Embodiment

The utility model is described in detail with reference to the accompanying drawings and examples.

As Figure 1-4, a kind of display module, including the backlight 2 with underframe 21 and it is arranged on the backlight 2 Exiting surface on display panel 1, be arranged with upper ledge frame 3 outside the backlight 2 and display panel 1；The top surface of the upper framework 3 With vision area opening.

The display panel 1 includes upper substrate 11 and infrabasal plate 12, is provided between the upper substrate 11 and infrabasal plate 12 Liquid crystal material layer；Upper polaroid 13 is provided with the one side of the upper substrate 11 away from infrabasal plate 12, the infrabasal plate 12 is remote Down polaroid 14 is provided with the one side of upper substrate 11；Being bound in the one side of the infrabasal plate 12 away from down polaroid 14 has at least One driving IC 15；The infrabasal plate 12 is provided with fin 4 in the one side away from least one driving IC 15.

The backlight 2 includes underframe 21, the light guide plate 22 being arranged in the underframe 21 and is arranged on described lead The lamp bar of the incidence surface of tabula rasa 22；An at least optical film 23 is provided with the exiting surface of the light guide plate 22, typically includes expanding successively Dissipate film, lower bright enhancement film and upper bright enhancement film；The one side of the light guide plate 22 away from exiting surface is provided with reflector plate 24；The underframe Anti-dazzling screen is provided with 21 top surface, the anti-dazzling screen is two-sided to be respectively provided with viscosity, for pasting the fixed backlight 2 and display Panel 1.
