Light leakage-alleviating mobile phone backlight plate with improved light guide plate

The utility model discloses a light leakage-alleviating mobile phone backlight plate with an improved light guide plate. The light leakage-alleviating mobile phone backlight plate comprises the light guide plate; the front end of the light guide plate is provided with LED lamps; the upper parts of the light guide plate and the LED lamps are provided with a flexible circuit board; the flexible circuit board is provided with a double-sided adhesive; the front end of the light guide plate is of a trapezoid stage-shaped structure; a plurality of grooves are formed in the trapezoid stage surface of the trapezoid stage-shaped structure at intervals; the double-sided adhesive is accommodated in each groove; one surface of the double-sided adhesive linearly covers the trapezoid stage-shaped structure; and the flexible circuit board is in tight attached connection with the light guide plate; the depth of the grooves is equal to the thickness of the double-sided adhesive; and the flexible circuit board is in trapezoid stage-shaped adhesion with the light guide plate. According to the light leakage-alleviating mobile phone backlight plate, the structure of the light guide plate is changed, so that the light guide plate can be maintained level with the LEDs, and therefore, light leakage phenomena can be avoided, and the adhesion of the flexible circuit board and the light guide plate can be maintained.
