Problems solved by technology
That is, when the light source 15 just starts to emit light, due to the low temperature, the rate of increase of the brightness of the backlight is lower than the design requirement.
The main reason for this situation is that the condensation of heat energy is not easy, which reduces the activity of certain elements such as mercury contained in the light source 15, thereby affecting the luminous efficiency.
especially in such Figure 1B In the shown structure, the pyrogen generated by the light source 15 due to light emission can increase the activity of the elements contained in the light source 15 and increase the luminance climbing rate. However, due to the contact between the light source 15 and the frame 20 and other components around it, the generated The heat energy is lost and cannot be condensed, which makes it difficult to increase the luminance climbing rate of the light source 15

Embodiment Construction
[0059] The invention provides a casing structure capable of increasing the luminance climbing rate of a backlight module and a backlight module using the casing structure. Taking the preferred embodiment as an example, the backlight module can be used for a liquid crystal display panel. However, in different implementations, the backlight module can also be used for computer keyboards, mobile phone keys, display panels and other devices requiring planar light sources. In addition, the present invention is preferably applied to improving the luminance of a backlight module at a low temperature. The "low temperature" referred to herein preferably refers to the condition that the external environment is lower than 0 degrees Celsius. Of course, the present invention can also be applied to other different temperature ranges.

A shell for raising the climbing rate of back light module brightness is prepared as setting the bearing base to correspond to bottom surface of light source module and its support portion to correspond to air chamber wall of light source, using said support portion to support and position light source module to form a gap between said module and said wall for making an air chamber to contain air, raising the climbing rate of brightness by decreasing direct or indirect contact of light source to bearing base to lower down heat energy loss rate caused by contact of light source to bearing base at lighting initial time.
Description
technical field [0001] The invention relates to a casing structure and a backlight module using the casing structure. Specifically, the present invention relates to a casing structure capable of increasing the luminance climbing rate of a backlight module and a backlight module using the casing structure. Background technique [0002] Backlight modules are widely used in liquid crystal display devices, computer keyboards, mobile phone keys, advertising display boards and other devices that require light sources to provide planar light sources required by such devices. Especially in recent years, the market demand for liquid crystal display devices has increased significantly. In order to meet the functional and appearance requirements of liquid crystal display devices, the design of backlight modules used in liquid crystal display devices has also become increasingly diversified. [0003] Figure 1A Shown is a conventional backlight module applied to a liquid crystal displa...
