Abstract: A backlight module comprises a back frame, a light guide plate disposed in the back frame, and elastic corner parts for locating the light guide plate. The elastic corner parts are disposed at diagonal corners of the backlight module and sandwiched between the back frame and the light guide plate. The elastic corner parts can locate the light guide plate in the back frame, and the desirable cushioning performance and appropriate hardness of the elastic corner parts provide a desirable space for thermal expansion and contraction of the light guide plate. Meanwhile, the elastic corner part corresponding to the light incident side is greater than that of the non-light-incident sides for ensuring the light mixing distance between the LEDs and the light incident side of the light guide plate, which can improve the light unitization factor of the LEDs and save both the product cost and the mold cost.

Abstract: The present invention discloses a back light module and a liquid crystal display (LCD) thereof. The back light module comprises a light guide plate, an optical sheet laid on the light transmission surface of the light guide plate, wherein the edge of the optical sheet is fixed to the light guide plate by a plurality of positioning structures. With application of the positioning structures, because the expansion coefficient of the optical sheet is not nearly to that of the frame but is close to the thermal expansion rate of the light guide plate, after the optical sheet is fixed to the light guide plate, the light guide plate is expanded along with the expansion of the optical sheet when subject to heating, and shrunk along with the shrinking of the optical sheet when the temperature drops. Thus, the optical sheet is not easy to warp due to the minimum performance change of the optical sheet and the light guide plate, and the temperature environment is also very similar because the optical sheet is near to the light guide plate. Therefore, as compared with the frame, the temperature of the optical sheet is more similar to that of the light guide plate, and the thermal expansion rate of the optical sheet is also similar to that of the light guide plate. Thereby, the warping of the optical sheet is further decreased.

Abstract translation: 本发明公开了背光模块及其液晶显示器（LCD）。 背光模块包括导光板，布置在导光板的透光表面上的光学片，其中光学片的边缘通过多个定位结构固定到导光板。 通过应用定位结构，由于光学片的膨胀系数与框架的膨胀系数几乎不接近导光板的热膨胀率，所以在将光学片固定到导光板之后， 导光板随着加热时的光学片的膨胀而膨胀，随着温度下降，随着光学片的收缩而收缩。 因此，由于光学片和导光板的最小性能变化，光学片不容易翘曲，并且由于光学片靠近导光板，所以温度环境也非常相似。 因此，与框架相比，光学片的温度与导光板的温度更相似，并且光学片的热膨胀率也与导光板的热膨胀率相似。 由此，光学片的翘曲进一步降低。

Abstract: An object of the present invention is to eliminate COG irregularities around a display area caused by distortion of a glass substrate generated when IC chips are connected by a COG method in a liquid crystal display device. A liquid crystal display panel configured using an opposed substrate and a TFT substrate and a backlight are accommodated using an upper frame and a lower frame. IC chips are connected to an end portion of the TFT substrate of the liquid crystal display panel via ACFs by the COG method. Protrusions formed at the upper frame are in contact with the both sides of each IC chip, and the distortion of the TFT substrate generated by the COG method is eliminated by the protrusions. The TFT substrate can be flattened by eliminating the distortion, and the COG irregularities around the display area can be suppressed.
