Description

[Modification and Replacement Page 6 of January 24, 2014] [Technical Field] [0001] The present invention provides a light source system that can be used as a backlight module of a display device, especially a module including a brightening device Light source system. [Prior Art] [0002] A liquid crystal display device has been widely used in a personal desktop computer screen because of its slimness, low power consumption, and no Korean pollution. And portable information products such as notebook computers, personal digital assistants (PDAs), mobile phones, etc., and gradually replaced cathode ray tube (CRT) monitors and traditional television. _3] In general, a liquid crystal display module (LCM) is the most critical device in a liquid crystal display, and includes components such as a liquid crystal display panel and a backlight module. The liquid crystal display panel is provided with a liquid crystal molecular layer in two glass substrates, and an alignment layer is usually applied on each of the glass substrates so that the liquid crystal molecules are aligned along a specific direction parallel to the glass surface. By using an electronic component such as a transistor or an electrode on a glass substrate, an electric field can be supplied to the liquid crystal molecules to cause the liquid crystal molecules to rotate according to the magnitude of the electric field. Since the birefringence of the liquid crystal molecules changes with the direction of the liquid crystal molecules, The polarized light changes in the direction of the polarization when passing through the liquid crystal molecules. Therefore, the display principle of the liquid crystal display panel is that a polarizer is disposed on each of the upper and lower sides of the liquid crystal display panel, and the rotation of the liquid crystal molecules is used to control the amount of light on the light surface, and the screen can be displayed. 0004] Please refer to the first circle. The first figure shows the display principle of the conventional liquid crystal display panel. Form A0101 Page 3 1/35 Page 1003026372-0 1342451 The revised replacement page is shown on January 24, 100. The conventional liquid crystal display panel includes two glass substrates 1 2 2 0 on which electrodes are disposed, and liquid crystal molecules 1440 are disposed in the middle of the glass substrate 1 220. The two sides of the glass substrate 1 22 0 are provided with two first and second polarizers 1660, 1880 which are perpendicular to each other. Therefore, in the case where no electric field is applied in the above figure, the natural light generated by the light source passes through the first polarizer. At 1660, the linearly polarized light P having only the first polarization component is formed, and passes through the glass substrate 1 220 and the liquid crystal molecular layer. It is worth noting that in a liquid crystal molecular layer of a suitable thickness, the liquid crystal molecules 1440 will cause the polarization direction of the line-polarized light P to change just 90 degrees to form a second polarization component-line polarized light S. Second polarizer 1 880. The other side; when the voltage is applied to the liquid crystal molecules, the liquid crystal molecules 1440 can be changed. 'For example, the liquid crystal molecules 1440 are in parallel with each other', so that the line polarized light P passes through the liquid crystal bifurcation direction, and cannot pass the first Two polarizers 1880. It can be seen from the above that the polarizer is used to convert the light source into linearly polarized light, and a different electric field is applied to the liquid crystal molecules to convert the linearly polarized light into an ellipse, so that the gray scale image can be magnetically displayed, so generally in the liquid crystal display panel /Piece is the necessary design for LCD, Γί':-. '一々ίν.

[0005] However, in general, the function of the polarizer is such that the linearly polarized light of a certain polarization direction can pass through the polarizer, and the light perpendicular to the polarization direction is absorbed, that is, it absorbs forty-three to five percent. Ten rays of light result in lower light utilization. Therefore, how to improve the design of the liquid crystal display module to improve the light utilization efficiency of the liquid crystal display module and effectively utilize most of the natural light is still a subject of continuous research in the industry.
