Abstract: An exemplary liquid crystal display (LCD) (40) includes an LCD panel (42), a backlight module (41), and a housing assembly. The housing assembly includes a rear housing (48) and a corresponding front housing (46) to secure the LCD panel and the backlight module. The rear housing has a first sidewall (481) with a first hole (482). The front housing has a second sidewall (461) with a second hole (462) aligned with the first hole. A flexible printed circuit board (44) is electrically connected to the LCD and passes through the first and second holes, such that the housing assembly can protect the flexible printed circuit board without reducing the mechanical strength of the housing assembly.

Abstract: An exemplary backlight module (12) includes a light guide plate (14) and a frame (16) receiving the light guide plate. The frame includes a first side wall (160), and a second side wall (167) connected with the first side wall. The frame further defines a first sliding guide (165). The first side wall defines an opening (163) therein. The opening is configured for allowing the light guide plate to be inserted into the frame therethrough. The first sliding guide is defined at an inner side of a portion of the frame that is adjacent to the second side wall, and supports one side of the light guide plate. The first sliding guide communicates with the opening, and is configured for allowing the light guide plate to slide into the frame.

Abstract: An exemplary display device (2) includes a display system configured for displaying images and an optical lens system (23) adjacent to the display system. The optical lens system includes a first lens unit (231) having a first optical correction rate in a first correction axis and a second lens unit (233) adjacent to the first lens unit. The second lens unit has a second optical correction rate in a second correction axis that is different from the first correction axis.

Abstract: An exemplary double-layer lamp (210) includes an inner cold cathode fluorescent lamp (CCFL) (211), an outer glass tube (212) accommodating the inner CCFL therein, and a reflecting member (214) disposed between the inner CCFL and the outer glass tube. An exemplary backlight module (200) applies the above double-layer lamp. The backlight module has a smaller volume.

Abstract: An exemplary in-vehicle LCD device (100) includes a temperature sensor (101), a power circuit selector (102), a power circuit (103), a reverse power circuit (105), a Peltier member (106), and a LCD module (107) having the Peltier member operatively coupled thereto. The temperature sensor, the power circuit selector, the power circuit, the Peltier member, and the LCD module are electrically connected series, and the reverse power circuit is electrically connected between the power circuit selector and the Peltier member. The in-vehicle LCD device can automatically control the Peltier member to be in either one of the normal and reverse operation states or be turned off, according to the environmental temperature detected by the temperature sensor. Therefore the operational temperature of the LCD module can be adjusted to be in the normal range.

Abstract: A backlight module (30) has a light guide plate (300) and a light source (320) opposite to the light guide plate. The light guide plate has a first light incident surface (306), a second light incident surface (308) adjacent the first light incident surface, and a groove (303) drilling through the first and second light incident surfaces at an intersection of the first and second light incident surfaces. A bent region of the light source is accommodated in the groove.
