Direct type liquid crystal TV with variable light-mixing distance

Abstract

The invention discloses a direct type liquid crystal TV with variable light-mixing distance. The direct type liquid crystal TV with variable light-mixing distance comprises a front shell for mountinga liquid crystal display; a middle shell arranged behind the front shell and connected with the front shell; a back shell arranged below the middle shell and connected with the middle shell; a mainboard and a power panel which are arranged between the middle shell and the back shell and fixed at the back of the middle shell; and a backlight source arranged in the middle shell and used for emittinglight effect, wherein the backlight source comprises a light bar arranged in the middle shell, LED lamps fixed on the light bar, lenses covered on the LED lamp, a diffusion plate arranged in the middle shell, and an optical film arranged on the diffusion plate; the lenses and the LED lamps in different shapes are arranged according to a certain regular scheme so as to form the backlight source ofthe liquid crystal TV in the mixed way, the shape structures of the middle shell and the back shell of the liquid crystal TV are synchronously adjusted according to the arrangement way of the LED lamps and the lenses, and the problem that the conventional direct liquid crystal TV is thick in complete machine, abrupt in modelling, heavy in appearance, and bad in transition section is solved.

Description

technical field [0001] The invention relates to the field of liquid crystal televisions, in particular to a direct-lit liquid crystal television with variable light mixing distance. Background technique [0002] At present, there are many structural forms of LCD TVs and continuous innovations, but the existing direct-lit LCD TV backlights all use a single LED lamp and lens, and adopt a conventional light mixing distance scheme to make the light mixing distance consistent and the thickness of the main body of the middle shell consistent. After adding the thickness of the main board, the thickness of the whole machine is thicker, which looks bulky and poor in appearance. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a direct-lit liquid crystal television with a variable light-mixing distance, which has a simple structure and saves a lot ...
