Shockproof and high temperature resistant device and method for target device, backlight module, and display device

Abstract

The invention provides a vibration and high-temperature preventing device and a vibration and high-temperature preventing method for a target device, a backlight module and a display device. The vibration and high-temperature preventing device for the target device comprises extension and retraction mechanisms and extension and retraction mechanism control modules. An end of each extension and retraction mechanism is fixed onto a fixing component at the peripheral edge of the target device, and gaps between the target device and the fixing component at the peripheral edge of the target device can be filled with the extension and retraction mechanisms in extension states and can be reserved by the extension and retraction mechanisms in retraction states; the extension and retraction mechanisms can be extended under the control of the extension and retraction mechanism driving modules in first states so that the gaps between the target device and the fixing component at the peripheral edge of the target device can be filled with the extension and contraction mechanisms, and the target device can be supported and can be prevented from vibrating; the extension and retraction mechanisms can be retracted under the control of the extension and retraction mechanism control modules in second states, so that the gaps between the target device and the fixing components at the peripheral edge of the target device can be reserved. The vibration and high-temperature preventing device, the vibration and high-temperature preventing method, the backlight module and the display device have the advantage that vibration or high temperatures can be prevented.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shockproof and high temperature resistant device and method for a target device, a backlight module, and a display device. Background technique [0002] With the development of high technology, display technology has completely entered people's lives. While the society is progressing, the display field is also pursuing a wider development space. In the face of diverse living environments, the survivability of display devices has gradually come into people's sight, such as the impact of harsh environments (high and low temperature, high humidity, high speed, etc.) on display devices. [0003] In the existing liquid crystal module, due to consideration of thermal expansion of the light guide plate, a certain gap is reserved between the light guide plate and the plastic frame when assembling the module. However, the existence of the gap easily leads to misalignment of the light ...

Problems solved by technology

However, the existence of the gap easily leads to misalignment of the light guide plate and the light bar during assembly, transportation and high-temperature testing, resulting in scratches on other film materials or uneven brightness of the backplane.
