Detailed Description
The present utility model is further illustrated by the following examples, but the present utility model is not limited to these examples.
The light leakage preventing LCM module mainly comprises a black backlight rubber frame 1, liquid crystal glass 3, a backlight FPC 5, an LCD-FPC 6 and an LCD 7; the liquid crystal glass 3 and the black backlight rubber frame 1 are arranged from top to bottom, and the liquid crystal glass 3 and the black backlight rubber frame 1 are tightly assembled; the LCD-FPC 6 and the LCD 7 are arranged between the liquid crystal glass 3 and the black backlight rubber frame 1 and are arranged on the upper side of the black backlight rubber frame 1; the backlight FPC 5 is arranged on the lower side of the black backlight rubber frame 1; the backlight FPC 5, the LCD-FPC 6 and the LCD 7 are electrically connected; the liquid crystal glass 3 completely covers the display area of the LCD 7. The backlight FPC 5, the LCD-FPC 6 and the LCD 7 work together to realize the display content when the screen is on. A cross-sectional view of a top view of the present utility model is shown in fig. 1. For the convenience of marking and viewing, the structure diagram with the same size as that of fig. 1 is left-hand-viewed, and then is transversely enlarged by 4 times and longitudinally enlarged by 1.5 times, so that a left-hand view as shown in fig. 2 is obtained.
The backlight plastic frame of the existing LCM module is white, and when the back is bright, light leakage occurs between the backlight plastic frame and the liquid crystal glass 3. The utility model sets the black backlight rubber frame 1 to replace the original white backlight rubber frame, the black backlight rubber frame 1 has stronger light absorption effect compared with the white backlight rubber frame, and the utility model also tightly assembles the black backlight rubber frame 1 and the liquid crystal glass 3, and more effectively avoids the light leakage of the gap between the black backlight rubber frame 1 and the liquid crystal glass 3, so that the light leakage situation can not occur even if the front cover or the rear cover of the LCM module is made of semitransparent or transparent materials.
Further, the LCM module further comprises a rear cover, wherein the rear cover is arranged at the lower side of the black backlight plastic frame 1; the black backlight rubber frame 1 is fixed on the rear cover; the black backlight plastic frame 1 completely covers the rear cover frame-defined area. The black backlight rubber frame 1 is fixed with the rear cover and covers the locking area of the rear cover, so that light leakage of the whole rear cover cannot occur due to the problem of material color.
Further, the LCM module further comprises a front cover, wherein the front cover is mounted in a fit manner with the rear cover; the black backlight rubber frame 1 is fixed at the joint between the front cover and the rear cover. The black backlight rubber frame 1 is fixed at the joint between the front cover and the rear cover and completely covers the area framed by the front cover and the rear cover, so that light leakage can not occur to the whole front cover and the whole rear cover due to the problem of material color.
