Abstract

An electronic apparatus with a liquid crystal display comprises the following components. A liquid crystal display module has a backlight module and a glass panel, both are fastened in a display frame, wherein the display frame has a first fastening hole formed thereon. A digitizer comprises a sensor board and a control board connected together by a connecting bus, wherein the sensor board has a second fastening hole formed thereon and aligned with the first fastening hole when the sensor board is assembled into the liquid crystal display module. And a housing of the electronic apparatus is applied to receive the liquid crystal display module and the digitizer in the electronic apparatus, wherein the housing has a third fastening hole formed thereon and aligned with the second fastening hole and the first fastening hole. Thus by threading a screw through the first fastening hole, the second fastening hole and the third fastening hole, the liquid crystal display module and the digitizer can be fastened into the electronic apparatus.

Claims

1. A method for assembling a liquid crystal display into an electronic device, said method comprises the steps of:

providing a display frame which has a first fastening hole and a second fastening hole disposed on a peripheral region thereof;

disposing a glass panel on said display frame;

disposing a backlight module on said glass panel, wherein said backlight module has a third fastening hole aligned with said first fastening hole and a fourth fastening hole aligned with said second fastening hole respectively;

threading a first screw through said first fastening hole and said third fastening hole for fastening said display frame and said backlight module together and fixing said glass panel therebetween;

placing a digitizer on said liquid crystal display module, wherein said digitizer comprises a sensor board and a control board which is connected with said sensor board via a connecting bus, said sensor board is placed on said backlight module and has a fifth fastening hole formed thereon, wherein said fifth fastening hole is aligned with said fourth fastening hole and said second fastening hole;

providing an electronic apparatus for receiving said liquid crystal display module and said digitizer, wherein a housing of said electronic apparatus has a sixth fastening hole formed thereon and aligned with said fifth fastening hole, said fourth fastening hole and said second fastening hole; and

threading a second screw through said sixth fastening hole, said fifth fastening hole, said fourth fastening hole and said second fastening hole for fastening said liquid crystal display module and said digitizer into said electronic apparatus.

2. An electronic apparatus with a liquid crystal display comprising:

a liquid crystal display module having;

a backlight module assembled in a casing, wherein said casing has a first fastening hole and a second fastening hole formed thereon;

a glass panel placed on said casing of said backlight module;

a display frame placed on said glass panel, wherein said display frame has a third fastening hole aligned with said first fastening hole and a fourth fastening hole aligned with said second fastening hole respectively;

wherein a screw is threaded through said first fastening hole and said third fastening hole for fastening said display frame and said backlight module together and fixing said glass panel therebetween;
