Description

TECHNICAL FIELD The present disclosure relates to the field of display devices, and in particular to a display module and a television. BACKGROUND Nowadays, in common display devices (such as televisions, computer monitors, etc.), the display module usually includes a back plate, a middle frame, a front frame, a display screen, and an optical film set. The back plate, the middle frame and the front frame together contain the display screen and the optical film set. obviously, a common display device has many parts, assembly steps are complicated, and the assembly of product is really inconvenient. US2016/187567A1 discloses a backlight module and a display device, which is used to timely remove excessive heat from the flexible circuit board and the chip and the light source to thereby reduce the operation temperatures of the electronic components and the light source and prevent the brightness of the backlight module and efficiency of the electronic components from being affected by high temperature. WO2018/166034A1 discloses a backlight module and a liquid crystal display device, which are arranged on the light source assembly and extend along the outer side of the plastic frame to the bottom of the reflective sheet, and are bonded and fixed to the glue on the plastic frame, thereby greatly increasing the heat dissipation member.
