts etc., whether the optical parametrics such as the brightness of detection liquid crystal display and backlight, colourity, uniformity coefficient are set correct, and calculate light mixing distance, magnitude setting and the layout etc. of LED lamp.Utilize this test fixture can in time obtain test data, according to data Modify rapidly design proposal, for the designer provides the practical basis of changing design proposal, the designer does not need to wait until that liquid crystal display and backlight are assembled into semi-manufacture and test, both save the time, reduced again cost.This LED liquid crystal display optic test frock can be tested for the liquid crystal display of different specification size, and is easy to use, practical, greatly shortened new product development cycle, improved new-product development speed.
Description of drawings
Fig. 1 is the structural representation of the utility model LED liquid crystal display optic test frock.
Fig. 2 is the structural representation of back-up block in the utility model LED liquid crystal display optic test frock.
Fig. 3 is the working state schematic representation of the utility model LED liquid crystal display optic test frock.
Embodiment
As shown in Figure 1 to Figure 3, this LED liquid crystal display optic test frock comprises substrate 1, back-up block 2 and light source assembly 3, at substrate 1 fixed orifice 4 is set, the bottom of back-up block 2 is provided with fixed leg 5, by back-up block 2 is fixed on the substrate 1, light source assembly 3 is fixed on the substrate 1 by adhesive tape 7.Liquid crystal display assembly 9 is placed on the back-up block 2, undertaken spacing by 6 pairs of liquid crystal display assemblies of baffle plate 9, light source assembly 3 sticks on relevant position on the substrate 1 according to the quantity in the design proposal and position, adopt this mode, if in test, need to change quantity and the position of light source assembly 3, the movement of light source assembly 3 and dismounting are all very convenient, make things convenient for the designer to determine the optimal layout mode of light source assembly 3.Liquid crystal display assembly 9 and light source assembly 3 need to just not tested after being assembled into semi-manufacture, have improved testing efficiency, shorten the new-product development cycle.
As described in Figure 1, at substrate 1 some groups of fixed orifices 4 are set, each group fixed orifice 4 by selecting different fixed orifice 4, is adjusted the distance between the back-up block 2 for a kind of liquid crystal display assembly 9 of size.When needs test Large-size LCD Screen, because center section need to arrange light source assembly 3, thus can back-up block 2 be set in the marginal position increase, to guarantee support degree.
As shown in Figure 3, between back-up block 2 and substrate 1 pad 8 is set, pad 8 is divided into some groups, comprises the identical pad of several thickness 8 in each group, and on the same group pad 8 thickness are different.Pad 8 is used for raising back-up block 2, adjusts the distance between liquid crystal display assembly 9 and the light source assembly 3, adopts this method can make faster, the more best light mixing distance of definite backlight of designer, designs mechanical fastener within the shortest time.
This LED liquid crystal display optical detection frock can be by changing quantity, the position of light source assembly 3, height with liquid crystal display assembly 9, whole structure to LED liquid crystal display optical property detects, and comprises brightness, colourity, uniformity coefficient, the light mixing distance of light source assembly 3, magnitude setting and layout etc.
