illuminated keyboard

Abstract

The invention provides a luminous keyboard which comprises luminous elements, a thin film circuit board, a key bottom plate and a plurality of keys. The thin film circuit board comprises an upper layer plate and a lower layer plate. The upper layer plate is provided with a first circuit pattern with a plurality of thin film switches and a second circuit pattern with a plurality of thin film switches. The lower layer plate is provided with a first circuit pattern with a plurality of thin film switches and a second circuit pattern with a plurality of thin film switches. The lower layer plate further comprises a large amount of thin film which is used for increasing light guiding efficiency of the lower layer plate. The plurality of keys are arranged on the key bottom plate in a connecting mode, and the key bottom plate is arranged between the plurality of keys and the thin film circuit board. The luminous keyboard has the advantages of saving manufacturing cost and improving service efficiency of light.

Description

technical field [0001] The present invention relates to a keyboard, in particular to a luminous keyboard with a luminous function. Background technique [0002] In recent years, due to the rapid development of the information industry, many users may use portable information devices in different environments, such as notebook computers, mobile phones or personal digital assistants. In a low-light environment, users may not be able to clearly see the numbers and characters marked on the keyboard keys, thus causing difficulties in operation, and in severe cases, may even cause vision loss due to barely recognizing the key marks. Therefore, the launch of the luminous keyboard can improve the inconvenience of the user using the keyboard in places with insufficient light. What's more, with different lighting configurations, the information device using the lighting keyboard can look more beautiful, thereby increasing its sales. [0003] see figure 1 , which is a structural cro...

Problems solved by technology

[0012] However, Figure 4 The illustrated luminous keyboard still has two disadvantages of the aforementioned existing luminous keyboards, and because the thin film circuit board 94 has through holes 945 for respectively passing the first fixing structure 932 and the second fixing structure 933 of the key base plate 93 And the through hole 946, so that the light guiding effect of the lower layer board 941 of the thin film circuit board 94 cannot be continuous, that is to say, when the light provided by the light emitting element 96 encounters the through hole 945 or the through hole 946, it will stop advancing. Therefore, The luminous efficiency of the luminous keyboard 9 is greatly reduced

[0013] Therefore, the existing luminous keyboards 1 and 9 all have room for improvement due to poor light use efficiency
