Abstract

An embodiment of the invention provides a backlight display screen and a mobile terminal. The backlight display screen comprises a driving integrated circuit, a backlight source, a flexible circuit board and a heat dissipation membrane; the backlight source is arranged under the driving integrated circuit; the flexible circuit board is electrically connected with the driving integrated circuit, the flexible circuit board is bent into a U shape and includes a first part laid on one side of the backlight source toward the driving integrated circuit, a second part bent into an arc and a third part laid on the side of the backlight source away from the driving integrated circuit, and the second part is arranged between the first part and the third part; the heat dissipation membrane comprisesa first heat dissipation part which is affixed to the side of the driving integrated circuit away from the backlight source and a second heat dissipation part which is affixed to the external surfaceof the flexible circuit board. By the arrangement, the heat dissipation membrane is fitted on the side of the backlight source of the driving integrated circuit and the outer surface of the flexible circuit board, the heat dissipation area is enlarged, and heat dissipation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a backlight display screen and a mobile terminal. Background technique [0002] At present, the most commonly used display screen in the mobile terminal (such as mobile phone, tablet computer) industry is a TFT (Thin Film Transistor, thin film transistor) display screen, which is a kind of LCD (Liquid Crystal Display, liquid crystal display). TFT display screen is different from Amoled (Active-matrix organic light emitting diode, active-matrix organic light emitting diode panel) screen self-illumination, which mainly relies on backlight to provide light source for it. The backlight is essentially a string of LED (Light Emitting Diode, light emitting diode) lights, so the backlight is the main heat source of the display screen. Another heat source of the display screen is its driver IC (Integrated Circuit, integrated circuit). Due to the spatial structure, the projection o...
