Description of the invention (1) The present invention is a field emission display, especially a field emission display whose luminous intensity can be adjusted with the background light. 5 (Please read the precautions on the back before filling in the homepage) 5 11 In terms of the physical characteristics of the field emission display, it has the ability to display high-brightness images (2500cd / m2), so it can be used in harsh background light, high temperature, etc. It can be widely used in automobile, ship parking, aircraft instrument display or satellite navigation system under the environment, and it can also be applied to outdoor cameras. However, because the various devices that install the field emission display are often in a mobile state, the background light source The intensity of the light changes at any time. When changing from a strong background light to a weak background light, or from a weak background light to a strong background light, such as in and out of a tunnel or through the clouds, if the field can be adjusted at any time The brightness of the emission display, for example, the brightness of the image with a strong background light is adjusted to about 100 cd / m2, and when the backlight is weak, if the image brightness can be adjusted to about 60 cd / m2, it will be more suitable for ergonomic requirements and easier to watch. And it is not easy to make eyes tired. However, because the current field emission display does not have such adjustment control, it is easy to cause instantaneous blindness under the adjustment of human body functions, which may affect the driving safety of vehicles. In view of the above problems, the present invention provides an effective solution, the purpose of which is: Printed by the Consumers' Cooperative of the Economic Central Standards Bureau. 1. Provide a field emission display that can automatically adjust the brightness with the background. 2. Provide a device that can detect background light and control its voltage supply by combining one or more of the anode, cathode or gate electrode of the field emission display, so that the field emission display can adjust its brightness with the background light. The above purpose is mainly achieved by connecting one or more of the gate, cathode, or anode of the field emission display to a control driver, and making the control-2- this paper size applies to the Chinese National Standard (CNS) A4 specification ( 210X297 mm) 5
