New description: [New technical field] The present invention is a structure for improving the color mixture of the backlight module of the liquid crystal display panel, which means that a recess is formed at a proper position of the light guide plate to make the light When the diode emits colored light of different colors at the same time, the colored light of the different colors does not cause a diffusing phenomenon to cause color mixing, thereby enabling the user to clearly display the warning by different color light color regions when viewing the liquid crystal display panel. The structure of the effect to remind the user. [Prior Art] _ Press, nowadays more and more electronic products are displayed using the LCD panel to display the results. It is more desirable to display the results with different color backgrounds as a warning to allow users to have different color blocks. It is easy to know the results and deepen the impression. For example, red indicates that the standard value or set value is exceeded, and green indicates normal or general standard value, while yellow is close to the dangerous value. Pay special attention to etc. However, the liquid is not displayed on the surface of the liquid. It is referred to in the first and second figures. It is a type of liquid crystal display panel used in the electronic blood pressure. The liquid crystal display panel is mainly disposed on the surface of a casing 50. 7 〇 can display a number or a text or a pattern, and a reflective plate 1 下 is disposed under the liquid crystal display panel 70 , and a light guide plate 90 is disposed between the reflective plate 1 〇〇 and the liquid crystal display panel 70 , and the light guide plate 90 — Two light-emitting diodes (LEDs) 80 are embedded in the side, and the light-emitting diodes 80 can generate colored light of different colors, and the light-emitting diodes 80 maintain a certain distance, and the light-emitting diodes The color light generated by the body 80 can enhance the background display effect of the liquid crystal display panel 70 by the light guide plate 90 and the reflector 1 , and the light-emitting diodes 80 can be preset by the user according to the blood pressure measurement results. The color of the normal or reminding or dangerous light is displayed. For example, the normal blood pressure value is displayed in green light, the near danger value is displayed in yellow light, and the dangerous value is displayed in red light. However, when the device is constructed, if the blood pressure value measured by the user is normal, but the hypotensive value exceeds the dangerous value, the green and red colored colors respectively generated by the light-emitting diode 80 are respectively used. When the light is projected on the back surface of the liquid crystal display panel 70 through the light guide plate 90 and the reflection plate 1 respectively, the color light generated by the light-emitting diode 80 is gradually diffused outward at a certain angle when it is projected outward. 5 M293398 The light-emitting diodes 80 have overlapping colors of different colors in the adjacent areas on the light guide plate 90, and the color mixing effect is generated, thereby causing the user to be unclear and unable to effectively enhance the warning. The purpose of the person is therefore very unsatisfactory in use. [New content] Purpose of creation: In view of the lack of the backlight module display device of the liquid crystal display panel of the aforementioned electronic device, the creator has studied the structure of the color mixture of the backlight module of the liquid crystal display panel.
