Both Panasonic LX5 and Panasonic LX3 have 1/1.63-inch sized 10.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the LX5 and LX3 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic LX5 and Panasonic LX3 Cameras
Panasonic LX5 and Panasonic LX3 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
DxOMark Sensor Scores
Both Panasonic LX5 and Panasonic LX3 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Panasonic LX5
or the
Panasonic LX3 ,
including hyperfocal distance.
